fun AlertDialog(
    onDismissRequest: () -> Unit,
    modifier: Modifier = Modifier,
    properties: DialogProperties = DialogProperties(),

Basic alert dialog dialog.

Dialogs provide important prompts in a user flow. They can require an action, communicate information, or help users accomplish a task.

![Basic dialog

  • image](https://developer.android.com/images/reference/androidx/compose/material3/basic-dialog.png)

This basic alert dialog expects an arbitrary content that is defined by the caller. Note that your content will need to define its own styling.

By default, the displayed dialog has the minimum height and width that the Material Design spec defines. If required, these constraints can be overwritten by providing a width or height Modifiers.

Material Design basic dialog.

Dialogs provide important prompts in a user flow. They can require an action, communicate information, or help users accomplish a task.

![Basic dialog

  • image](https://developer.android.com/images/reference/androidx/compose/material3/basic-dialog.png)

The dialog will position its buttons, typically TextButtons, based on the available space. By default it will try to place them horizontally next to each other and fallback to horizontal placement if not enough space is available.

Simple usage:

import androidx.compose.material3.AlertDialog
import androidx.compose.material3.Text
import androidx.compose.material3.TextButton
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember

val openDialog = remember { mutableStateOf(true) }

if (openDialog.value) {
    AlertDialog(
        onDismissRequest = {
            // Dismiss the dialog when the user clicks outside the dialog or on the back
            // button. If you want to disable that functionality, simply use an empty
            // onDismissRequest.
            openDialog.value = false
        },
        title = { Text(text = "Title") },
        text = { Text(text = "Turned on by default") },
        confirmButton = {
            TextButton(onClick = { openDialog.value = false }) { Text("Confirm") }
        },
        dismissButton = {
            TextButton(onClick = { openDialog.value = false }) { Text("Dismiss") }
        }
    )
}

import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material3.AlertDialog
import androidx.compose.material3.Icon
import androidx.compose.material3.Text
import androidx.compose.material3.TextButton

    )
}
Parameters
onDismissRequest: () -> Unit

called when the user tries to dismiss the Dialog by clicking outside or pressing the back button. This is not called when the dismiss button is clicked.
confirmButton: @Composable () -> Unit

button which is meant to confirm a proposed action, thus resolving what triggered the dialog. The dialog does not set up any events for this button so they need to be set up by the caller.
modifier: Modifier = Modifier

the Modifier to be applied to this dialog
dismissButton: (@Composable () -> Unit)? = null

button which is meant to dismiss the dialog. The dialog does not set up any events for this button so they need to be set up by the caller.
icon: (@Composable () -> Unit)? = null

optional icon that will appear above the title or above the text, in case a title was not provided.
title: (@Composable () -> Unit)? = null

title which should specify the purpose of the dialog. The title is not mandatory, because there may be sufficient information inside the text.
text: (@Composable () -> Unit)? = null

text which presents the details regarding the dialog's purpose.
shape: Shape = AlertDialogDefaults.shape

defines the shape of this dialog's container
containerColor: Color = AlertDialogDefaults.containerColor

the color used for the background of this dialog. Use Color.Transparent to have no color.
iconContentColor: Color = AlertDialogDefaults.iconContentColor

the content color used for the icon.
titleContentColor: Color = AlertDialogDefaults.titleContentColor

the content color used for the title.
textContentColor: Color = AlertDialogDefaults.textContentColor

the content color used for the text.
tonalElevation: Dp = AlertDialogDefaults.TonalElevation

when containerColor is ColorScheme.surface, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: Surface.
properties: DialogProperties = DialogProperties()

typically platform specific properties to further configure the dialog.

    shape: Shape = AssistChipDefaults.shape,
    colors: ChipColors = AssistChipDefaults.assistChipColors(),
    elevation: ChipElevation? = AssistChipDefaults.assistChipElevation(),
    border: BorderStroke? = AssistChipDefaults.assistChipBorder(enabled),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design assist chip.

Chips help people enter information, make selections, filter content, or trigger actions. Chips can show multiple interactive elements together in the same area, such as a list of selectable movie times, or a series of email contacts.

Assist chips represent smart or automated actions that can span multiple apps, such as opening a calendar event from the home screen. Assist chips function as though the user asked an assistant to complete the action. They should appear dynamically and contextually in a UI.

![Assist chip

  • image](https://developer.android.com/images/reference/androidx/compose/material3/assist-chip.png)

This assist chip is applied with a flat style. If you want an elevated style, use the ElevatedAssistChip.

Example of a flat AssistChip:

import androidx.compose.foundation.layout.size
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Settings
import androidx.compose.material3.AssistChip
import androidx.compose.material3.AssistChipDefaults
import androidx.compose.material3.Icon
import androidx.compose.material3.Text
import androidx.compose.ui.Modifier

AssistChip(
    onClick = { /* Do something! */ },
    label = { Text("Assist Chip") },
    leadingIcon = {
        Icon(
            Icons.Filled.Settings,
            contentDescription = "Localized description",
            Modifier.size(AssistChipDefaults.IconSize)
        )
    }
)
Parameters
onClick: () -> Unit

called when this chip is clicked
label: @Composable () -> Unit

text label for this chip
modifier: Modifier = Modifier

the Modifier to be applied to this chip
enabled: Boolean = true

controls the enabled state of this chip. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
leadingIcon: (@Composable () -> Unit)? = null

optional icon at the start of the chip, preceding the label text
trailingIcon: (@Composable () -> Unit)? = null

optional icon at the end of the chip
shape: Shape = AssistChipDefaults.shape

defines the shape of this chip's container, border (when border is not null), and shadow (when using elevation)
colors: ChipColors = AssistChipDefaults.assistChipColors()

ChipColors that will be used to resolve the colors used for this chip in different states. See AssistChipDefaults.assistChipColors.
elevation: ChipElevation? = AssistChipDefaults.assistChipElevation()

ChipElevation used to resolve the elevation for this chip in different states. This controls the size of the shadow below the chip. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. See AssistChipDefaults.assistChipElevation.
border: BorderStroke? = AssistChipDefaults.assistChipBorder(enabled)

the border to draw around the container of this chip. Pass null for no border. See AssistChipDefaults.assistChipBorder.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this chip. You can use this to change the chip's appearance or preview the chip in different states. Note that if null is provided, interactions will still happen internally.

fun BasicAlertDialog(
    onDismissRequest: () -> Unit,
    modifier: Modifier = Modifier,
    properties: DialogProperties = DialogProperties(),

): Unit

Basic alert dialog dialog.

Dialogs provide important prompts in a user flow. They can require an action, communicate information, or help users accomplish a task.

![Basic dialog

  • image](https://developer.android.com/images/reference/androidx/compose/material3/basic-dialog.png)

This basic alert dialog expects an arbitrary content that is defined by the caller. Note that your content will need to define its own styling.

By default, the displayed dialog has the minimum height and width that the Material Design spec defines. If required, these constraints can be overwritten by providing a width or height Modifiers.

If you are interested in displaying a FloatingActionButton, consider using another overload.

Also see NavigationBar.

Parameters
modifier: Modifier = Modifier

the Modifier to be applied to this BottomAppBar
containerColor: Color = BottomAppBarDefaults.containerColor

the color used for the background of this BottomAppBar. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(containerColor)

the preferred color for content inside this BottomAppBar. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
tonalElevation: Dp = BottomAppBarDefaults.ContainerElevation

when containerColor is ColorScheme.surface, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: Surface.
contentPadding: PaddingValues = BottomAppBarDefaults.ContentPadding

the padding applied to the content of this BottomAppBar
windowInsets: WindowInsets = BottomAppBarDefaults.windowInsets

a window insets that app bar will respect.
content: @Composable RowScope.() -> Unit

the content of this BottomAppBar. The default layout here is a Row, so content inside will be placed horizontally.

Material Design standard bottom sheet scaffold.

Standard bottom sheets co-exist with the screen’s main UI region and allow for simultaneously viewing and interacting with both regions. They are commonly used to keep a feature or secondary content visible on screen when content in main UI region is frequently scrolled or panned.

![Bottom sheet

  • image](https://developer.android.com/images/reference/androidx/compose/material3/bottom_sheet.png)

This component provides API to put together several material components to construct your screen, by ensuring proper layout strategy for them and collecting necessary data so these components will work together correctly.

A simple example of a standard bottom sheet looks like this:

import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.padding
import androidx.compose.material3.BottomSheetScaffold
import androidx.compose.material3.Button
import androidx.compose.material3.Text
import androidx.compose.material3.rememberBottomSheetScaffoldState
import androidx.compose.runtime.remember
import androidx.compose.runtime.rememberCoroutineScope
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

val scope = rememberCoroutineScope()
val scaffoldState = rememberBottomSheetScaffoldState()

BottomSheetScaffold(
    scaffoldState = scaffoldState,
    sheetPeekHeight = 128.dp,
    sheetContent = {
        Column(Modifier.fillMaxWidth(), horizontalAlignment = Alignment.CenterHorizontally) {
            Box(Modifier.fillMaxWidth().height(128.dp), contentAlignment = Alignment.Center) {
                Text("Swipe up to expand sheet")
            }
            Text("Sheet content")
            Button(
                modifier = Modifier.padding(bottom = 64.dp),
                onClick = { scope.launch { scaffoldState.bottomSheetState.partialExpand() } }
            ) {
                Text("Click to collapse sheet")
            }
        }
    }
) { innerPadding ->
    Box(
        modifier = Modifier.fillMaxSize().padding(innerPadding),
        contentAlignment = Alignment.Center
    ) {
        Text("Scaffold Content")
    }
}
Parameters
sheetContent: @Composable ColumnScope.() -> Unit

the content of the bottom sheet
modifier: Modifier = Modifier

the Modifier to be applied to this scaffold
scaffoldState: BottomSheetScaffoldState = rememberBottomSheetScaffoldState()

the state of the bottom sheet scaffold
sheetPeekHeight: Dp = BottomSheetDefaults.SheetPeekHeight

the height of the bottom sheet when it is collapsed
sheetMaxWidth: Dp = BottomSheetDefaults.SheetMaxWidth

Dp that defines what the maximum width the sheet will take. Pass in Dp.Unspecified for a sheet that spans the entire screen width.
sheetShape: Shape = BottomSheetDefaults.ExpandedShape

the shape of the bottom sheet
sheetContainerColor: Color = BottomSheetDefaults.ContainerColor

the background color of the bottom sheet
sheetContentColor: Color = contentColorFor(sheetContainerColor)

the preferred content color provided by the bottom sheet to its children. Defaults to the matching content color for sheetContainerColor, or if that is not a color from the theme, this will keep the same content color set above the bottom sheet.
sheetTonalElevation: Dp = 0.dp

when sheetContainerColor is ColorScheme.surface, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: Surface.
sheetShadowElevation: Dp = BottomSheetDefaults.Elevation

the shadow elevation of the bottom sheet
sheetDragHandle: (@Composable () -> Unit)? = { BottomSheetDefaults.DragHandle() }

optional visual marker to pull the scaffold's bottom sheet
sheetSwipeEnabled: Boolean = true

whether the sheet swiping is enabled and should react to the user's input
topBar: (@Composable () -> Unit)? = null

top app bar of the screen, typically a TopAppBar
snackbarHost: @Composable (SnackbarHostState) -> Unit = { SnackbarHost(it) }

component to host Snackbars that are pushed to be shown via SnackbarHostState.showSnackbar, typically a SnackbarHost
containerColor: Color = MaterialTheme.colorScheme.surface

the color used for the background of this scaffold. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(containerColor)

the preferred color for content inside this scaffold. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
content: @Composable (PaddingValues) -> Unit

content of the screen. The lambda receives a PaddingValues that should be applied to the content root via Modifier.padding and Modifier.consumeWindowInsets to properly offset top and bottom bars. If using Modifier.verticalScroll, apply this modifier to the child of the scroll, and not on the scroll itself.

Button

Cmn 
@Composable
fun Button(
    onClick: () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    shape: Shape = ButtonDefaults.shape,
    colors: ButtonColors = ButtonDefaults.buttonColors(),
    elevation: ButtonElevation? = ButtonDefaults.buttonElevation(),
    border: BorderStroke? = null,
    contentPadding: PaddingValues = ButtonDefaults.ContentPadding,
    interactionSource: MutableInteractionSource? = null,
    content: @Composable RowScope.() -> Unit
): Unit

Material Design button.

Buttons help people initiate actions, from sending an email, to sharing a document, to liking a post.

![Filled button

  • image](https://developer.android.com/images/reference/androidx/compose/material3/filled-button.png)

Filled buttons are high-emphasis buttons. Filled buttons have the most visual impact after the FloatingActionButton, and should be used for important, final actions that complete a flow, like "Save", "Join now", or "Confirm".

    Spacer(Modifier.size(ButtonDefaults.IconSpacing))
    Text("Like")
}

Button that uses a square shape instead of the default round shape:

import androidx.compose.material3.Button
import androidx.compose.material3.ButtonDefaults
import androidx.compose.material3.Text

Button(onClick = { /* Do something! */ }, shape = ButtonDefaults.squareShape) { Text("Button") }

Button that utilizes the small design content padding:

import androidx.compose.material3.Button
import androidx.compose.material3.ButtonDefaults
import androidx.compose.material3.Text

Button(
    onClick = { /* Do something! */ },
    contentPadding = ButtonDefaults.SmallButtonContentPadding
) {
    Text("Button")
}

Choose the best button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

The default text style for internal Text components will be set to Typography.labelLarge.

Parameters
onClick: () -> Unit

called when this button is clicked
modifier: Modifier = Modifier

the Modifier to be applied to this button
enabled: Boolean = true

controls the enabled state of this button. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
shape: Shape = ButtonDefaults.shape

defines the shape of this button's container, border (when border is not null), and shadow (when using elevation)
colors: ButtonColors = ButtonDefaults.buttonColors()

ButtonColors that will be used to resolve the colors for this button in different states. See ButtonDefaults.buttonColors.
elevation: ButtonElevation? = ButtonDefaults.buttonElevation()

ButtonElevation used to resolve the elevation for this button in different states. This controls the size of the shadow below the button. See ButtonElevation.shadowElevation.
border: BorderStroke? = null

the border to draw around the container of this button
contentPadding: PaddingValues = ButtonDefaults.ContentPadding

the spacing values to apply internally between the container and the content
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this button. You can use this to change the button's appearance or preview the button in different states. Note that if null is provided, interactions will still happen internally.
content: @Composable RowScope.() -> Unit

The content displayed on the button, expected to be text, icon or image.

ButtonGroup

Cmn 
@Composable
@ExperimentalMaterial3ExpressiveApi
fun ButtonGroup(
    modifier: Modifier = Modifier,
    animateFraction: @FloatRange(from = 0.0) Float = ButtonGroupDefaults.animateFraction,
    horizontalArrangement: Arrangement.Horizontal = Arrangement.spacedBy(ButtonGroupDefaults.spaceBetween),
    content: @Composable ButtonGroupScope.() -> Unit
): Unit

TODO link to mio page when available.

A layout composable that places its children in a horizontal sequence. When a child uses Modifier.interactionSourceData with a relevant MutableInteractionSource, this button group can listen to the interactions and expand the width of the pressed child element as well as compress the neighboring child elements. Material3 components already use Modifier.interactionSourceData and will behave as expected.

)
Parameters
title: @Composable () -> Unit

the title to be displayed in the top app bar
modifier: Modifier = Modifier

the Modifier to be applied to this top app bar
navigationIcon: @Composable () -> Unit = {}

the navigation icon displayed at the start of the top app bar. This should typically be an IconButton or IconToggleButton.
actions: @Composable RowScope.() -> Unit = {}

the actions displayed at the end of the top app bar. This should typically be IconButtons. The default layout here is a Row, so icons inside will be placed horizontally.
expandedHeight: Dp = TopAppBarDefaults.TopAppBarExpandedHeight

this app bar's height. When a specified scrollBehavior causes the app bar to collapse or expand, this value will represent the maximum height that the bar will be allowed to expand. This value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.TopAppBarExpandedHeight.
windowInsets: WindowInsets = TopAppBarDefaults.windowInsets

a window insets that app bar will respect.
colors: TopAppBarColors = TopAppBarDefaults.centerAlignedTopAppBarColors()

TopAppBarColors that will be used to resolve the colors used for this top app bar in different states. See TopAppBarDefaults.centerAlignedTopAppBarColors.
scrollBehavior: TopAppBarScrollBehavior? = null

a TopAppBarScrollBehavior which holds various offset values that will be applied by this top app bar to set up its height and colors. A scroll behavior is designed to work in conjunction with a scrolled content to change the top app bar appearance as the content scrolls. See TopAppBarScrollBehavior.nestedScrollConnection.

By default there is no animation between progress values. You can use ProgressIndicatorDefaults.ProgressAnimationSpec as the default recommended AnimationSpec when animating progress, such as in the following example:

import androidx.compose.animation.core.animateFloatAsState
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.requiredHeight
import androidx.compose.foundation.layout.width
import androidx.compose.material3.CircularWavyProgressIndicator
import androidx.compose.material3.ProgressIndicatorDefaults
import androidx.compose.material3.Slider
import androidx.compose.material3.Text
import androidx.compose.runtime.getValue
import androidx.compose.runtime.mutableFloatStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

var progress by remember { mutableFloatStateOf(0.1f) }
val animatedProgress by
    animateFloatAsState(
        targetValue = progress,
        animationSpec = ProgressIndicatorDefaults.ProgressAnimationSpec
    )

Column(horizontalAlignment = Alignment.CenterHorizontally) {
    CircularWavyProgressIndicator(progress = { animatedProgress })
    Spacer(Modifier.requiredHeight(30.dp))
    Text("Set progress:")
    Slider(
        modifier = Modifier.width(300.dp),
        value = progress,
        valueRange = 0f..1f,
        onValueChange = { progress = it },
    )
}

You may also follow the Material guidelines to create a thicker version of this indicator, like in this example:

import androidx.compose.animation.core.animateFloatAsState
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.requiredHeight

import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.StrokeCap
import androidx.compose.ui.graphics.drawscope.Stroke
import androidx.compose.ui.platform.LocalDensity

var progress by remember { mutableFloatStateOf(0.1f) }
val animatedProgress by
    animateFloatAsState(
        targetValue = progress,
        animationSpec = ProgressIndicatorDefaults.ProgressAnimationSpec
    )
val thickStrokeWidth = with(LocalDensity.current) { 8.dp.toPx() }
val thickStroke =
    remember(thickStrokeWidth) { Stroke(width = thickStrokeWidth, cap = StrokeCap.Round) }
Column(horizontalAlignment = Alignment.CenterHorizontally) {
    CircularWavyProgressIndicator(
        progress = { animatedProgress },
        // Thick size is slightly larger than the
        // WavyProgressIndicatorDefaults.CircularContainerSize default
        modifier = Modifier.size(52.dp), // Thick size is slightly larger than the default
        stroke = thickStroke,
        trackStroke = thickStroke,
    )
    Spacer(Modifier.requiredHeight(30.dp))
    Text("Set progress:")
    Slider(

Material Design date picker.

Date pickers let people select a date and preferably should be embedded into Dialogs. See DatePickerDialog.

By default, a date picker lets you pick a date via a calendar UI. However, it also allows switching into a date input mode for a manual entry of dates using the numbers on a keyboard.

![Date picker

  • image](https://developer.android.com/images/reference/androidx/compose/material3/date-picker.png)

A simple DatePicker looks like:

import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.rememberScrollState
import androidx.compose.foundation.verticalScroll
import androidx.compose.material3.DatePicker
import androidx.compose.material3.DatePickerState
import androidx.compose.material3.Text
import androidx.compose.material3.rememberDatePickerState
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

Column(
    modifier = Modifier.verticalScroll(rememberScrollState()),
    verticalArrangement = Arrangement.spacedBy(8.dp)
) {
    // Pre-select a date for January 4, 2020
    val datePickerState = rememberDatePickerState(initialSelectedDateMillis = 1578096000000)
    DatePicker(state = datePickerState, modifier = Modifier.padding(16.dp))

    Text(
        "Selected date timestamp: ${datePickerState.selectedDateMillis ?: "no selection"}",
        modifier = Modifier.align(Alignment.CenterHorizontally)
    )
}

A DatePicker with an initial UI of a date input mode looks like:

import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.padding
import androidx.compose.material3.DatePicker
import androidx.compose.material3.DatePickerState
import androidx.compose.material3.DisplayMode

import androidx.compose.material3.rememberDatePickerState
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

Column(verticalArrangement = Arrangement.spacedBy(8.dp)) {
    val state = rememberDatePickerState(initialDisplayMode = DisplayMode.Input)
    DatePicker(state = state, modifier = Modifier.padding(16.dp))

    Text(
        "Entered date timestamp: ${state.selectedDateMillis ?: "no input"}",
        modifier = Modifier.align(Alignment.CenterHorizontally)
    )
}

A DatePicker with a provided SelectableDates that blocks certain days from being selected looks like:

import androidx.compose.foundation.layout.Arrangement

import androidx.compose.material3.DatePicker
import androidx.compose.material3.DatePickerState

val datePickerState =
    rememberDatePickerState(
        selectableDates =
            object : SelectableDates {
                // Blocks Sunday and Saturday from being selected.
                override fun isSelectableDate(utcTimeMillis: Long): Boolean {

                        val dayOfWeek =
                            Instant.ofEpochMilli(utcTimeMillis)
                                .atZone(ZoneId.of("UTC"))
                                .toLocalDate()
                                .dayOfWeek
                        dayOfWeek != DayOfWeek.SUNDAY && dayOfWeek != DayOfWeek.SATURDAY
                    } else {
                        val calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"))
                        calendar.timeInMillis = utcTimeMillis
                        calendar[Calendar.DAY_OF_WEEK] != Calendar.SUNDAY &&
                            calendar[Calendar.DAY_OF_WEEK] != Calendar.SATURDAY
                    }
                }

                // Allow selecting dates from year 2023 forward.
                override fun isSelectableYear(year: Int): Boolean {
                    return year > 2022
                }
            }
    )

Column(
    modifier = Modifier.verticalScroll(rememberScrollState()),
    verticalArrangement = Arrangement.spacedBy(8.dp)
) {
    DatePicker(state = datePickerState)
    Text(
        "Selected date timestamp: ${datePickerState.selectedDateMillis ?: "no selection"}",
        modifier = Modifier.align(Alignment.CenterHorizontally)

import androidx.compose.foundation.rememberScrollState
import androidx.compose.foundation.verticalScroll
import androidx.compose.material3.DatePicker
import androidx.compose.material3.DatePickerDialog
import androidx.compose.material3.DatePickerState
import androidx.compose.material3.DisplayMode
import androidx.compose.material3.SnackbarHost
import androidx.compose.material3.SnackbarHostState
import androidx.compose.material3.Text
import androidx.compose.material3.TextButton
import androidx.compose.material3.rememberDatePickerState
import androidx.compose.runtime.derivedStateOf
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.runtime.rememberCoroutineScope
import androidx.compose.ui.Modifier

// Decoupled snackbar host state from scaffold state for demo purposes.
val snackState = remember { SnackbarHostState() }
val snackScope = rememberCoroutineScope()
SnackbarHost(hostState = snackState, Modifier)
val openDialog = remember { mutableStateOf(true) }
// TODO demo how to read the selected date from the state.
if (openDialog.value) {
    val datePickerState = rememberDatePickerState()
    val confirmEnabled = remember {
        derivedStateOf { datePickerState.selectedDateMillis != null }
    }
    DatePickerDialog(
        onDismissRequest = {
            // Dismiss the dialog when the user clicks outside the dialog or on the back
            // button. If you want to disable that functionality, simply use an empty
            // onDismissRequest.
            openDialog.value = false
        },
        confirmButton = {
            TextButton(
                onClick = {
                    openDialog.value = false
                    snackScope.launch {
                        snackState.showSnackbar(
                            "Selected date timestamp: ${datePickerState.selectedDateMillis}"
                        )
                    }
                },
                enabled = confirmEnabled.value
            ) {
                Text("OK")
            }
        },
        dismissButton = {
            TextButton(onClick = { openDialog.value = false }) { Text("Cancel") }
        }
    ) {
        // The verticalScroll will allow scrolling to show the entire month in case there is not
        // enough horizontal space (for example, when in landscape mode).
        // Note that it's still currently recommended to use a DisplayMode.Input at the state in
        // those cases.
        DatePicker(
            state = datePickerState,
            modifier = Modifier.verticalScroll(rememberScrollState())
        )
    }
}
Parameters
onDismissRequest: () -> Unit

called when the user tries to dismiss the Dialog by clicking outside or pressing the back button. This is not called when the dismiss button is clicked.
confirmButton: @Composable () -> Unit

button which is meant to confirm a proposed action, thus resolving what triggered the dialog. The dialog does not set up any events for this button, nor does it control its enablement, so those need to be set up by the caller.
modifier: Modifier = Modifier

the Modifier to be applied to this dialog's content.
dismissButton: (@Composable () -> Unit)? = null

button which is meant to dismiss the dialog. The dialog does not set up any events for this button so they need to be set up by the caller.
shape: Shape = DatePickerDefaults.shape

defines the dialog's surface shape as well its shadow
tonalElevation: Dp = DatePickerDefaults.TonalElevation

when DatePickerColors.containerColor is ColorScheme.surface, a higher the elevation will result in a darker color in light theme and lighter color in dark theme
colors: DatePickerColors = DatePickerDefaults.colors()

DatePickerColors that will be used to resolve the colors used for this date picker in different states. See DatePickerDefaults.colors.
properties: DialogProperties = DialogProperties(usePlatformDefaultWidth = false)

typically platform specific properties to further configure the dialog
content: @Composable ColumnScope.() -> Unit

the content of the dialog (i.e. a DatePicker, for example)

DatePickerState

Cmn 
@ExperimentalMaterial3Api
fun DatePickerState(
    locale: CalendarLocale,
    initialSelectedDateMillis: Long? = null,
    initialDisplayedMonthMillis: Long? = initialSelectedDateMillis,
    yearRange: IntRange = DatePickerDefaults.YearRange,
    initialDisplayMode: DisplayMode = DisplayMode.Picker,
    selectableDates: SelectableDates = DatePickerDefaults.AllDates
): DatePickerState

Creates a DatePickerState.

For most cases, you are advised to use the rememberDatePickerState when in a composition.

Note that in case you provide a locale that is different than the default platform locale, you may need to ensure that the picker's title and headline localized correctly. The following sample shows one possible way of doing so by applying a local composition of a LocalContext and LocaleConfiguration.

import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column

val preferredLocales = LocaleList.forLanguageTags("HE")
val config = Configuration()
config.setLocales(preferredLocales)
val newContext = LocalContext.current.createConfigurationContext(config)
CompositionLocalProvider(
    LocalContext provides newContext,
    LocalConfiguration provides config,
    LocalLayoutDirection provides LayoutDirection.Rtl
) {
    Column(
        modifier = Modifier.verticalScroll(rememberScrollState()),
        verticalArrangement = Arrangement.spacedBy(8.dp)
    ) {
        // Pre-select a date for January 4, 2020
        // Initialize date picker with the preferred locale. Here we create a state directly,
        // but since the Locale was set at the CompositionLocalProvider through a Configuration,
        // a `val datePickerState = rememberDatePickerState(...)` will have the same effect.
        val datePickerState = remember {
            DatePickerState(
                initialSelectedDateMillis = 1578096000000,
                // Set to "HE" locale.
                locale = preferredLocales.get(0)
            )
        }
        DatePicker(state = datePickerState, modifier = Modifier.padding(16.dp))

        Text(
            "Selected date timestamp: ${datePickerState.selectedDateMillis ?: "no selection"}",
            modifier = Modifier.align(Alignment.CenterHorizontally)
        )
    }
}
Parameters
locale: CalendarLocale

the CalendarLocale that will be used when formatting dates, determining the input format, displaying the week-day, determining the first day of the week, and more. Note that in case the provided CalendarLocale differs from the platform's default Locale, you may need to ensure that the picker's title and headline localized correctly, and in some cases, you may need to apply an RTL layout.
initialSelectedDateMillis: Long? = null

timestamp in UTC milliseconds from the epoch that represents an initial selection of a date. Provide a null to indicate no selection. Note that the state's DatePickerState.selectedDateMillis will provide a timestamp that represents the start of the day, which may be different than the provided initialSelectedDateMillis.
initialDisplayedMonthMillis: Long? = initialSelectedDateMillis

timestamp in UTC milliseconds from the epoch that represents an initial selection of a month to be displayed to the user. In case null is provided, the displayed month would be the current one.
yearRange: IntRange = DatePickerDefaults.YearRange

an IntRange that holds the year range that the date picker will be limited to
initialDisplayMode: DisplayMode = DisplayMode.Picker

an initial DisplayMode that this state will hold
selectableDates: SelectableDates = DatePickerDefaults.AllDates

a SelectableDates that is consulted to check if a date is allowed. In case a date is not allowed to be selected, it will appear disabled in the UI.
Throws
kotlin.IllegalArgumentException

if the initial selected date or displayed month represent a year that is out of the year range.

    properties: ModalWideNavigationRailProperties = DismissibleModalWideNavigationRailDefaults.Properties,
    content: @Composable () -> Unit
): Unit

A dismissible modal wide navigation rail.

Wide navigation rails provide access to primary destinations in apps when using tablet and desktop screens.

The dismissible modal wide navigation rail blocks interaction with the rest of an app’s content with a scrim when expanded. It is elevated above most of the app’s UI and doesn't affect the screen’s layout grid. When collapsed, the rail is hidden.

The dismissible modal wide navigation rai should be used to display at least three WideNavigationRailItems with their icon position set to NavigationItemIconPosition.Start, each representing a singular app destination, and, optionally, a header containing a menu button, a FloatingActionButton, and/or a logo. Each destination is typically represented by an icon and a text label. A simple example looks like:

Material Design navigation drawer.

Navigation drawers provide ergonomic access to destinations in an app. They’re often next to app content and affect the screen’s layout grid.

![Navigation drawer

  • image](https://developer.android.com/images/reference/androidx/compose/material3/navigation-drawer.png)

Dismissible standard drawers can be used for layouts that prioritize content (such as a photo gallery) or for apps where users are unlikely to switch destinations often. They should use a visible navigation menu icon to open and close the drawer.

Material Design search.

A search bar represents a floating search field that allows users to enter a keyword or phrase and get relevant information. It can be used as a way to navigate through an app via search queries.

An search bar expands into a search "view" and can be used to display dynamic suggestions or search results.

![Search bar

  • image](https://developer.android.com/images/reference/androidx/compose/material3/docked-search-bar.png)

A DockedSearchBar displays search results in a bounded table below the input field. It is an alternative to SearchBar when expanding to full-screen size is undesirable on large screens such as tablets.

Material Design dropdown menu.

Menus display a list of choices on a temporary surface. They appear when users interact with a button, action, or other control.

![Dropdown menu

  • image](https://developer.android.com/images/reference/androidx/compose/material3/menu.png)

A DropdownMenu behaves similarly to a Popup, and will use the position of the parent layout to position itself on screen. Commonly a DropdownMenu will be placed in a Box with a sibling that will be used as the 'anchor'. Note that a DropdownMenu by itself will not take up any space in a layout, as the menu is displayed in a separate window, on top of other content.

The content of a DropdownMenu will typically be DropdownMenuItems, as well as custom content. Using DropdownMenuItems will result in a menu that matches the Material specification for menus. Also note that the content is placed inside a scrollable Column, so using a LazyColumn as the root layout inside content is unsupported.

onDismissRequest will be called when the menu should close - for example when there is a tap outside the menu, or when the back key is pressed.

DropdownMenu changes its positioning depending on the available space, always trying to be fully visible. Depending on layout direction, first it will try to align its start to the start of its parent, then its end to the end of its parent, and then to the edge of the window. Vertically, it will try to align its top to the bottom of its parent, then its bottom to top of its parent, and then to the edge of the window.

An offset can be provided to adjust the positioning of the menu for cases when the layout bounds of its parent do not coincide with its visual bounds.

Material Design elevated assist chip.

Chips help people enter information, make selections, filter content, or trigger actions. Chips can show multiple interactive elements together in the same area, such as a list of selectable movie times, or a series of email contacts.

Assist chips represent smart or automated actions that can span multiple apps, such as opening a calendar event from the home screen. Assist chips function as though the user asked an assistant to complete the action. They should appear dynamically and contextually in a UI.

Buttons help people initiate actions, from sending an email, to sharing a document, to liking a post.

![Elevated button

  • image](https://developer.android.com/images/reference/androidx/compose/material3/elevated-button.png)

Elevated buttons are high-emphasis buttons that are essentially FilledTonalButtons with a shadow. To prevent shadow creep, only use them when absolutely necessary, such as when the button requires visual separation from patterned container.

import androidx.compose.material3.Button
import androidx.compose.material3.ElevatedButton
import androidx.compose.material3.Text

ElevatedButton(onClick = { /* Do something! */ }) { Text("Elevated Button") }

Choose the best button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

The default text style for internal Text components will be set to Typography.labelLarge.

    expanded: Boolean,
    onExpandedChange: (Boolean) -> Unit,
    modifier: Modifier = Modifier,
    content: @Composable ExposedDropdownMenuBoxScope.() -> Unit
): Unit

Material Design Exposed Dropdown Menu.

Menus display a list of choices on a temporary surface. They appear when users interact with a button, action, or other control.

Exposed dropdown menus, sometimes also called "spinners" or "combo boxes", display the currently selected item in a text field to which the menu is anchored. In some cases, it can accept and display user input (whether or not it’s listed as a menu choice), in which case it may be used to implement autocomplete.

![Exposed dropdown menu

  • image](https://developer.android.com/images/reference/androidx/compose/material3/exposed-dropdown-menu.png)

The ExposedDropdownMenuBox is expected to contain a TextField (or OutlinedTextField) and ExposedDropdownMenu as content. The menuAnchor modifier should be passed to the text field.

An example of a read-only Exposed Dropdown Menu:

![Filled tonal button

  • image](https://developer.android.com/images/reference/androidx/compose/material3/filled-tonal-button.png)

Filled tonal buttons are medium-emphasis buttons that is an alternative middle ground between default Buttons (filled) and OutlinedButtons. They can be used in contexts where lower-priority button requires slightly more emphasis than an outline would give, such as "Next" in an onboarding flow. Tonal buttons use the secondary color mapping.

import androidx.compose.material3.Button
import androidx.compose.material3.FilledTonalButton
import androidx.compose.material3.Text

FilledTonalButton(onClick = { /* Do something! */ }) { Text("Filled Tonal Button") }

Choose the best button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

The default text style for internal Text components will be set to Typography.labelLarge.

A filled tonal toggle icon button is a medium-emphasis icon button that is an alternative middle ground between the default FilledIconToggleButton and OutlinedIconToggleButton. They can be used in contexts where the lower-priority icon button requires slightly more emphasis than an outline would give.

content should typically be an Icon (see androidx.compose.material.icons.Icons). If using a custom icon, note that the typical size for the internal icon is 24 x 24 dp. This icon button has an overall minimum touch target size of 48 x 48dp, to meet accessibility guidelines.

FilterChip

Cmn 
@Composable
fun FilterChip(
    selected: Boolean,
    onClick: () -> Unit,
    label: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,

    elevation: SelectableChipElevation? = FilterChipDefaults.filterChipElevation(),
    border: BorderStroke? = FilterChipDefaults.filterChipBorder(enabled, selected),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design filter chip.

Chips help people enter information, make selections, filter content, or trigger actions. Chips can show multiple interactive elements together in the same area, such as a list of selectable movie times, or a series of email contacts.

Filter chips use tags or descriptive words to filter content. They can be a good alternative to toggle buttons or checkboxes.

![Filter chip

  • image](https://developer.android.com/images/reference/androidx/compose/material3/filter-chip.png)

This filter chip is applied with a flat style. If you want an elevated style, use the ElevatedFilterChip.

Tapping on a filter chip toggles its selection state. A selection state leadingIcon can be provided (e.g. a checkmark) to be appended at the starting edge of the chip's label.

Example of a flat FilterChip with a trailing icon:

import androidx.compose.foundation.layout.size
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Done
import androidx.compose.material3.FilterChip
import androidx.compose.material3.FilterChipDefaults
import androidx.compose.material3.Icon
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier

var selected by remember { mutableStateOf(false) }
FilterChip(
    selected = selected,
    onClick = { selected = !selected },
    label = { Text("Filter chip") },
    leadingIcon =
        if (selected) {
            {
                Icon(
                    imageVector = Icons.Filled.Done,
                    contentDescription = "Localized Description",
                    modifier = Modifier.size(FilterChipDefaults.IconSize)
                )
            }
        } else {
            null
        }
)

Example of a FilterChip with both a leading icon and a selected icon:

import androidx.compose.foundation.layout.size
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Done
import androidx.compose.material.icons.filled.Home

var selected by remember { mutableStateOf(false) }
FilterChip(
    selected = selected,
    onClick = { selected = !selected },
    label = { Text("Filter chip") },
    leadingIcon =
        if (selected) {
            {
                Icon(

Cmn 
@Composable
fun Icon(
    bitmap: ImageBitmap,
    contentDescription: String?,
    modifier: Modifier = Modifier,
    tint: Color = LocalContentColor.current
): Unit

A Material Design icon component that draws bitmap using tint, with a default value of LocalContentColor. If bitmap has no intrinsic size, this component will use the recommended default size. Icon is an opinionated component designed to be used with single-color icons so that they can be tinted correctly for the component they are placed in. For multicolored icons and icons that should not be tinted, use Color.Unspecified for tint. For generic images that should not be tinted, and do not follow the recommended icon size, use the generic androidx.compose.foundation.Image instead. For a clickable icon, see IconButton.

To learn more about icons, see Material Design icons

Parameters
bitmap: ImageBitmap

InputChip

Cmn 
@Composable
fun InputChip(
    selected: Boolean,
    onClick: () -> Unit,
    label: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,

    elevation: SelectableChipElevation? = InputChipDefaults.inputChipElevation(),
    border: BorderStroke? = InputChipDefaults.inputChipBorder(enabled, selected),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design input chip.

Chips help people enter information, make selections, filter content, or trigger actions. Chips can show multiple interactive elements together in the same area, such as a list of selectable movie times, or a series of email contacts.

Input chips represent discrete pieces of information entered by a user.

![Input chip

  • image](https://developer.android.com/images/reference/androidx/compose/material3/input-chip.png)

An Input Chip can have a leading icon or an avatar at its start. In case both are provided, the avatar will take precedence and will be displayed.

Example of an InputChip with a trailing icon:

import androidx.compose.material3.InputChip
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember

var selected by remember { mutableStateOf(false) }
InputChip(
    selected = selected,
    onClick = { selected = !selected },
    label = { Text("Input Chip") },
)

Example of an InputChip with an avatar and a trailing icon:

import androidx.compose.foundation.layout.size
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Person
import androidx.compose.material3.Icon
import androidx.compose.material3.InputChip
import androidx.compose.material3.InputChipDefaults
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier

var selected by remember { mutableStateOf(false) }
InputChip(
    selected = selected,
    onClick = { selected = !selected },
    label = { Text("Input Chip") },
    avatar = {
        Icon(
            Icons.Filled.Person,
            contentDescription = "Localized description",
            Modifier.size(InputChipDefaults.AvatarSize)
        )
    }
)

Input chips should appear in a set and can be horizontally scrollable:

import androidx.compose.foundation.horizontalScroll
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Row
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.rememberScrollState
import androidx.compose.material3.AssistChip
import androidx.compose.material3.Text
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

Column(horizontalAlignment = Alignment.CenterHorizontally) {
    Row(modifier = Modifier.horizontalScroll(rememberScrollState())) {
        repeat(9) { index ->
            AssistChip(
                modifier = Modifier.padding(horizontal = 4.dp),
                onClick = { /* do something*/ },
                label = { Text("Chip $index") }
            )
        }
    }
}

Parameters
selected: Boolean

whether this chip is selected or not
onClick: () -> Unit

called when this chip is clicked
label: @Composable () -> Unit

text label for this chip
modifier: Modifier = Modifier

the Modifier to be applied to this chip
enabled: Boolean = true

controls the enabled state of this chip. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
leadingIcon: (@Composable () -> Unit)? = null

optional icon at the start of the chip, preceding the label text
avatar: (@Composable () -> Unit)? = null

optional avatar at the start of the chip, preceding the label text
trailingIcon: (@Composable () -> Unit)? = null

optional icon at the end of the chip
shape: Shape = InputChipDefaults.shape

defines the shape of this chip's container, border (when border is not null), and shadow (when using elevation)
colors: SelectableChipColors = InputChipDefaults.inputChipColors()

ChipColors that will be used to resolve the colors used for this chip in different states. See InputChipDefaults.inputChipColors.
elevation: SelectableChipElevation? = InputChipDefaults.inputChipElevation()

ChipElevation used to resolve the elevation for this chip in different states. This controls the size of the shadow below the chip. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. See InputChipDefaults.inputChipElevation.
border: BorderStroke? = InputChipDefaults.inputChipBorder(enabled, selected)

the border to draw around the container of this chip. Pass null for no border. See InputChipDefaults.inputChipBorder.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this chip. You can use this to change the chip's appearance or preview the chip in different states. Note that if null is provided, interactions will still happen internally.

Parameters
title: @Composable () -> Unit

the title to be displayed in the top app bar. This title will be used in the app bar's expanded and collapsed states, although in its collapsed state it will be composed with a smaller sized TextStyle
modifier: Modifier = Modifier

the Modifier to be applied to this top app bar
navigationIcon: @Composable () -> Unit = {}

the navigation icon displayed at the start of the top app bar. This should typically be an IconButton or IconToggleButton.
actions: @Composable RowScope.() -> Unit = {}

the actions displayed at the end of the top app bar. This should typically be IconButtons. The default layout here is a Row, so icons inside will be placed horizontally.
collapsedHeight: Dp = TopAppBarDefaults.LargeAppBarCollapsedHeight

this app bar height when collapsed by a provided scrollBehavior. This value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.LargeAppBarCollapsedHeight.
expandedHeight: Dp = TopAppBarDefaults.LargeAppBarExpandedHeight

this app bar's maximum height. When a specified scrollBehavior causes the app bar to collapse or expand, this value will represent the maximum height that the app-bar will be allowed to expand. The expanded height is expected to be greater or equal to the collapsedHeight, and the function will throw an IllegalArgumentException otherwise. Also, this value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.LargeAppBarExpandedHeight.
windowInsets: WindowInsets = TopAppBarDefaults.windowInsets

a window insets that app bar will respect.
colors: TopAppBarColors = TopAppBarDefaults.largeTopAppBarColors()

TopAppBarColors that will be used to resolve the colors used for this top app bar in different states. See TopAppBarDefaults.largeTopAppBarColors.
scrollBehavior: TopAppBarScrollBehavior? = null

a TopAppBarScrollBehavior which holds various offset values that will be applied by this top app bar to set up its height and colors. A scroll behavior is designed to work in conjunction with a scrolled content to change the top app bar appearance as the content scrolls. See TopAppBarScrollBehavior.nestedScrollConnection.
Throws
kotlin.IllegalArgumentException

if the provided expandedHeight is smaller to the collapsedHeight

This version of a linear progress indicator accepts arguments, such as amplitude, wavelength, and waveSpeed to render the progress as a waveform.

By default there is no animation between progress values. You can use WavyProgressIndicatorDefaults.ProgressAnimationSpec as the default recommended AnimationSpec when animating progress, such as in the following example:

import androidx.compose.animation.core.animateFloatAsState
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.requiredHeight
import androidx.compose.foundation.layout.width
import androidx.compose.material3.LinearWavyProgressIndicator
import androidx.compose.material3.ProgressIndicatorDefaults
import androidx.compose.material3.Slider
import androidx.compose.material3.Text
import androidx.compose.runtime.getValue
import androidx.compose.runtime.mutableFloatStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

var progress by remember { mutableFloatStateOf(0.1f) }
val animatedProgress by
    animateFloatAsState(
        targetValue = progress,
        animationSpec = ProgressIndicatorDefaults.ProgressAnimationSpec
    )

Column(horizontalAlignment = Alignment.CenterHorizontally) {
    LinearWavyProgressIndicator(
        progress = { animatedProgress },
    )
    Spacer(Modifier.requiredHeight(30.dp))
    Text("Set progress:")
    Slider(
        modifier = Modifier.width(300.dp),
        value = progress,
        valueRange = 0f..1f,
        onValueChange = { progress = it },
    )
}

You may also follow the Material guidelines to create a thicker version of this indicator, like in this example:

import androidx.compose.animation.core.animateFloatAsState
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.requiredHeight

    )

val thickStrokeWidth = with(LocalDensity.current) { 8.dp.toPx() }
val thickStroke =
    remember(thickStrokeWidth) { Stroke(width = thickStrokeWidth, cap = StrokeCap.Round) }

Column(horizontalAlignment = Alignment.CenterHorizontally) {
    LinearWavyProgressIndicator(
        progress = { animatedProgress },
        // Thick height is slightly higher than the
        // WavyProgressIndicatorDefaults.LinearContainerHeight default
        modifier = Modifier.height(14.dp),
        stroke = thickStroke,
        trackStroke = thickStroke,
    )
    Spacer(Modifier.requiredHeight(30.dp))
    Text("Set progress:")
    Slider(
        modifier = Modifier.width(300.dp),
        value = progress,
        valueRange = 0f..1f,
        onValueChange = { progress = it },

Material Expressive Theming refers to the customization of your Material Design app to better reflect your product’s brand.

Material components such as Button and Checkbox use values provided here when retrieving default values.

All values may be set by providing this component with the colorScheme, typography, shapes attributes. Use this to configure the overall theme of elements within this MaterialTheme.

Any values that are not set will fall back to the defaults. To inherit the current value from the theme, pass them into subsequent calls and override only the parts of the theme definition that need to change.

Alternatively, only call this function at the top of your application, and then call MaterialTheme to specify separate MaterialTheme(s) for different screens / parts of your UI, overriding only the parts of the theme definition that need to change.

Parameters
title: @Composable () -> Unit

the title to be displayed in the top app bar. This title will be used in the app bar's expanded and collapsed states, although in its collapsed state it will be composed with a smaller sized TextStyle
modifier: Modifier = Modifier

the Modifier to be applied to this top app bar
navigationIcon: @Composable () -> Unit = {}

the navigation icon displayed at the start of the top app bar. This should typically be an IconButton or IconToggleButton.
actions: @Composable RowScope.() -> Unit = {}

the actions displayed at the end of the top app bar. This should typically be IconButtons. The default layout here is a Row, so icons inside will be placed horizontally.
collapsedHeight: Dp = TopAppBarDefaults.MediumAppBarCollapsedHeight

this app bar height when collapsed by a provided scrollBehavior. This value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.MediumAppBarCollapsedHeight.
expandedHeight: Dp = TopAppBarDefaults.MediumAppBarExpandedHeight

this app bar's maximum height. When a specified scrollBehavior causes the app bar to collapse or expand, this value will represent the maximum height that the app-bar will be allowed to expand. The expanded height is expected to be greater or equal to the collapsedHeight, and the function will throw an IllegalArgumentException otherwise. Also, this value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.MediumAppBarExpandedHeight.
windowInsets: WindowInsets = TopAppBarDefaults.windowInsets

a window insets that app bar will respect.
colors: TopAppBarColors = TopAppBarDefaults.mediumTopAppBarColors()

TopAppBarColors that will be used to resolve the colors used for this top app bar in different states. See TopAppBarDefaults.mediumTopAppBarColors.
scrollBehavior: TopAppBarScrollBehavior? = null

a TopAppBarScrollBehavior which holds various offset values that will be applied by this top app bar to set up its height and colors. A scroll behavior is designed to work in conjunction with a scrolled content to change the top app bar appearance as the content scrolls. See TopAppBarScrollBehavior.nestedScrollConnection.
Throws
kotlin.IllegalArgumentException

if the provided expandedHeight is smaller than the collapsedHeight

Material Design modal bottom sheet.

Modal bottom sheets are used as an alternative to inline menus or simple dialogs on mobile, especially when offering a long list of action items, or when items require longer descriptions and icons. Like dialogs, modal bottom sheets appear in front of app content, disabling all other app functionality when they appear, and remaining on screen until confirmed, dismissed, or a required action has been taken.

Parameters
onDismissRequest: () -> Unit

Executes when the user clicks outside of the bottom sheet, after sheet animates to Hidden.
modifier: Modifier = Modifier

Optional Modifier for the bottom sheet.
sheetState: SheetState = rememberModalBottomSheetState()

The state of the bottom sheet.
sheetMaxWidth: Dp = BottomSheetDefaults.SheetMaxWidth

Dp that defines what the maximum width the sheet will take. Pass in Dp.Unspecified for a sheet that spans the entire screen width.
sheetGesturesEnabled: Boolean = true

    gesturesEnabled: Boolean = true,
    scrimColor: Color = DrawerDefaults.scrimColor,
    content: @Composable () -> Unit
): Unit

Material Design navigation drawer.

Navigation drawers provide ergonomic access to destinations in an app.

Modal navigation drawers block interaction with the rest of an app’s content with a scrim. They are elevated above most of the app’s UI and don’t affect the screen’s layout grid.

Material design modal wide navigation rail.

Wide navigation rails provide access to primary destinations in apps when using tablet and desktop screens.

The modal wide navigation rail should be used to display multiple WideNavigationRailItems, each representing a singular app destination, and, optionally, a header containing a menu button, a FloatingActionButton, and/or a logo. Each destination is typically represented by an icon and a text label.

The ModalWideNavigationRail when collapsed behaves like a collapsed WideNavigationRail. When expanded, the modal wide navigation rail blocks interaction with the rest of an app’s content with a scrim. It is elevated above the app’s UI and doesn't affect the screen’s layout grid. That can be achieved like so:

Material Design bottom navigation bar.

Navigation bars offer a persistent and convenient way to switch between primary destinations in an app.

![Navigation bar

  • image](https://developer.android.com/images/reference/androidx/compose/material3/navigation-bar.png)

NavigationBar should contain three to five NavigationBarItems, each representing a singular destination.

A simple example looks like:

import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material.icons.filled.Home
import androidx.compose.material.icons.filled.Star
import androidx.compose.material.icons.outlined.FavoriteBorder
import androidx.compose.material.icons.outlined.Home
import androidx.compose.material.icons.outlined.StarBorder
import androidx.compose.material3.Icon
import androidx.compose.material3.NavigationBar
import androidx.compose.material3.NavigationBarItem
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableIntStateOf
import androidx.compose.runtime.remember

var selectedItem by remember { mutableIntStateOf(0) }
val items = listOf("Songs", "Artists", "Playlists")
val selectedIcons = listOf(Icons.Filled.Home, Icons.Filled.Favorite, Icons.Filled.Star)
val unselectedIcons =
    listOf(Icons.Outlined.Home, Icons.Outlined.FavoriteBorder, Icons.Outlined.StarBorder)

NavigationBar {
    items.forEachIndexed { index, item ->
        NavigationBarItem(
            icon = {
                Icon(
                    if (selectedItem == index) selectedIcons[index] else unselectedIcons[index],
                    contentDescription = item
                )
            },
            label = { Text(item) },
            selected = selectedItem == index,
            onClick = { selectedItem = index }
        )
    }
}

See NavigationBarItem for configuration specific to each item, and not the overall NavigationBar component.

Parameters
modifier: Modifier = Modifier

the Modifier to be applied to this navigation bar
containerColor: Color = NavigationBarDefaults.containerColor

the color used for the background of this navigation bar. Use Color.Transparent to have no color.
contentColor: Color = MaterialTheme.colorScheme.contentColorFor(containerColor)

the preferred color for content inside this navigation bar. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
tonalElevation: Dp = NavigationBarDefaults.Elevation

when containerColor is ColorScheme.surface, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: Surface.
windowInsets: WindowInsets = NavigationBarDefaults.windowInsets

a window insets of the navigation bar.
content: @Composable RowScope.() -> Unit

the content of this navigation bar, typically 3-5 NavigationBarItems

The navigation rail should be used to display three to seven app destinations and, optionally, a FloatingActionButton or a logo header. Each destination is typically represented by an icon and an optional text label.

NavigationRail should contain multiple NavigationRailItems, each representing a singular destination.

A simple example looks like:

import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material.icons.filled.Home
import androidx.compose.material.icons.filled.Star
import androidx.compose.material.icons.outlined.FavoriteBorder
import androidx.compose.material.icons.outlined.Home
import androidx.compose.material.icons.outlined.StarBorder
import androidx.compose.material3.Icon
import androidx.compose.material3.NavigationRail
import androidx.compose.material3.NavigationRailItem
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableIntStateOf
import androidx.compose.runtime.remember

var selectedItem by remember { mutableIntStateOf(0) }
val items = listOf("Home", "Search", "Settings")
val selectedIcons = listOf(Icons.Filled.Home, Icons.Filled.Favorite, Icons.Filled.Star)
val unselectedIcons =
    listOf(Icons.Outlined.Home, Icons.Outlined.FavoriteBorder, Icons.Outlined.StarBorder)
NavigationRail {
    items.forEachIndexed { index, item ->
        NavigationRailItem(
            icon = {
                Icon(
                    if (selectedItem == index) selectedIcons[index] else unselectedIcons[index],
                    contentDescription = item
                )
            },
            label = { Text(item) },
            selected = selectedItem == index,
            onClick = { selectedItem = index }
        )
    }
}

See NavigationRailItem for configuration specific to each item, and not the overall NavigationRail component.

Parameters
modifier: Modifier = Modifier

the Modifier to be applied to this navigation rail
containerColor: Color = NavigationRailDefaults.ContainerColor

the color used for the background of this navigation rail. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(containerColor)

the preferred color for content inside this navigation rail. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
header: (@Composable ColumnScope.() -> Unit)? = null

optional header that may hold a FloatingActionButton or a logo
windowInsets: WindowInsets = NavigationRailDefaults.windowInsets

a window insets of the navigation rail.
content: @Composable ColumnScope.() -> Unit

Material Design navigation rail item.

A NavigationRailItem represents a destination within a NavigationRail.

Navigation rails provide access to primary destinations in apps when using tablet and desktop screens.

The text label is always shown (if it exists) when selected. Showing text labels if not selected is controlled by alwaysShowLabel.

Parameters
selected: Boolean

whether this item is selected
onClick: () -> Unit

called when this item is clicked
icon: @Composable () -> Unit

icon for this item, typically an Icon
modifier: Modifier = Modifier

the Modifier to be applied to this item
enabled: Boolean = true

controls the enabled state of this item. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
label: (@Composable () -> Unit)? = null

optional text label for this item
alwaysShowLabel: Boolean = true

whether to always show the label for this item. If false, the label will only be shown when this item is selected.
colors: NavigationRailItemColors = NavigationRailItemDefaults.colors()

NavigationRailItemColors that will be used to resolve the colors used for this item in different states. See NavigationRailItemDefaults.colors.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this item. You can use this to change the item's appearance or preview the item in different states. Note that if null is provided, interactions will still happen internally.

    contentPadding: PaddingValues = ButtonDefaults.ContentPadding,
    interactionSource: MutableInteractionSource? = null,
    content: @Composable RowScope.() -> Unit
): Unit

Material Design outlined button.

Buttons help people initiate actions, from sending an email, to sharing a document, to liking a post.

![Outlined button

  • image](https://developer.android.com/images/reference/androidx/compose/material3/outlined-button.png)

Outlined buttons are medium-emphasis buttons. They contain actions that are important, but are not the primary action in an app. Outlined buttons pair well with Buttons to indicate an alternative, secondary action.

import androidx.compose.material3.Button
import androidx.compose.material3.OutlinedButton
import androidx.compose.material3.Text

OutlinedButton(onClick = { /* Do something! */ }) { Text("Outlined Button") }

Choose the best button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

The default text style for internal Text components will be set to Typography.labelLarge.

Parameters
onClick: () -> Unit

called when this button is clicked
modifier: Modifier = Modifier

the Modifier to be applied to this button
enabled: Boolean = true

controls the enabled state of this button. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
shape: Shape = ButtonDefaults.outlinedShape

defines the shape of this button's container, border (when border is not null), and shadow (when using elevation).
colors: ButtonColors = ButtonDefaults.outlinedButtonColors()

ButtonColors that will be used to resolve the colors for this button in different states. See ButtonDefaults.outlinedButtonColors.
elevation: ButtonElevation? = null

ButtonElevation used to resolve the elevation for this button in different states. This controls the size of the shadow below the button. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay.
border: BorderStroke? = ButtonDefaults.outlinedButtonBorder(enabled)

the border to draw around the container of this button. Pass null for no border.
contentPadding: PaddingValues = ButtonDefaults.ContentPadding

the spacing values to apply internally between the container and the content
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this button. You can use this to change the button's appearance or preview the button in different states. Note that if null is provided, interactions will still happen internally.
content: @Composable RowScope.() -> Unit

The content displayed on the button, expected to be text, icon or image.

Icon buttons help people take supplementary actions with a single tap. They’re used when a compact button is required, such as in a toolbar or image list.

Use this "contained" icon button when the component requires more visual separation from the background.

content should typically be an Icon (see androidx.compose.material.icons.Icons). If using a custom icon, note that the typical size for the internal icon is 24 x 24 dp. The outlined icon button has an overall minimum touch target size of 48 x 48dp, to meet accessibility guidelines.

    colors: TextFieldColors = OutlinedTextFieldDefaults.colors(),
    contentPadding: PaddingValues = OutlinedTextFieldDefaults.contentPadding(),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design outlined text field for secure content.

Text fields allow users to enter text into a UI. OutlinedSecureTextField is specifically designed for password entry fields. It only supports a single line of content and comes with default settings that are appropriate for entering secure content. Additionally, some context menu actions like cut, copy, and drag are disabled for added security.

Outlined text fields have less visual emphasis than filled text fields. When they appear in places like forms, where many text fields are placed together, their reduced emphasis helps simplify the layout. For a filled version, see SecureTextField.

Parameters
state: TextFieldState

TextFieldState object that holds the internal editing state of the text field.
modifier: Modifier = Modifier

the Modifier to be applied to this text field.
enabled: Boolean = true

controls the enabled state of this text field. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
textStyle: TextStyle = LocalTextStyle.current

the style to be applied to the input text. Defaults to LocalTextStyle.
labelPosition: TextFieldLabelPosition = TextFieldLabelPosition.Attached()

the position of the label. See TextFieldLabelPosition.
label: (@Composable TextFieldLabelScope.() -> Unit)? = null

the optional label to be displayed with this text field. The default text style uses Typography.bodySmall when minimized and Typography.bodyLarge when expanded.
placeholder: (@Composable () -> Unit)? = null

the optional placeholder to be displayed when the input text is empty. The default text style uses Typography.bodyLarge.
leadingIcon: (@Composable () -> Unit)? = null

the optional leading icon to be displayed at the beginning of the text field container.
trailingIcon: (@Composable () -> Unit)? = null

the optional trailing icon to be displayed at the end of the text field container.
prefix: (@Composable () -> Unit)? = null

the optional prefix to be displayed before the input text in the text field.
suffix: (@Composable () -> Unit)? = null

the optional suffix to be displayed after the input text in the text field.
supportingText: (@Composable () -> Unit)? = null

the optional supporting text to be displayed below the text field.
isError: Boolean = false

indicates if the text field's current value is in error. When true, the components of the text field will be displayed in an error color, and an error will be announced to accessibility services.
inputTransformation: InputTransformation? = null

optional InputTransformation that will be used to transform changes to the TextFieldState made by the user. The transformation will be applied to changes made by hardware and software keyboard events, pasting or dropping text, accessibility services, and tests. The transformation will not be applied when changing the state programmatically, or when the transformation is changed. If the transformation is changed on an existing text field, it will be applied to the next user edit. The transformation will not immediately affect the current state.
textObfuscationMode: TextObfuscationMode = TextObfuscationMode.RevealLastTyped

the method used to obscure the input text.
textObfuscationCharacter: Char = DefaultObfuscationCharacter

the character to use while obfuscating the text. It doesn't have an effect when textObfuscationMode is set to TextObfuscationMode.Visible.
keyboardOptions: KeyboardOptions = SecureTextFieldKeyboardOptions

software keyboard options that contains configuration such as KeyboardType and ImeAction. This component by default configures KeyboardOptions for a secure text field by disabling auto correct and setting KeyboardType to KeyboardType.Password.
onKeyboardAction: KeyboardActionHandler? = null

called when the user presses the action button in the input method editor (IME), or by pressing the enter key on a hardware keyboard. By default this parameter is null, and would execute the default behavior for a received IME Action e.g., ImeAction.Done would close the keyboard, ImeAction.Next would switch the focus to the next focusable item on the screen.
onTextLayout: (Density.(getResult: () -> TextLayoutResult) -> Unit)? = null

Callback that is executed when the text layout becomes queryable. The callback receives a function that returns a TextLayoutResult if the layout can be calculated, or null if it cannot. The function reads the layout result from a snapshot state object, and will invalidate its caller when the layout result changes. A TextLayoutResult object contains paragraph information, size of the text, baselines and other details. Density scope is the one that was used while creating the given text layout.
shape: Shape = OutlinedTextFieldDefaults.shape

defines the shape of this text field's container.
colors: TextFieldColors = OutlinedTextFieldDefaults.colors()

TextFieldColors that will be used to resolve the colors used for this text field in different states. See TextFieldDefaults.colors.
contentPadding: PaddingValues = OutlinedTextFieldDefaults.contentPadding()

the padding applied to the inner text field that separates it from the surrounding elements of the text field. Note that the padding values may not be respected if they are incompatible with the text field's size constraints or layout. See TextFieldDefaults.contentPaddingWithLabel and TextFieldDefaults.contentPaddingWithoutLabel.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this text field. You can use this to change the text field's appearance or preview the text field in different states. Note that if null is provided, interactions will still happen internally.

Material Design outlined text field.

Text fields allow users to enter text into a UI. They typically appear in forms and dialogs. Outlined text fields have less visual emphasis than filled text fields. When they appear in places like forms, where many text fields are placed together, their reduced emphasis helps simplify the layout.

![Outlined text field

If apart from input text change you also want to observe the cursor location, selection range, or IME composition use the OutlinedTextField overload with the TextFieldValue parameter instead.

Parameters
value: String

the input text to be shown in the text field
onValueChange: (String) -> Unit

the callback that is triggered when the input service updates the text. An updated text comes as a parameter of the callback
modifier: Modifier = Modifier

the Modifier to be applied to this text field
enabled: Boolean = true

controls the enabled state of this text field. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
readOnly: Boolean = false

controls the editable state of the text field. When true, the text field cannot be modified. However, a user can focus it and copy text from it. Read-only text fields are usually used to display pre-filled forms that a user cannot edit.
textStyle: TextStyle = LocalTextStyle.current

the style to be applied to the input text. Defaults to LocalTextStyle.
label: (@Composable () -> Unit)? = null

the optional label to be displayed with this text field. The default text style uses Typography.bodySmall when minimized and Typography.bodyLarge when expanded.
placeholder: (@Composable () -> Unit)? = null

the optional placeholder to be displayed when the text field is in focus and the input text is empty. The default text style for internal Text is Typography.bodyLarge
leadingIcon: (@Composable () -> Unit)? = null

the optional leading icon to be displayed at the beginning of the text field container
trailingIcon: (@Composable () -> Unit)? = null

the optional trailing icon to be displayed at the end of the text field container
prefix: (@Composable () -> Unit)? = null

the optional prefix to be displayed before the input text in the text field
suffix: (@Composable () -> Unit)? = null

the optional suffix to be displayed after the input text in the text field
supportingText: (@Composable () -> Unit)? = null

the optional supporting text to be displayed below the text field
isError: Boolean = false

indicates if the text field's current value is in error. If set to true, the label, bottom indicator and trailing icon by default will be displayed in error color
visualTransformation: VisualTransformation = VisualTransformation.None

transforms the visual representation of the input value For example, you can use PasswordVisualTransformation to create a password text field. By default, no visual transformation is applied.
keyboardOptions: KeyboardOptions = KeyboardOptions.Default

software keyboard options that contains configuration such as KeyboardType and ImeAction
keyboardActions: KeyboardActions = KeyboardActions.Default

when the input service emits an IME action, the corresponding callback is called. Note that this IME action may be different from what you specified in KeyboardOptions.imeAction
singleLine: Boolean = false

when true, this text field becomes a single horizontally scrolling text field instead of wrapping onto multiple lines. The keyboard will be informed to not show the return key as the ImeAction. Note that maxLines parameter will be ignored as the maxLines attribute will be automatically set to 1.
maxLines: Int = if (singleLine) 1 else Int.MAX_VALUE

the maximum height in terms of maximum number of visible lines. It is required that 1 <= minLines<= maxLines. This parameter is ignored when singleLine is true.
minLines: Int = 1

the minimum height in terms of minimum number of visible lines. It is required that 1 <= minLines<= maxLines. This parameter is ignored when singleLine is true.
interactionSource: MutableInteractionSource? = null

If you are looking for a filled version, see TextField. For a text field specifically designed for passwords or other secure content, see OutlinedSecureTextField.

This overload of OutlinedTextField uses TextFieldState to keep track of its text content and position of the cursor or selection.

See example usage:

import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.OutlinedTextField

    state = rememberTextFieldState(),
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
)

val state = rememberTextFieldState("Initial text", TextRange(0, 12))
OutlinedTextField(
    state = state,
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
)
Parameters
state: TextFieldState

TextFieldState object that holds the internal editing state of the text field.
modifier: Modifier = Modifier

the Modifier to be applied to this text field.
enabled: Boolean = true

controls the enabled state of this text field. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
readOnly: Boolean = false

controls the editable state of the text field. When true, the text field cannot be modified. However, a user can focus it and copy text from it. Read-only text fields are usually used to display pre-filled forms that a user cannot edit.
textStyle: TextStyle = LocalTextStyle.current

the style to be applied to the input text. Defaults to LocalTextStyle.
labelPosition: TextFieldLabelPosition = TextFieldLabelPosition.Attached()

the position of the label. See TextFieldLabelPosition.
label: (@Composable TextFieldLabelScope.() -> Unit)? = null

the optional label to be displayed with this text field. The default text style uses Typography.bodySmall when minimized and Typography.bodyLarge when expanded.
placeholder: (@Composable () -> Unit)? = null

the optional placeholder to be displayed when the input text is empty. The default text style uses Typography.bodyLarge.
leadingIcon: (@Composable () -> Unit)? = null

the optional leading icon to be displayed at the beginning of the text field container.
trailingIcon: (@Composable () -> Unit)? = null

the optional trailing icon to be displayed at the end of the text field container.
prefix: (@Composable () -> Unit)? = null

the optional prefix to be displayed before the input text in the text field.
suffix: (@Composable () -> Unit)? = null

the optional suffix to be displayed after the input text in the text field.
supportingText: (@Composable () -> Unit)? = null

the optional supporting text to be displayed below the text field.
isError: Boolean = false

indicates if the text field's current value is in error. When true, the components of the text field will be displayed in an error color, and an error will be announced to accessibility services.
inputTransformation: InputTransformation? = null

optional InputTransformation that will be used to transform changes to the TextFieldState made by the user. The transformation will be applied to changes made by hardware and software keyboard events, pasting or dropping text, accessibility services, and tests. The transformation will not be applied when changing the state programmatically, or when the transformation is changed. If the transformation is changed on an existing text field, it will be applied to the next user edit. The transformation will not immediately affect the current state.
outputTransformation: OutputTransformation? = null

optional OutputTransformation that transforms how the contents of the text field are presented.
keyboardOptions: KeyboardOptions = KeyboardOptions.Default

software keyboard options that contains configuration such as KeyboardType and ImeAction.
onKeyboardAction: KeyboardActionHandler? = null

called when the user presses the action button in the input method editor (IME), or by pressing the enter key on a hardware keyboard. By default this parameter is null, and would execute the default behavior for a received IME Action e.g., ImeAction.Done would close the keyboard, ImeAction.Next would switch the focus to the next focusable item on the screen.
lineLimits: TextFieldLineLimits = TextFieldLineLimits.Default

whether the text field should be SingleLine, scroll horizontally, and ignore newlines; or MultiLine and grow and scroll vertically. If SingleLine is passed, all newline characters ('\n') within the text will be replaced with regular whitespace (' ').
onTextLayout: (Density.(getResult: () -> TextLayoutResult) -> Unit)? = null

Callback that is executed when the text layout becomes queryable. The callback receives a function that returns a TextLayoutResult if the layout can be calculated, or null if it cannot. The function reads the layout result from a snapshot state object, and will invalidate its caller when the layout result changes. A TextLayoutResult object contains paragraph information, size of the text, baselines and other details. Density scope is the one that was used while creating the given text layout.
scrollState: ScrollState = rememberScrollState()

scroll state that manages either horizontal or vertical scroll of the text field. If lineLimits is SingleLine, this text field is treated as single line with horizontal scroll behavior. Otherwise, the text field becomes vertically scrollable.
shape: Shape = OutlinedTextFieldDefaults.shape

defines the shape of this text field's border.
colors: TextFieldColors = OutlinedTextFieldDefaults.colors()

TextFieldColors that will be used to resolve the colors used for this text field in different states. See OutlinedTextFieldDefaults.colors.
contentPadding: PaddingValues = OutlinedTextFieldDefaults.contentPadding()

the padding applied to the inner text field that separates it from the surrounding elements of the text field. Note that the padding values may not be respected if they are incompatible with the text field's size constraints or layout. See OutlinedTextFieldDefaults.contentPadding.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this text field. You can use this to change the text field's appearance or preview the text field in different states. Note that if null is provided, interactions will still happen internally.

    content: @Composable RowScope.() -> Unit
): Unit

TODO link to mio page when available.

Toggle button is a toggleable button that switches between primary and tonal colors depending on checked's value. It also morphs between the three shapes provided in shapes depending on the state of the interaction with the toggle button as long as the three shapes provided our CornerBasedShapes. If a shape in shapes isn't a CornerBasedShape, then toggle button will toggle between the ButtonShapes according to user interaction.

TODO link to an image when available

Outlined toggle buttons are medium-emphasis buttons. They contain actions that are important, but are not the primary action in an app. Outlined buttons pair well with ToggleButtons to indicate an alternative, secondary action.

see OutlinedButton for a static button that doesn't need to be toggled. see OutlinedIconToggleButton for a toggleable button where the content is specifically an Icon.

        },
    divider: @Composable () -> Unit = @Composable { HorizontalDivider() },
    tabs: @Composable () -> Unit
): Unit

Material Design Scrollable Primary tabs

Primary tabs are placed at the top of the content pane under a top app bar. They display the main content destinations. When a set of tabs cannot fit on screen, use scrollable tabs. Scrollable tabs can use longer text labels and a larger number of tabs. They are best used for browsing on touch interfaces.

A scrollable tab row contains a row of Tabs, and displays an indicator underneath the currently selected tab. A scrollable tab row places its tabs offset from the starting edge, and allows scrolling to tabs that are placed off screen. For a fixed tab row that does not allow scrolling, and evenly places its tabs, see PrimaryTabRow.

Parameters
selectedTabIndex: Int

the index of the currently selected tab
modifier: Modifier = Modifier

the Modifier to be applied to this tab row
scrollState: ScrollState = rememberScrollState()

the ScrollState of this tab row
containerColor: Color = TabRowDefaults.primaryContainerColor

the color used for the background of this tab row. Use Color.Transparent to have no color.
contentColor: Color = TabRowDefaults.primaryContentColor

the preferred color for content inside this tab row. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
edgePadding: Dp = TabRowDefaults.ScrollableTabRowEdgeStartPadding

the padding between the starting and ending edge of the scrollable tab row, and the tabs inside the row. This padding helps inform the user that this tab row can be scrolled, unlike a TabRow.
indicator: @Composable TabIndicatorScope.() -> Unit = @Composable { TabRowDefaults.PrimaryIndicator( Modifier.tabIndicatorOffset(selectedTabIndex, matchContentSize = true), width = Dp.Unspecified, ) }

the indicator that represents which tab is currently selected. By default this will be a TabRowDefaults.PrimaryIndicator, using a TabRowDefaults.tabIndicatorOffset modifier to animate its position.
divider: @Composable () -> Unit = @Composable { HorizontalDivider() }

the divider displayed at the bottom of the tab row. This provides a layer of separation between the tab row and the content displayed underneath.
tabs: @Composable () -> Unit

the tabs inside this tab row. Typically this will be multiple Tabs. Each element inside this lambda will be measured and placed evenly across the row, each taking up equal space.

PrimaryTabRow

@ExperimentalMaterial3Api
@Composable
fun PrimaryTabRow(
    selectedTabIndex: Int,
    modifier: Modifier = Modifier,
    containerColor: Color = TabRowDefaults.primaryContainerColor,
    contentColor: Color = TabRowDefaults.primaryContentColor,
    indicator: @Composable TabIndicatorScope.() -> Unit = {

Material Design Fixed Primary tabs

Primary tabs are placed at the top of the content pane under a top app bar. They display the main content destinations. Fixed tabs display all tabs in a set simultaneously. They are best for switching between related content quickly, such as between transportation methods in a map. To navigate between fixed tabs, tap an individual tab, or swipe left or right in the content area.

A TabRow contains a row of Tabs, and displays an indicator underneath the currently selected tab. A TabRow places its tabs evenly spaced along the entire row, with each tab taking up an equal amount of space. See PrimaryScrollableTabRow for a tab row that does not enforce equal size, and allows scrolling to tabs that do not fit on screen.

A simple example with text tabs looks like:

import androidx.compose.foundation.layout.Column
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.PrimaryTabRow
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.text.style.TextOverflow

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3 with lots of text")
Column {
    PrimaryTabRow(selectedTabIndex = state) {
        titles.forEachIndexed { index, title ->
            Tab(
                selected = state == index,
                onClick = { state = index },
                text = { Text(text = title, maxLines = 2, overflow = TextOverflow.Ellipsis) }
            )
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Primary tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}

You can also provide your own custom tab, such as:

import androidx.compose.foundation.layout.Column
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.SecondaryTabRow
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3")
Column {
    SecondaryTabRow(selectedTabIndex = state) {
        titles.forEachIndexed { index, title ->
            FancyTab(title = title, onClick = { state = index }, selected = (index == state))
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Fancy tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}

Where the custom tab itself could look like:

import androidx.compose.foundation.background
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.layout.size
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

Tab(selected, onClick) {
    Column(
        Modifier.padding(10.dp).height(50.dp).fillMaxWidth(),
        verticalArrangement = Arrangement.SpaceBetween
    ) {
        Box(
            Modifier.size(10.dp)
                .align(Alignment.CenterHorizontally)
                .background(
                    color =
                        if (selected) MaterialTheme.colorScheme.primary
                        else MaterialTheme.colorScheme.background
                )
        )
        Text(
            text = title,
            style = MaterialTheme.typography.bodyLarge,
            modifier = Modifier.align(Alignment.CenterHorizontally)
        )
    }
}

As well as customizing the tab, you can also provide a custom indicator, to customize the indicator displayed for a tab. indicator will be placed to fill the entire TabRow, so it should internally take care of sizing and positioning the indicator to match changes to selectedTabIndex.

For example, given an indicator that draws a rounded rectangle near the edges of the Tab:

import androidx.compose.foundation.BorderStroke
import androidx.compose.foundation.border
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.shape.RoundedCornerShape
import androidx.compose.material3.Tab
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.graphics.drawscope.Stroke
import androidx.compose.ui.unit.dp

// Draws a rounded rectangular with border around the Tab, with a 5.dp padding from the edges
// Color is passed in as a parameter [color]
Box(
    modifier
        .padding(5.dp)
        .fillMaxSize()
        .border(BorderStroke(2.dp, color), RoundedCornerShape(5.dp))
)

We can reuse TabRowDefaults.tabIndicatorOffset and just provide this indicator, as we aren't changing how the size and position of the indicator changes between tabs:

import androidx.compose.foundation.layout.Column
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.SecondaryTabRow
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3")

Column {
    SecondaryTabRow(
        selectedTabIndex = state,
        indicator = {
            FancyIndicator(
                MaterialTheme.colorScheme.primary,
                Modifier.tabIndicatorOffset(state)
            )
        }
    ) {
        titles.forEachIndexed { index, title ->
            Tab(selected = state == index, onClick = { state = index }, text = { Text(title) })
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Fancy indicator tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}

You may also want to use a custom transition, to allow you to dynamically change the appearance of the indicator as it animates between tabs, such as changing its color or size. indicator is stacked on top of the entire TabRow, so you just need to provide a custom transition that animates the offset of the indicator from the start of the TabRow. For example, take the following example that uses a transition to animate the offset, width, and color of the same FancyIndicator from before, also adding a physics based 'spring' effect to the indicator in the direction of motion:

import androidx.compose.animation.animateColorAsState
import androidx.compose.animation.core.Animatable

                            if (startAnim.targetValue < newStart) {

    }
    Text(

        text = "Fancy transition tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}
Parameters

the preferred color for content inside this tab row. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
indicator: @Composable TabIndicatorScope.() -> Unit = { TabRowDefaults.PrimaryIndicator( modifier = Modifier.tabIndicatorOffset(selectedTabIndex, matchContentSize = true), width = Dp.Unspecified, ) }

the indicator that represents which tab is currently selected. By default this will be a TabRowDefaults.PrimaryIndicator, using a TabRowDefaults.tabIndicatorOffset modifier to animate its position.
divider: @Composable () -> Unit = @Composable { HorizontalDivider() }

the divider displayed at the bottom of the tab row. This provides a layer of separation between the tab row and the content displayed underneath.

}
Parameters
selected: Boolean

whether this radio button is selected or not
onClick: (() -> Unit)?

called when this radio button is clicked. If null, then this radio button will not be interactable, unless something else handles its input events and updates its state.
modifier: Modifier = Modifier

the Modifier to be applied to this radio button
enabled: Boolean = true

controls the enabled state of this radio button. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
colors: RadioButtonColors = RadioButtonDefaults.colors()

RadioButtonColors that will be used to resolve the color used for this radio button in different states. See RadioButtonDefaults.colors.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this radio button. You can use this to change the radio button's appearance or preview the radio button in different states. Note that if null is provided, interactions will still happen internally.

RangeSlider

Cmn 
@Composable
fun RangeSlider(
    value: ClosedFloatingPointRange<Float>,
    onValueChange: (ClosedFloatingPointRange<Float>) -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    valueRange: ClosedFloatingPointRange<Float> = 0f..1f,
    steps: @IntRange(from = 0) Int = 0,
    onValueChangeFinished: (() -> Unit)? = null,
    colors: SliderColors = SliderDefaults.colors()
): Unit

Material Design Range slider.

Range Sliders expand upon Slider using the same concepts but allow the user to select 2 values.

The two values are still bounded by the value range but they also cannot cross each other.

Use continuous Range Sliders to allow users to make meaningful selections that don’t require a specific values:

import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.padding
import androidx.compose.material3.RangeSlider
import androidx.compose.material3.RangeSliderState
import androidx.compose.material3.Slider
import androidx.compose.material3.SliderState
import androidx.compose.material3.Text
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.semantics.contentDescription
import androidx.compose.ui.semantics.semantics
import androidx.compose.ui.unit.dp

val rangeSliderState = remember {
    RangeSliderState(
        0f,
        100f,
        valueRange = 0f..100f,
        onValueChangeFinished = {
            // launch some business logic update with the state you hold
            // viewModel.updateSelectedSliderValue(sliderPosition)
        }
    )
}
Column(modifier = Modifier.padding(horizontal = 16.dp)) {
    val rangeStart = "%.2f".format(rangeSliderState.activeRangeStart)
    val rangeEnd = "%.2f".format(rangeSliderState.activeRangeEnd)
    Text(text = "$rangeStart .. $rangeEnd")
    RangeSlider(
        state = rangeSliderState,
        modifier = Modifier.semantics { contentDescription = "Localized Description" }
    )
}

You can allow the user to choose only between predefined set of values by specifying the amount of steps between min and max values:

Parameters
value: ClosedFloatingPointRange<Float>

current values of the RangeSlider. If either value is outside of valueRange provided, it will be coerced to this range.
onValueChange: (ClosedFloatingPointRange<Float>) -> Unit

lambda in which values should be updated
modifier: Modifier = Modifier

modifiers for the Range Slider layout
enabled: Boolean = true

whether or not component is enabled and can we interacted with or not
valueRange: ClosedFloatingPointRange<Float> = 0f..1f

range of values that Range Slider values can take. Passed value will be coerced to this range
steps: @IntRange(from = 0) Int = 0

if positive, specifies the amount of discrete allowable values (in addition to the endpoints of the value range). Step values are evenly distributed across the range. If 0, the range slider will behave continuously and allow any value from the range. Must not be negative.
onValueChangeFinished: (() -> Unit)? = null

lambda to be invoked when value change has ended. This callback shouldn't be used to update the range slider values (use onValueChange for that), but rather to know when the user has completed selecting a new value by ending a drag or a click.
colors: SliderColors = SliderDefaults.colors()

SliderColors that will be used to determine the color of the Range Slider parts in different state. See SliderDefaults.colors to customize.

Material Design Range slider.

Range Sliders expand upon Slider using the same concepts but allow the user to select 2 values.

The two values are still bounded by the value range but they also cannot cross each other.

It uses the provided startThumb for the slider's start thumb and endThumb for the slider's end thumb. It also uses the provided track for the slider's track. If nothing is passed for these parameters, it will use SliderDefaults.Thumb and SliderDefaults.Track for the thumbs and track.

Use continuous Range Sliders to allow users to make meaningful selections that don’t require a specific values:

startThumb: @Composable (RangeSliderState) -> Unit = { SliderDefaults.Thumb( interactionSource = startInteractionSource, colors = colors, enabled = enabled ) }

the start thumb to be displayed on the Range Slider. The lambda receives a RangeSliderState which is used to obtain the current active track.
endThumb: @Composable (RangeSliderState) -> Unit = { SliderDefaults.Thumb( interactionSource = endInteractionSource, colors = colors, enabled = enabled ) }

the end thumb to be displayed on the Range Slider. The lambda receives a RangeSliderState which is used to obtain the current active track.
track: @Composable (RangeSliderState) -> Unit = { rangeSliderState -> SliderDefaults.Track( colors = colors, enabled = enabled, rangeSliderState = rangeSliderState ) }

the track to be displayed on the range slider, it is placed underneath the thumb. The lambda receives a RangeSliderState which is used to obtain the current active track.
steps: @IntRange(from = 0) Int = 0

if positive, specifies the amount of discrete allowable values (in addition to the endpoints of the value range). Step values are evenly distributed across the range. If 0, the range slider will behave continuously and allow any value from the range. Must not be negative.

Parameters
modifier: Modifier = Modifier

the Modifier to be applied to this scaffold
topBar: @Composable () -> Unit = {}

top app bar of the screen, typically a SmallTopAppBar
bottomBar: @Composable () -> Unit = {}

bottom bar of the screen, typically a NavigationBar
snackbarHost: @Composable () -> Unit = {}

component to host Snackbars that are pushed to be shown via SnackbarHostState.showSnackbar, typically a SnackbarHost
floatingActionButton: @Composable () -> Unit = {}

Main action button of the screen, typically a FloatingActionButton
floatingActionButtonPosition: FabPosition = FabPosition.End

position of the FAB on the screen. See FabPosition.
containerColor: Color = MaterialTheme.colorScheme.background

the color used for the background of this scaffold. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(containerColor)

the preferred color for content inside this scaffold. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
contentWindowInsets: WindowInsets = ScaffoldDefaults.contentWindowInsets

window insets to be passed to content slot via PaddingValues params. Scaffold will take the insets into account from the top/bottom only if the topBar/ bottomBar are not present, as the scaffold expect topBar/bottomBar to handle insets instead. Any insets consumed by other insets padding modifiers or consumeWindowInsets on a parent layout will be excluded from contentWindowInsets.
content: @Composable (PaddingValues) -> Unit

content of the screen. The lambda receives a PaddingValues that should be applied to the content root via Modifier.padding and Modifier.consumeWindowInsets to properly offset top and bottom bars. If using Modifier.verticalScroll, apply this modifier to the child of the scroll, and not on the scroll itself.

ScrollableTabRow

Cmn 
@Composable
fun ScrollableTabRow(
    selectedTabIndex: Int,
    modifier: Modifier = Modifier,
    containerColor: Color = TabRowDefaults.primaryContainerColor,
    contentColor: Color = TabRowDefaults.primaryContentColor,
    edgePadding: Dp = TabRowDefaults.ScrollableTabRowEdgeStartPadding,
    indicator: @Composable (tabPositions: List<TabPosition>) -> Unit = @Composable { tabPositions ->
            TabRowDefaults.SecondaryIndicator(
                Modifier.tabIndicatorOffset(tabPositions[selectedTabIndex])
            )
        },
    divider: @Composable () -> Unit = @Composable { HorizontalDivider() },
    tabs: @Composable () -> Unit
): Unit

Material Design tabs

Material Design scrollable tabs.

For primary indicator tabs, use PrimaryScrollableTabRow. For secondary indicator tabs, use SecondaryScrollableTabRow.

When a set of tabs cannot fit on screen, use scrollable tabs. Scrollable tabs can use longer text labels and a larger number of tabs. They are best used for browsing on touch interfaces.

A ScrollableTabRow contains a row of Tabs, and displays an indicator underneath the currently selected tab. A ScrollableTabRow places its tabs offset from the starting edge, and allows scrolling to tabs that are placed off screen. For a fixed tab row that does not allow scrolling, and evenly places its tabs, see TabRow.

Parameters
selectedTabIndex: Int

the index of the currently selected tab
modifier: Modifier = Modifier

the Modifier to be applied to this tab row
containerColor: Color = TabRowDefaults.primaryContainerColor

the color used for the background of this tab row. Use Color.Transparent to have no color.
contentColor: Color = TabRowDefaults.primaryContentColor

the preferred color for content inside this tab row. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
edgePadding: Dp = TabRowDefaults.ScrollableTabRowEdgeStartPadding

the padding between the starting and ending edge of the scrollable tab row, and the tabs inside the row. This padding helps inform the user that this tab row can be scrolled, unlike a TabRow.
indicator: @Composable (tabPositions: List<TabPosition>) -> Unit = @Composable { tabPositions -> TabRowDefaults.SecondaryIndicator( Modifier.tabIndicatorOffset(tabPositions[selectedTabIndex]) ) }

the indicator that represents which tab is currently selected. By default this will be a TabRowDefaults.SecondaryIndicator, using a TabRowDefaults.tabIndicatorOffset modifier to animate its position. Note that this indicator will be forced to fill up the entire tab row, so you should use TabRowDefaults.tabIndicatorOffset or similar to animate the actual drawn indicator inside this space, and provide an offset from the start.
divider: @Composable () -> Unit = @Composable { HorizontalDivider() }

the divider displayed at the bottom of the tab row. This provides a layer of separation between the tab row and the content displayed underneath.
tabs: @Composable () -> Unit

the tabs inside this tab row. Typically this will be multiple Tabs. Each element inside this lambda will be measured and placed evenly across the row, each taking up equal space.

    windowInsets: WindowInsets = SearchBarDefaults.windowInsets,
    content: @Composable ColumnScope.() -> Unit
): Unit

Material Design search.

A search bar represents a floating search field that allows users to enter a keyword or phrase and get relevant information. It can be used as a way to navigate through an app via search queries.

A search bar expands into a search "view" and can be used to display dynamic suggestions or search results.

![Search bar

  • image](https://developer.android.com/images/reference/androidx/compose/material3/search-bar.png)

A SearchBar tries to occupy the entirety of its allowed size in the expanded state. For full-screen behavior as specified by Material guidelines, parent layouts of the SearchBar must not pass any Constraints that limit its size, and the host activity should set WindowCompat.setDecorFitsSystemWindows(window, false).

If this expansion behavior is undesirable, for example on large tablet screens, DockedSearchBar can be used instead.

Material Design Scrollable Secondary tabs

Material Design scrollable tabs.

Secondary tabs are used within a content area to further separate related content and establish hierarchy. When a set of tabs cannot fit on screen, use scrollable tabs. Scrollable tabs can use longer text labels and a larger number of tabs. They are best used for browsing on touch interfaces.

A scrollable tab row contains a row of Tabs, and displays an indicator underneath the currently selected tab. A scrollable tab row places its tabs offset from the starting edge, and allows scrolling to tabs that are placed off screen. For a fixed tab row that does not allow scrolling, and evenly places its tabs, see SecondaryTabRow.

Parameters
selectedTabIndex: Int

the index of the currently selected tab
modifier: Modifier = Modifier

the Modifier to be applied to this tab row
scrollState: ScrollState = rememberScrollState()

the ScrollState of this tab row
containerColor: Color = TabRowDefaults.secondaryContainerColor

the color used for the background of this tab row. Use Color.Transparent to have no color.
contentColor: Color = TabRowDefaults.secondaryContentColor

the preferred color for content inside this tab row. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
edgePadding: Dp = TabRowDefaults.ScrollableTabRowEdgeStartPadding

the padding between the starting and ending edge of the scrollable tab row, and the tabs inside the row. This padding helps inform the user that this tab row can be scrolled, unlike a TabRow.
indicator: @Composable TabIndicatorScope.() -> Unit = @Composable { TabRowDefaults.SecondaryIndicator( Modifier.tabIndicatorOffset(selectedTabIndex, matchContentSize = false) ) }

the indicator that represents which tab is currently selected. By default this will be a TabRowDefaults.SecondaryIndicator, using a TabRowDefaults.tabIndicatorOffset modifier to animate its position. Note that this indicator will be forced to fill up the entire tab row, so you should use TabRowDefaults.tabIndicatorOffset or similar to animate the actual drawn indicator inside this space, and provide an offset from the start.
divider: @Composable () -> Unit = @Composable { HorizontalDivider() }

the divider displayed at the bottom of the tab row. This provides a layer of separation between the tab row and the content displayed underneath.
tabs: @Composable () -> Unit

the tabs inside this tab row. Typically this will be multiple Tabs. Each element inside this lambda will be measured and placed evenly across the row, each taking up equal space.

SecondaryTabRow

Cmn 
@ExperimentalMaterial3Api
@Composable
fun SecondaryTabRow(
    selectedTabIndex: Int,
    modifier: Modifier = Modifier,
    containerColor: Color = TabRowDefaults.secondaryContainerColor,
    contentColor: Color = TabRowDefaults.secondaryContentColor,
    indicator: @Composable TabIndicatorScope.() -> Unit = @Composable {
            TabRowDefaults.SecondaryIndicator(
                Modifier.tabIndicatorOffset(selectedTabIndex, matchContentSize = false)
            )
        },
    divider: @Composable () -> Unit = @Composable { HorizontalDivider() },
    tabs: @Composable () -> Unit
): Unit

Material Design Fixed Secondary tabs

Secondary tabs are used within a content area to further separate related content and establish hierarchy. Fixed tabs display all tabs in a set simultaneously. To navigate between fixed tabs, tap an individual tab, or swipe left or right in the content area.

A TabRow contains a row of Tabs, and displays an indicator underneath the currently selected tab. A Fixed TabRow places its tabs evenly spaced along the entire row, with each tab taking up an equal amount of space. See SecondaryScrollableTabRow for a tab row that does not enforce equal size, and allows scrolling to tabs that do not fit on screen.

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3 with lots of text")
Column {
    SecondaryTabRow(selectedTabIndex = state) {
        titles.forEachIndexed { index, title ->
            Tab(
                selected = state == index,
                onClick = { state = index },
                text = { Text(text = title, maxLines = 2, overflow = TextOverflow.Ellipsis) }
            )
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Secondary tab ${state + 1} selected",

indicator: @Composable TabIndicatorScope.() -> Unit = @Composable { TabRowDefaults.SecondaryIndicator( Modifier.tabIndicatorOffset(selectedTabIndex, matchContentSize = false) ) }

the indicator that represents which tab is currently selected. By default this will be a TabRowDefaults.SecondaryIndicator, using a TabRowDefaults.tabIndicatorOffset modifier to animate its position. Note that this indicator will be forced to fill up the entire tab row, so you should use TabRowDefaults.tabIndicatorOffset or similar to animate the actual drawn indicator inside this space, and provide an offset from the start.

    interactionSource: MutableInteractionSource? = null
): Unit

Material Design filled text field for secure content.

Text fields allow users to enter text into a UI. SecureTextField is specifically designed for password entry fields. It only supports a single line of content and comes with default settings that are appropriate for entering secure content. Additionally, some context menu actions like cut, copy, and drag are disabled for added security.

Filled text fields have more visual emphasis than outlined text fields, making them stand out when surrounded by other content and components. For an outlined version, see OutlinedSecureTextField.

Example of a password text field:

import androidx.compose.foundation.text.input.TextObfuscationMode
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Visibility
import androidx.compose.material.icons.filled.VisibilityOff
import androidx.compose.material3.Icon
import androidx.compose.material3.IconButton
import androidx.compose.material3.SecureTextField
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.runtime.saveable.rememberSaveable

var passwordHidden by rememberSaveable { mutableStateOf(true) }
SecureTextField(
    state = rememberTextFieldState(),
    label = { Text("Enter password") },
    textObfuscationMode =
        if (passwordHidden) TextObfuscationMode.RevealLastTyped
        else TextObfuscationMode.Visible,
    trailingIcon = {
        IconButton(onClick = { passwordHidden = !passwordHidden }) {
            val visibilityIcon =
                if (passwordHidden) Icons.Filled.Visibility else Icons.Filled.VisibilityOff
            // Provide localized description for accessibility services
            val description = if (passwordHidden) "Show password" else "Hide password"
            Icon(imageVector = visibilityIcon, contentDescription = description)
        }
    }
)

the optional supporting text to be displayed below the text field.
isError: Boolean = false

indicates if the text field's current value is in error. When true, the components of the text field will be displayed in an error color, and an error will be announced to accessibility services.
inputTransformation: InputTransformation? = null

optional InputTransformation that will be used to transform changes to the TextFieldState made by the user. The transformation will be applied to changes made by hardware and software keyboard events, pasting or dropping text, accessibility services, and tests. The transformation will not be applied when changing the state programmatically, or when the transformation is changed. If the transformation is changed on an existing text field, it will be applied to the next user edit. The transformation will not immediately affect the current state.
textObfuscationMode: TextObfuscationMode = TextObfuscationMode.RevealLastTyped

the method used to obscure the input text.
textObfuscationCharacter: Char = DefaultObfuscationCharacter

the character to use while obfuscating the text. It doesn't have an effect when textObfuscationMode is set to TextObfuscationMode.Visible.
keyboardOptions: KeyboardOptions = SecureTextFieldKeyboardOptions

software keyboard options that contains configuration such as KeyboardType and ImeAction. This component by default configures KeyboardOptions for a secure text field by disabling auto correct and setting KeyboardType to KeyboardType.Password.
onKeyboardAction: KeyboardActionHandler? = null

called when the user presses the action button in the input method editor (IME), or by pressing the enter key on a hardware keyboard. By default this parameter is null, and would execute the default behavior for a received IME Action e.g., ImeAction.Done would close the keyboard, ImeAction.Next would switch the focus to the next focusable item on the screen.
onTextLayout: (Density.(getResult: () -> TextLayoutResult) -> Unit)? = null

Callback that is executed when the text layout becomes queryable. The callback receives a function that returns a TextLayoutResult if the layout can be calculated, or null if it cannot. The function reads the layout result from a snapshot state object, and will invalidate its caller when the layout result changes. A TextLayoutResult object contains paragraph information, size of the text, baselines and other details. Density scope is the one that was used while creating the given text layout.
shape: Shape = TextFieldDefaults.shape

defines the shape of this text field's container.
colors: TextFieldColors = TextFieldDefaults.colors()

TextFieldColors that will be used to resolve the colors used for this text field in different states. See TextFieldDefaults.colors.
contentPadding: PaddingValues = if (label == null || labelPosition is TextFieldLabelPosition.Above) { TextFieldDefaults.contentPaddingWithoutLabel() } else { TextFieldDefaults.contentPaddingWithLabel() }

the padding applied to the inner text field that separates it from the surrounding elements of the text field. Note that the padding values may not be respected if they are incompatible with the text field's size constraints or layout. See TextFieldDefaults.contentPaddingWithLabel and TextFieldDefaults.contentPaddingWithoutLabel.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this text field. You can use this to change the text field's appearance or preview the text field in different states. Note that if null is provided, interactions will still happen internally.

ShortNavigationBar

Cmn 
@ExperimentalMaterial3ExpressiveApi
@Composable
fun ShortNavigationBar(
    modifier: Modifier = Modifier,
    containerColor: Color = ShortNavigationBarDefaults.containerColor,
    contentColor: Color = ShortNavigationBarDefaults.contentColor,
    windowInsets: WindowInsets = ShortNavigationBarDefaults.windowInsets,
    arrangement: ShortNavigationBarArrangement = ShortNavigationBarDefaults.arrangement,
    content: @Composable () -> Unit
): Unit

Material Design short navigation bar.

Short navigation bars offer a persistent and convenient way to switch between primary destinations in an app.

The recommended configuration of the ShortNavigationBar depends on the width size of the screen it's being displayed at:

A simple example of the first configuration looks like this:

import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material.icons.filled.Home
import androidx.compose.material.icons.filled.Star
import androidx.compose.material.icons.outlined.FavoriteBorder
import androidx.compose.material.icons.outlined.Home
import androidx.compose.material.icons.outlined.StarBorder
import androidx.compose.material3.Icon
import androidx.compose.material3.NavigationBar
import androidx.compose.material3.NavigationBarItem
import androidx.compose.material3.ShortNavigationBar
import androidx.compose.material3.ShortNavigationBarItem
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableIntStateOf
import androidx.compose.runtime.remember

var selectedItem by remember { mutableIntStateOf(0) }
val items = listOf("Songs", "Artists", "Playlists")
val selectedIcons = listOf(Icons.Filled.Home, Icons.Filled.Favorite, Icons.Filled.Star)
val unselectedIcons =
    listOf(Icons.Outlined.Home, Icons.Outlined.FavoriteBorder, Icons.Outlined.StarBorder)

ShortNavigationBar {
    items.forEachIndexed { index, item ->
        ShortNavigationBarItem(
            icon = {
                Icon(
                    if (selectedItem == index) selectedIcons[index] else unselectedIcons[index],
                    contentDescription = null
                )
            },
            label = { Text(item) },
            selected = selectedItem == index,
            onClick = { selectedItem = index }
        )
    }
}

And of the second configuration:

import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.padding
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material.icons.filled.Home
import androidx.compose.material.icons.filled.Star
import androidx.compose.material.icons.outlined.FavoriteBorder
import androidx.compose.material.icons.outlined.Home
import androidx.compose.material.icons.outlined.StarBorder
import androidx.compose.material3.Icon
import androidx.compose.material3.NavigationBar
import androidx.compose.material3.NavigationBarItem
import androidx.compose.material3.NavigationItemIconPosition
import androidx.compose.material3.ShortNavigationBar
import androidx.compose.material3.ShortNavigationBarArrangement
import androidx.compose.material3.ShortNavigationBarItem
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableIntStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

var selectedItem by remember { mutableIntStateOf(0) }
val items = listOf("Songs", "Artists", "Playlists")
val selectedIcons = listOf(Icons.Filled.Home, Icons.Filled.Favorite, Icons.Filled.Star)
val unselectedIcons =
    listOf(Icons.Outlined.Home, Icons.Outlined.FavoriteBorder, Icons.Outlined.StarBorder)

Column {
    Text(
        "Note: this is configuration is better displayed in medium screen sizes.",
        Modifier.padding(16.dp)
    )

    Spacer(Modifier.height(32.dp))

    ShortNavigationBar(arrangement = ShortNavigationBarArrangement.Centered) {
        items.forEachIndexed { index, item ->
            ShortNavigationBarItem(
                iconPosition = NavigationItemIconPosition.Start,
                icon = {
                    Icon(
                        if (selectedItem == index) selectedIcons[index]
                        else unselectedIcons[index],
                        contentDescription = null
                    )
                },
                label = { Text(item) },
                selected = selectedItem == index,
                onClick = { selectedItem = index }
            )
        }
    }
}

See ShortNavigationBarItem for configurations specific to each item, and not the overall ShortNavigationBar component.

Parameters
modifier: Modifier = Modifier

the Modifier to be applied to this navigation bar
containerColor: Color = ShortNavigationBarDefaults.containerColor

the color used for the background of this navigation bar. Use Color.Transparent to have no color
contentColor: Color = ShortNavigationBarDefaults.contentColor

the color for content inside this navigation bar.
windowInsets: WindowInsets = ShortNavigationBarDefaults.windowInsets

a window insets of the navigation bar
arrangement: ShortNavigationBarArrangement = ShortNavigationBarDefaults.arrangement

the ShortNavigationBarArrangement of this navigation bar
content: @Composable () -> Unit

the content of this navigation bar, typically ShortNavigationBarItems

ShortNavigationBarItem

Cmn 
@ExperimentalMaterial3ExpressiveApi
@Composable
fun ShortNavigationBarItem(
    selected: Boolean,
    onClick: () -> Unit,
    icon: @Composable () -> Unit,
    label: (@Composable () -> Unit)?,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    iconPosition: NavigationItemIconPosition = NavigationItemIconPosition.Top,
    colors: NavigationItemColors = ShortNavigationBarItemDefaults.colors(),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design short navigation bar item.

Short navigation bars offer a persistent and convenient way to switch between primary destinations in an app.

It's recommend for navigation items to always have a text label. An ShortNavigationBarItem always displays labels (if they exist) when selected and unselected.

The ShortNavigationBarItem supports two different icon positions, top and start, which is controlled by the iconPosition param:

  • If the icon position is NavigationItemIconPosition.Top the icon will be displayed above the label. This configuration is recommended for short navigation bars used in small width screens, like a phone in portrait mode.

  • If the icon position is NavigationItemIconPosition.Start the icon will be displayed to the start of the label. This configuration is recommended for short navigation bars used in medium width screens, like a phone in landscape mode.

Parameters
selected: Boolean

whether this item is selected
onClick: () -> Unit

called when this item is clicked
icon: @Composable () -> Unit

icon for this item, typically an Icon
label: (@Composable () -> Unit)?

text label for this item
modifier: Modifier = Modifier

}
Parameters
value: Float

current value of the slider. If outside of valueRange provided, value will be coerced to this range.
onValueChange: (Float) -> Unit

callback in which value should be updated
modifier: Modifier = Modifier

the Modifier to be applied to this slider
enabled: Boolean = true

controls the enabled state of this slider. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
valueRange: ClosedFloatingPointRange<Float> = 0f..1f

range of values that this slider can take. The passed value will be coerced to this range.
steps: @IntRange(from = 0) Int = 0

if positive, specifies the amount of discrete allowable values (in addition to the endpoints of the value range). Step values are evenly distributed across the range. If 0, the slider will behave continuously and allow any value from the range. Must not be negative.
onValueChangeFinished: (() -> Unit)? = null

called when value change has ended. This should not be used to update the slider value (use onValueChange instead), but rather to know when the user has completed selecting a new value by ending a drag or a click.
colors: SliderColors = SliderDefaults.colors()

SliderColors that will be used to resolve the colors used for this slider in different states. See SliderDefaults.colors.
interactionSource: MutableInteractionSource = remember { MutableInteractionSource() }

the MutableInteractionSource representing the stream of Interactions for this slider. You can create and pass in your own remembered instance to observe Interactions and customize the appearance / behavior of this slider in different states.

Use continuous sliders to allow users to make meaningful selections that don’t require a specific value:

import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.padding
import androidx.compose.material3.Slider
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.semantics.contentDescription
import androidx.compose.ui.semantics.semantics
import androidx.compose.ui.unit.dp

var sliderPosition by remember { mutableStateOf(0f) }
Column(modifier = Modifier.padding(horizontal = 16.dp)) {
    Text(text = "%.2f".format(sliderPosition))
    Slider(
        modifier = Modifier.semantics { contentDescription = "Localized Description" },
        value = sliderPosition,
        onValueChange = { sliderPosition = it }
    )
}

You can allow the user to choose only between predefined set of values by specifying the amount of steps between min and max values:

import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.padding
import androidx.compose.material3.Slider
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.semantics.contentDescription
import androidx.compose.ui.semantics.semantics
import androidx.compose.ui.unit.dp

var sliderPosition by remember { mutableStateOf(0f) }
Column(modifier = Modifier.padding(horizontal = 16.dp)) {
    Text(text = sliderPosition.roundToInt().toString())
    Slider(
        modifier = Modifier.semantics { contentDescription = "Localized Description" },
        value = sliderPosition,
        onValueChange = { sliderPosition = it },
        valueRange = 0f..100f,
        onValueChangeFinished = {
            // launch some business logic update with the state you hold
            // viewModel.updateSelectedSliderValue(sliderPosition)
        },
        // Only allow multiples of 10. Excluding the endpoints of `valueRange`,
        // there are 9 steps (10, 20, ..., 90).
        steps = 9
    )
}

Slider using a custom thumb:

var sliderPosition by remember { mutableStateOf(0f) }
val interactionSource: MutableInteractionSource = remember { MutableInteractionSource() }
Column(modifier = Modifier.padding(horizontal = 16.dp)) {
    Slider(
        modifier = Modifier.semantics { contentDescription = "Localized Description" },
        value = sliderPosition,
        onValueChange = { sliderPosition = it },
        valueRange = 0f..100f,
        interactionSource = interactionSource,
        onValueChangeFinished = {
            // launch some business logic update with the state you hold
            // viewModel.updateSelectedSliderValue(sliderPosition)
        },
        thumb = {
            Label(
                label = {
                    PlainTooltip(modifier = Modifier.sizeIn(45.dp, 25.dp).wrapContentWidth()) {
                        Text("%.2f".format(sliderPosition))
                    }
                },
                interactionSource = interactionSource
            ) {
                Icon(
                    imageVector = Icons.Filled.Favorite,
                    contentDescription = null,
                    modifier = Modifier.size(ButtonDefaults.IconSize),
                    tint = Color.Red
                )
            }
        }
    )
}

        },
        track = { SliderDefaults.Track(colors = colors, sliderState = sliderState) }
    )
}
Parameters
value: Float

current value of the slider. If outside of valueRange provided, value will be coerced to this range.
onValueChange: (Float) -> Unit

callback in which value should be updated
modifier: Modifier = Modifier

the Modifier to be applied to this slider
enabled: Boolean = true

controls the enabled state of this slider. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
onValueChangeFinished: (() -> Unit)? = null

called when value change has ended. This should not be used to update the slider value (use onValueChange instead), but rather to know when the user has completed selecting a new value by ending a drag or a click.
colors: SliderColors = SliderDefaults.colors()

SliderColors that will be used to resolve the colors used for this slider in different states. See SliderDefaults.colors.
interactionSource: MutableInteractionSource = remember { MutableInteractionSource() }

the MutableInteractionSource representing the stream of Interactions for this slider. You can create and pass in your own remembered instance to observe Interactions and customize the appearance / behavior of this slider in different states.
steps: @IntRange(from = 0) Int = 0

if positive, specifies the amount of discrete allowable values (in addition to the endpoints of the value range). Step values are evenly distributed across the range. If 0, the slider will behave continuously and allow any value from the range. Must not be negative.
thumb: @Composable (SliderState) -> Unit = { SliderDefaults.Thumb( interactionSource = interactionSource, colors = colors, enabled = enabled ) }

the thumb to be displayed on the slider, it is placed on top of the track. The lambda receives a SliderState which is used to obtain the current active track.
track: @Composable (SliderState) -> Unit = { sliderState -> SliderDefaults.Track(colors = colors, enabled = enabled, sliderState = sliderState) }

the track to be displayed on the slider, it is placed underneath the thumb. The lambda receives a SliderState which is used to obtain the current active track.
valueRange: ClosedFloatingPointRange<Float> = 0f..1f

range of values that this slider can take. The passed value will be coerced to this range.

SmallExtendedFloatingActionButton

@ExperimentalMaterial3ExpressiveApi
@Composable
fun SmallExtendedFloatingActionButton(
    onClick: () -> Unit,
    modifier: Modifier = Modifier,
    shape: Shape = FloatingActionButtonDefaults.smallExtendedFabShape,
    containerColor: Color = FloatingActionButtonDefaults.containerColor,
    contentColor: Color = contentColorFor(containerColor),
    elevation: FloatingActionButtonElevation = FloatingActionButtonDefaults.elevation(),
    interactionSource: MutableInteractionSource? = null,
    content: @Composable RowScope.() -> Unit
): Unit

Material Design small extended floating action button.

Extended FABs help people take primary actions. They're wider than FABs to accommodate a text label and larger target area.

The other small extended floating action button overload supports a text label and icon.

import androidx.compose.material3.ExtendedFloatingActionButton
import androidx.compose.material3.FloatingActionButton
import androidx.compose.material3.SmallExtendedFloatingActionButton
import androidx.compose.material3.Text

SmallExtendedFloatingActionButton(onClick = { /* do something */ }) {
    Text(text = "Small Extended FAB")
}
Parameters
onClick: () -> Unit

called when this FAB is clicked
modifier: Modifier = Modifier

the Modifier to be applied to this FAB
shape: Shape = FloatingActionButtonDefaults.smallExtendedFabShape

defines the shape of this FAB's container and shadow (when using elevation)
containerColor: Color = FloatingActionButtonDefaults.containerColor

the color used for the background of this FAB. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(containerColor)

the preferred color for content inside this FAB. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
elevation: FloatingActionButtonElevation = FloatingActionButtonDefaults.elevation()

FloatingActionButtonElevation used to resolve the elevation for this FAB in different states. This controls the size of the shadow below the FAB. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. See also: Surface.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this FAB. You can use this to change the FAB's appearance or preview the FAB in different states. Note that if null is provided, interactions will still happen internally.
content: @Composable RowScope.() -> Unit

the content of this FAB, typically a Text label

): Unit

Material Design snackbar.

Snackbars provide brief messages about app processes at the bottom of the screen.

![Snackbar

  • image](https://developer.android.com/images/reference/androidx/compose/material3/snackbar.png)

Snackbars inform users of a process that an app has performed or will perform. They appear temporarily, towards the bottom of the screen. They shouldn’t interrupt the user experience, and they don’t require user input to disappear.

A Snackbar can contain a single action. "Dismiss" or "cancel" actions are optional.

Snackbars with an action should not timeout or self-dismiss until the user performs another action. Here, moving the keyboard focus indicator to navigate through interactive elements in a page is not considered an action.

This version of snackbar is designed to work with SnackbarData provided by the SnackbarHost, which is usually used inside of the Scaffold.

This components provides only the visuals of the Snackbar. If you need to show a Snackbar with defaults on the screen, use SnackbarHostState.showSnackbar:

import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.layout.wrapContentSize
import androidx.compose.material3.ExtendedFloatingActionButton
import androidx.compose.material3.Scaffold
import androidx.compose.material3.Snackbar
import androidx.compose.material3.SnackbarHost
import androidx.compose.material3.SnackbarHostState
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.runtime.rememberCoroutineScope
import androidx.compose.ui.Modifier

val snackbarHostState = remember { SnackbarHostState() }
val scope = rememberCoroutineScope()
Scaffold(
    snackbarHost = { SnackbarHost(snackbarHostState) },
    floatingActionButton = {
        var clickCount by remember { mutableStateOf(0) }
        ExtendedFloatingActionButton(
            onClick = {
                // show snackbar as a suspend function
                scope.launch { snackbarHostState.showSnackbar("Snackbar # ${++clickCount}") }
            }
        ) {
            Text("Show snackbar")
        }
    },
    content = { innerPadding ->
        Text(
            text = "Body content",
            modifier = Modifier.padding(innerPadding).fillMaxSize().wrapContentSize()
        )
    }
)

If you want to customize appearance of the Snackbar, you can pass your own version as a child of the SnackbarHost to the Scaffold:

Material Design snackbar.

Snackbars provide brief messages about app processes at the bottom of the screen.

![Snackbar

  • image](https://developer.android.com/images/reference/androidx/compose/material3/snackbar.png)

Snackbars inform users of a process that an app has performed or will perform. They appear temporarily, towards the bottom of the screen. They shouldn’t interrupt the user experience, and they don’t require user input to disappear.

A Snackbar can contain a single action. "Dismiss" or "cancel" actions are optional.

Snackbars with an action should not timeout or self-dismiss until the user performs another action. Here, moving the keyboard focus indicator to navigate through interactive elements in a page is not considered an action.

This component provides only the visuals of the Snackbar. If you need to show a Snackbar with defaults on the screen, use SnackbarHostState.showSnackbar:

import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.layout.wrapContentSize
import androidx.compose.material3.ExtendedFloatingActionButton
import androidx.compose.material3.Scaffold
import androidx.compose.material3.Snackbar
import androidx.compose.material3.SnackbarHost
import androidx.compose.material3.SnackbarHostState
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.runtime.rememberCoroutineScope
import androidx.compose.ui.Modifier

val snackbarHostState = remember { SnackbarHostState() }
val scope = rememberCoroutineScope()
Scaffold(
    snackbarHost = { SnackbarHost(snackbarHostState) },
    floatingActionButton = {
        var clickCount by remember { mutableStateOf(0) }
        ExtendedFloatingActionButton(
            onClick = {
                // show snackbar as a suspend function
                scope.launch { snackbarHostState.showSnackbar("Snackbar # ${++clickCount}") }
            }
        ) {
            Text("Show snackbar")
        }
    },
    content = { innerPadding ->
        Text(
            text = "Body content",
            modifier = Modifier.padding(innerPadding).fillMaxSize().wrapContentSize()
        )
    }
)

If you want to customize appearance of the Snackbar, you can pass your own version as a child of the SnackbarHost to the Scaffold:

Choose the best split button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

Use SplitButtonDefaults.LeadingButton and SplitButtonDefaults.TrailingButton to construct a FilledSplitButton. Filled split button is the high-emphasis version of split button. It should be used for emphasizing important or final actions.

Use SplitButtonDefaults.TonalLeadingButton and SplitButtonDefaults.TonalTrailingButton to construct a tonal SplitButton. Tonal split button is the medium-emphasis version of split buttons. It's a middle ground between filled SplitButton and outlined SplitButton

Use SplitButtonDefaults.ElevatedLeadingButton and SplitButtonDefaults.ElevatedTrailingButton to construct a elevated SplitButton. Elevated split buttons are essentially tonal SplitButtons with a shadow. To prevent shadow creep, only use them when absolutely necessary, such as when the button requires visual separation from patterned container.

Use SplitButtonDefaults.OutlinedLeadingButton and SplitButtonDefaults.OutlinedTrailingButton to construct a outlined SplitButton. Outlined split buttons are medium-emphasis buttons. They contain actions that are important, but are not the primary action in an app. Outlined buttons pair well with filled SplitButtons to indicate an alternative, secondary action.

Parameters
leadingButton: @Composable () -> Unit

the leading button. You can specify your own composable or construct a SplitButtonDefaults.LeadingButton
trailingButton: @Composable () -> Unit

the trailing button.You can specify your own composable or construct a SplitButtonDefaults.TrailingButton
modifier: Modifier = Modifier

the Modifier to be applied to this split button.
spacing: Dp = SplitButtonDefaults.Spacing

The spacing between the leadingButton and trailingButton

SuggestionChip

Cmn 
@Composable
fun SuggestionChip(
    onClick: () -> Unit,
    label: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    icon: (@Composable () -> Unit)? = null,
    shape: Shape = SuggestionChipDefaults.shape,
    colors: ChipColors = SuggestionChipDefaults.suggestionChipColors(),
    elevation: ChipElevation? = SuggestionChipDefaults.suggestionChipElevation(),
    border: BorderStroke? = SuggestionChipDefaults.suggestionChipBorder(enabled),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design suggestion chip.

Chips help people enter information, make selections, filter content, or trigger actions. Chips can show multiple interactive elements together in the same area, such as a list of selectable movie times, or a series of email contacts.

Suggestion chips help narrow a user's intent by presenting dynamically generated suggestions, such as possible responses or search filters.

![Suggestion chip

  • image](https://developer.android.com/images/reference/androidx/compose/material3/suggestion-chip.png)

This suggestion chip is applied with a flat style. If you want an elevated style, use the ElevatedSuggestionChip.

Example of a flat SuggestionChip with a trailing icon:

import androidx.compose.material3.SuggestionChip
import androidx.compose.material3.Text

SuggestionChip(onClick = { /* Do something! */ }, label = { Text("Suggestion Chip") })
Parameters
onClick: () -> Unit

called when this chip is clicked
label: @Composable () -> Unit

text label for this chip
modifier: Modifier = Modifier

the Modifier to be applied to this chip
enabled: Boolean = true

controls the enabled state of this chip. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
icon: (@Composable () -> Unit)? = null

optional icon at the start of the chip, preceding the label text
shape: Shape = SuggestionChipDefaults.shape

defines the shape of this chip's container, border (when border is not null), and shadow (when using elevation)
colors: ChipColors = SuggestionChipDefaults.suggestionChipColors()

ChipColors that will be used to resolve the colors used for this chip in different states. See SuggestionChipDefaults.suggestionChipColors.
elevation: ChipElevation? = SuggestionChipDefaults.suggestionChipElevation()

ChipElevation used to resolve the elevation for this chip in different states. This controls the size of the shadow below the chip. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. See SuggestionChipDefaults.suggestionChipElevation.
border: BorderStroke? = SuggestionChipDefaults.suggestionChipBorder(enabled)

the border to draw around the container of this chip. Pass null for no border. See SuggestionChipDefaults.suggestionChipBorder.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this chip. You can use this to change the chip's appearance or preview the chip in different states. Note that if null is provided, interactions will still happen internally.

Surface

Cmn 
@Composable
@NonRestartableComposable
fun Surface(
    modifier: Modifier = Modifier,
    shape: Shape = RectangleShape,
    color: Color = MaterialTheme.colorScheme.surface,
    contentColor: Color = contentColorFor(color),
    tonalElevation: Dp = 0.dp,
    shadowElevation: Dp = 0.dp,
    border: BorderStroke? = null,
    content: @Composable () -> Unit
): Unit

Material surface is the central metaphor in material design. Each surface exists at a given elevation, which influences how that piece of surface visually relates to other surfaces and how that surface is modified by tonal variance.

See the other overloads for clickable, selectable, and toggleable surfaces.

The Surface is responsible for:

  1. Clipping: Surface clips its children to the shape specified by shape

  2. Borders: If shape has a border, then it will also be drawn.

  3. Background: Surface fills the shape specified by shape with the color. If color is ColorScheme.surface a color overlay will be applied. The color of the overlay depends on the tonalElevation of this Surface, and the LocalAbsoluteTonalElevation set by any parent surfaces. This ensures that a Surface never appears to have a lower elevation overlay than its ancestors, by summing the elevation of all previous Surfaces.

  4. Content color: Surface uses contentColor to specify a preferred color for the content of this surface - this is used by the Text and Icon components as a default color.

If no contentColor is set, this surface will try and match its background color to a color defined in the theme ColorScheme, and return the corresponding content color. For example, if the color of this surface is ColorScheme.surface, contentColor will be set to ColorScheme.onSurface. If color is not part of the theme palette, contentColor will keep the same value set above this Surface.

To manually retrieve the content color inside a surface, use LocalContentColor.

  1. Blocking touch propagation behind the surface.

Surface sample:

import androidx.compose.material3.Surface
import androidx.compose.material3.Text

Surface { Text("Text on Surface") }
Parameters
modifier: Modifier = Modifier

Modifier to be applied to the layout corresponding to the surface
shape: Shape = RectangleShape

Defines the surface's shape as well its shadow.
color: Color = MaterialTheme.colorScheme.surface

The background color. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(color)

The preferred content color provided by this Surface to its children. Defaults to either the matching content color for color, or if color is not a color from the theme, this will keep the same value set above this Surface.
tonalElevation: Dp = 0.dp

When color is ColorScheme.surface, a higher the elevation will result in a darker color in light theme and lighter color in dark theme.
shadowElevation: Dp = 0.dp

The size of the shadow below the surface. To prevent shadow creep, only apply shadow elevation when absolutely necessary, such as when the surface requires visual separation from a patterned background. Note that It will not affect z index of the Surface. If you want to change the drawing order you can use Modifier.zIndex.
border: BorderStroke? = null

Optional border to draw on top of the surface
content: @Composable () -> Unit

The content to be displayed on this Surface

Surface

Cmn 
@Composable
@NonRestartableComposable
fun Surface(
    onClick: () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    shape: Shape = RectangleShape,
    color: Color = MaterialTheme.colorScheme.surface,
    contentColor: Color = contentColorFor(color),
    tonalElevation: Dp = 0.dp,
    shadowElevation: Dp = 0.dp,
    border: BorderStroke? = null,
    interactionSource: MutableInteractionSource? = null,
    content: @Composable () -> Unit
): Unit

Material surface is the central metaphor in material design. Each surface exists at a given elevation, which influences how that piece of surface visually relates to other surfaces and how that surface is modified by tonal variance.

This version of Surface is responsible for a click handling as well as everything else that a regular Surface does:

This clickable Surface is responsible for:

  1. Clipping: Surface clips its children to the shape specified by shape

  2. Borders: If shape has a border, then it will also be drawn.

  3. Background: Surface fills the shape specified by shape with the color. If color is ColorScheme.surface a color overlay may be applied. The color of the overlay depends on the tonalElevation of this Surface, and the LocalAbsoluteTonalElevation set by any parent surfaces. This ensures that a Surface never appears to have a lower elevation overlay than its ancestors, by summing the elevation of all previous Surfaces.

  4. Content color: Surface uses contentColor to specify a preferred color for the content of this surface - this is used by the Text and Icon components as a default color. If no contentColor is set, this surface will try and match its background color to a color defined in the theme ColorScheme, and return the corresponding content color. For example, if the color of this surface is ColorScheme.surface, contentColor will be set to ColorScheme.onSurface. If color is not part of the theme palette, contentColor will keep the same value set above this Surface.

  5. Click handling. This version of surface will react to the clicks, calling onClick lambda, updating the interactionSource when PressInteraction occurs, and showing ripple indication in response to press events. If you don't need click handling, consider using the Surface function that doesn't require onClick param. If you need to set a custom label for the onClick, apply a Modifier.semantics { onClick(label = "YOUR_LABEL", action = null) } to the Surface.

  6. Semantics for clicks. Just like with Modifier.clickable, clickable version of Surface will produce semantics to indicate that it is clicked. No semantic role is set by default, you may specify one by passing a desired Role with a Modifier.semantics.

To manually retrieve the content color inside a surface, use LocalContentColor.

Clickable surface sample:

import androidx.compose.material3.Surface
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember

var count by remember { mutableStateOf(0) }
Surface(
    onClick = { count++ },
) {
    Text("Clickable Surface. Count: $count")
}
Parameters
onClick: () -> Unit

callback to be called when the surface is clicked
modifier: Modifier = Modifier

Modifier to be applied to the layout corresponding to the surface
enabled: Boolean = true

Controls the enabled state of the surface. When false, this surface will not be clickable
shape: Shape = RectangleShape

Defines the surface's shape as well its shadow. A shadow is only displayed if the tonalElevation is greater than zero.
color: Color = MaterialTheme.colorScheme.surface

The background color. Use Color.Transparent to have no color.
contentColor: Color = contentColorFor(color)

The preferred content color provided by this Surface to its children. Defaults to either the matching content color for color, or if color is not a color from the theme, this will keep the same value set above this Surface.
tonalElevation: Dp = 0.dp

When color is ColorScheme.surface, a higher the elevation will result in a darker color in light theme and lighter color in dark theme.
shadowElevation: Dp = 0.dp

The size of the shadow below the surface. Note that It will not affect z index of the Surface. If you want to change the drawing order you can use Modifier.zIndex.
border: BorderStroke? = null

Optional border to draw on top of the surface
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this surface. You can use this to change the surface's appearance or preview the surface in different states. Note that if null is provided, interactions will still happen internally.

Material surface is the central metaphor in material design. Each surface exists at a given elevation, which influences how that piece of surface visually relates to other surfaces and how that surface is modified by tonal variance.

This version of Surface is responsible for a toggling its checked state as well as everything else that a regular Surface does:

This toggleable Surface is responsible for:

  1. Clipping: Surface clips its children to the shape specified by shape

  2. Borders: If shape has a border, then it will also be drawn.

  3. Background: Surface fills the shape specified by shape with the color. If color is ColorScheme.surface a color overlay may be applied. The color of the overlay depends on the tonalElevation of this Surface, and the LocalAbsoluteTonalElevation set by any parent surfaces. This ensures that a Surface never appears to have a lower elevation overlay than its ancestors, by summing the elevation of all previous Surfaces.

  4. Content color: Surface uses contentColor to specify a preferred color for the content of this surface - this is used by the Text and Icon components as a default color. If no contentColor is set, this surface will try and match its background color to a color defined in the theme ColorScheme, and return the corresponding content color. For example, if the color of this surface is ColorScheme.surface, contentColor will be set to ColorScheme.onSurface. If color is not part of the theme palette, contentColor will keep the same value set above this Surface.

  5. Click handling. This version of surface will react to the check toggles, calling onCheckedChange lambda, updating the interactionSource when PressInteraction occurs, and showing ripple indication in response to press events. If you don't need check handling, consider using a Surface function that doesn't require onCheckedChange param.

  6. Semantics for toggle. Just like with Modifier.toggleable, toggleable version of Surface will produce semantics to indicate that it is checked. No semantic role is set by default, you may specify one by passing a desired Role with a Modifier.semantics.

To manually retrieve the content color inside a surface, use LocalContentColor.

Material surface is the central metaphor in material design. Each surface exists at a given elevation, which influences how that piece of surface visually relates to other surfaces and how that surface is modified by tonal variance.

This version of Surface is responsible for a selection handling as well as everything else that a regular Surface does:

This selectable Surface is responsible for:

  1. Clipping: Surface clips its children to the shape specified by shape

  2. Borders: If shape has a border, then it will also be drawn.

  3. Background: Surface fills the shape specified by shape with the color. If color is ColorScheme.surface a color overlay may be applied. The color of the overlay depends on the tonalElevation of this Surface, and the LocalAbsoluteTonalElevation set by any parent surfaces.

        },
    divider: @Composable () -> Unit = @Composable { HorizontalDivider() },
    tabs: @Composable () -> Unit
): Unit

Material Design tabs

Material Design fixed tabs.

For primary indicator tabs, use PrimaryTabRow. For secondary indicator tabs, use SecondaryTabRow.

Fixed tabs display all tabs in a set simultaneously. They are best for switching between related content quickly, such as between transportation methods in a map. To navigate between fixed tabs, tap an individual tab, or swipe left or right in the content area.

A TabRow contains a row of Tabs, and displays an indicator underneath the currently selected tab. A TabRow places its tabs evenly spaced along the entire row, with each tab taking up an equal amount of space. See ScrollableTabRow for a tab row that does not enforce equal size, and allows scrolling to tabs that do not fit on screen.

A simple example with text tabs looks like:

import androidx.compose.foundation.layout.Column
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.PrimaryTabRow
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.text.style.TextOverflow

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3 with lots of text")
Column {
    PrimaryTabRow(selectedTabIndex = state) {
        titles.forEachIndexed { index, title ->
            Tab(
                selected = state == index,
                onClick = { state = index },
                text = { Text(text = title, maxLines = 2, overflow = TextOverflow.Ellipsis) }
            )
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Text tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}

You can also provide your own custom tab, such as:

import androidx.compose.foundation.layout.Column
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.SecondaryTabRow
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3")
Column {
    SecondaryTabRow(selectedTabIndex = state) {
        titles.forEachIndexed { index, title ->
            FancyTab(title = title, onClick = { state = index }, selected = (index == state))
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Fancy tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}

Where the custom tab itself could look like:

import androidx.compose.foundation.background
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.layout.size
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

Tab(selected, onClick) {
    Column(
        Modifier.padding(10.dp).height(50.dp).fillMaxWidth(),
        verticalArrangement = Arrangement.SpaceBetween
    ) {
        Box(
            Modifier.size(10.dp)
                .align(Alignment.CenterHorizontally)
                .background(
                    color =
                        if (selected) MaterialTheme.colorScheme.primary
                        else MaterialTheme.colorScheme.background
                )
        )
        Text(
            text = title,
            style = MaterialTheme.typography.bodyLarge,
            modifier = Modifier.align(Alignment.CenterHorizontally)
        )
    }
}

As well as customizing the tab, you can also provide a custom indicator, to customize the indicator displayed for a tab. indicator will be placed to fill the entire TabRow, so it should internally take care of sizing and positioning the indicator to match changes to selectedTabIndex.

For example, given an indicator that draws a rounded rectangle near the edges of the Tab:

import androidx.compose.foundation.BorderStroke
import androidx.compose.foundation.border
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.shape.RoundedCornerShape
import androidx.compose.material3.Tab
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.graphics.drawscope.Stroke
import androidx.compose.ui.unit.dp

// Draws a rounded rectangular with border around the Tab, with a 5.dp padding from the edges
// Color is passed in as a parameter [color]

We can reuse TabRowDefaults.tabIndicatorOffset and just provide this indicator, as we aren't changing how the size and position of the indicator changes between tabs:

import androidx.compose.foundation.layout.Column
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.SecondaryTabRow
import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3")

Column {
    SecondaryTabRow(
        selectedTabIndex = state,
        indicator = {
            FancyIndicator(
                MaterialTheme.colorScheme.primary,
                Modifier.tabIndicatorOffset(state)
            )
        }
    ) {
        titles.forEachIndexed { index, title ->
            Tab(selected = state == index, onClick = { state = index }, text = { Text(title) })
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Fancy indicator tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}

You may also want to use a custom transition, to allow you to dynamically change the appearance of the indicator as it animates between tabs, such as changing its color or size. indicator is stacked on top of the entire TabRow, so you just need to provide a custom transition that animates the offset of the indicator from the start of the TabRow. For example, take the following example that uses a transition to animate the offset, width, and color of the same FancyIndicator from before, also adding a physics based 'spring' effect to the indicator in the direction of motion:

We can now just pass this indicator directly to TabRow:

import androidx.compose.material3.Tab
import androidx.compose.material3.Text
import androidx.compose.runtime.mutableStateOf

import androidx.compose.ui.Modifier

var state by remember { mutableStateOf(0) }
val titles = listOf("Tab 1", "Tab 2", "Tab 3")

Column {
    SecondaryTabRow(
        selectedTabIndex = state,
        indicator = { FancyAnimatedIndicatorWithModifier(state) }
    ) {
        titles.forEachIndexed { index, title ->
            Tab(selected = state == index, onClick = { state = index }, text = { Text(title) })
        }
    }
    Text(
        modifier = Modifier.align(Alignment.CenterHorizontally),
        text = "Fancy transition tab ${state + 1} selected",
        style = MaterialTheme.typography.bodyLarge
    )
}
Parameters
selectedTabIndex: Int

the index of the currently selected tab
modifier: Modifier = Modifier

the Modifier to be applied to this tab row
containerColor: Color = TabRowDefaults.primaryContainerColor

the color used for the background of this tab row. Use Color.Transparent to have no color.
contentColor: Color = TabRowDefaults.primaryContentColor

the preferred color for content inside this tab row. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
indicator: @Composable (tabPositions: List<TabPosition>) -> Unit = @Composable { tabPositions -> if (selectedTabIndex < tabPositions.size) { TabRowDefaults.SecondaryIndicator( Modifier.tabIndicatorOffset(tabPositions[selectedTabIndex]) ) } }

the indicator that represents which tab is currently selected. By default this will be a TabRowDefaults.SecondaryIndicator, using a TabRowDefaults.tabIndicatorOffset modifier to animate its position. Note that this indicator will be forced to fill up the entire tab row, so you should use TabRowDefaults.tabIndicatorOffset or similar to animate the actual drawn indicator inside this space, and provide an offset from the start.
divider: @Composable () -> Unit = @Composable { HorizontalDivider() }

the divider displayed at the bottom of the tab row. This provides a layer of separation between the tab row and the content displayed underneath.
tabs: @Composable () -> Unit

the tabs inside this tab row. Typically this will be multiple Tabs. Each element inside this lambda will be measured and placed evenly across the row, each taking up equal space.

@Composable
fun Text(
    text: String,
    modifier: Modifier = Modifier,
    color: Color = Color.Unspecified,
    fontSize: TextUnit = TextUnit.Unspecified,

    onTextLayout: ((TextLayoutResult) -> Unit)? = null,
    style: TextStyle = LocalTextStyle.current
): Unit

High level element that displays text and provides semantics / accessibility information.

The default style uses the LocalTextStyle provided by the MaterialTheme / components. If you are setting your own style, you may want to consider first retrieving LocalTextStyle, and using TextStyle.copy to keep any theme defined attributes, only modifying the specific attributes you want to override.

For ease of use, commonly used parameters from TextStyle are also present here. The order of precedence is as follows:

  • If a parameter is explicitly set here (i.e, it is not null or TextUnit.Unspecified), then this parameter will always be used.

  • If a parameter is not set, (null or TextUnit.Unspecified), then the corresponding value from style will be used instead.

Additionally, for color, if color is not set, and style does not have a color, then LocalContentColor will be used.

Parameters
text: String

the text to be displayed
modifier: Modifier = Modifier

the Modifier to be applied to this layout node
color: Color = Color.Unspecified

Color to apply to the text. If Color.Unspecified, and style has no color set, this will be LocalContentColor.
fontSize: TextUnit = TextUnit.Unspecified

the size of glyphs to use when painting the text. See TextStyle.fontSize.
fontStyle: FontStyle? = null

the typeface variant to use when drawing the letters (e.g., italic). See TextStyle.fontStyle.
fontWeight: FontWeight? = null

the typeface thickness to use when painting the text (e.g., FontWeight.Bold).

lineHeight: TextUnit = TextUnit.Unspecified

line height for the Paragraph in TextUnit unit, e.g. SP or EM. See TextStyle.lineHeight.
overflow: TextOverflow = TextOverflow.Clip

how visual overflow should be handled.
softWrap: Boolean = true

): Unit

Material Design text button.

Buttons help people initiate actions, from sending an email, to sharing a document, to liking a post.

![Text button

  • image](https://developer.android.com/images/reference/androidx/compose/material3/text-button.png)

Text buttons are typically used for less-pronounced actions, including those located in dialogs and cards. In cards, text buttons help maintain an emphasis on card content. Text buttons are used for the lowest priority actions, especially when presenting multiple options.

import androidx.compose.material3.Button
import androidx.compose.material3.Text
import androidx.compose.material3.TextButton

TextButton(onClick = { /* Do something! */ }) { Text("Text Button") }

Choose the best button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

The default text style for internal Text components will be set to Typography.labelLarge.

Parameters
onClick: () -> Unit

called when this button is clicked
modifier: Modifier = Modifier

the Modifier to be applied to this button
enabled: Boolean = true

controls the enabled state of this button. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
shape: Shape = ButtonDefaults.textShape

defines the shape of this button's container, border (when border is not null), and shadow (when using elevation)
colors: ButtonColors = ButtonDefaults.textButtonColors()

ButtonColors that will be used to resolve the colors for this button in different states. See ButtonDefaults.textButtonColors.
elevation: ButtonElevation? = null

ButtonElevation used to resolve the elevation for this button in different states. This controls the size of the shadow below the button. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. A TextButton typically has no elevation, and the default value is null. See ElevatedButton for a button with elevation.
border: BorderStroke? = null

the border to draw around the container of this button
contentPadding: PaddingValues = ButtonDefaults.TextButtonContentPadding

the spacing values to apply internally between the container and the content
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this button. You can use this to change the button's appearance or preview the button in different states. Note that if null is provided, interactions will still happen internally.
content: @Composable RowScope.() -> Unit

The content displayed on the button, expected to be text.

): Unit

Material Design filled text field.

Text fields allow users to enter text into a UI. They typically appear in forms and dialogs. Filled text fields have more visual emphasis than outlined text fields, making them stand out when surrounded by other content and components.

![Filled text field

  • image](https://developer.android.com/images/reference/androidx/compose/material3/filled-text-field.png)

If you are looking for an outlined version, see OutlinedTextField.

If apart from input text change you also want to observe the cursor location, selection range, or IME composition use the TextField overload with the TextFieldValue parameter instead.

Parameters
value: String

the input text to be shown in the text field
onValueChange: (String) -> Unit

the callback that is triggered when the input service updates the text. An updated text comes as a parameter of the callback
modifier: Modifier = Modifier

the Modifier to be applied to this text field
enabled: Boolean = true

controls the enabled state of this text field. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
readOnly: Boolean = false

controls the editable state of the text field. When true, the text field cannot be modified. However, a user can focus it and copy text from it. Read-only text fields are usually used to display pre-filled forms that a user cannot edit.
textStyle: TextStyle = LocalTextStyle.current

the style to be applied to the input text. Defaults to LocalTextStyle.
label: (@Composable () -> Unit)? = null

the optional label to be displayed with this text field. The default text style uses Typography.bodySmall when minimized and Typography.bodyLarge when expanded.
placeholder: (@Composable () -> Unit)? = null

the optional placeholder to be displayed when the text field is in focus and the input text is empty. The default text style for internal Text is Typography.bodyLarge
leadingIcon: (@Composable () -> Unit)? = null

the optional leading icon to be displayed at the beginning of the text field container
trailingIcon: (@Composable () -> Unit)? = null

the optional trailing icon to be displayed at the end of the text field container
prefix: (@Composable () -> Unit)? = null

the optional prefix to be displayed before the input text in the text field
suffix: (@Composable () -> Unit)? = null

the optional suffix to be displayed after the input text in the text field
supportingText: (@Composable () -> Unit)? = null

the optional supporting text to be displayed below the text field
isError: Boolean = false

indicates if the text field's current value is in error. If set to true, the label, bottom indicator and trailing icon by default will be displayed in error color
visualTransformation: VisualTransformation = VisualTransformation.None

transforms the visual representation of the input value For example, you can use PasswordVisualTransformation to create a password text field. By default, no visual transformation is applied.
keyboardOptions: KeyboardOptions = KeyboardOptions.Default

software keyboard options that contains configuration such as KeyboardType and ImeAction.
keyboardActions: KeyboardActions = KeyboardActions.Default

when the input service emits an IME action, the corresponding callback is called. Note that this IME action may be different from what you specified in KeyboardOptions.imeAction.
singleLine: Boolean = false

when true, this text field becomes a single horizontally scrolling text field instead of wrapping onto multiple lines. The keyboard will be informed to not show the return key as the ImeAction. Note that maxLines parameter will be ignored as the maxLines attribute will be automatically set to 1.
maxLines: Int = if (singleLine) 1 else Int.MAX_VALUE

the maximum height in terms of maximum number of visible lines. It is required that 1 <= minLines<= maxLines. This parameter is ignored when singleLine is true.
minLines: Int = 1

the minimum height in terms of minimum number of visible lines. It is required that 1 <= minLines<= maxLines. This parameter is ignored when singleLine is true.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this text field. You can use this to change the text field's appearance or preview the text field in different states. Note that if null is provided, interactions will still happen internally.
shape: Shape = TextFieldDefaults.shape

Material Design filled text field.

Text fields allow users to enter text into a UI. They typically appear in forms and dialogs. Filled text fields have more visual emphasis than outlined text fields, making them stand out when surrounded by other content and components.

![Filled text field

  • image](https://developer.android.com/images/reference/androidx/compose/material3/filled-text-field.png)

If you are looking for an outlined version, see OutlinedTextField.

This overload provides access to the input text, cursor position, selection range and IME composition. If you only want to observe an input text change, use the TextField overload with the String parameter instead.

Parameters
value: TextFieldValue

the input TextFieldValue to be shown in the text field
onValueChange: (TextFieldValue) -> Unit

the callback that is triggered when the input service updates values in TextFieldValue. An updated TextFieldValue comes as a parameter of the callback
modifier: Modifier = Modifier

the Modifier to be applied to this text field
enabled: Boolean = true

controls the enabled state of this text field. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
readOnly: Boolean = false

controls the editable state of the text field. When true, the text field cannot be modified. However, a user can focus it and copy text from it. Read-only text fields are usually used to display pre-filled forms that a user cannot edit.
textStyle: TextStyle = LocalTextStyle.current

the style to be applied to the input text. Defaults to LocalTextStyle.
label: (@Composable () -> Unit)? = null

the optional label to be displayed with this text field. The default text style uses Typography.bodySmall when minimized and Typography.bodyLarge when expanded.
placeholder: (@Composable () -> Unit)? = null

the optional placeholder to be displayed when the text field is in focus and the input text is empty. The default text style for internal Text is Typography.bodyLarge
leadingIcon: (@Composable () -> Unit)? = null

the optional leading icon to be displayed at the beginning of the text field container
trailingIcon: (@Composable () -> Unit)? = null

the optional trailing icon to be displayed at the end of the text field container
prefix: (@Composable () -> Unit)? = null

the optional prefix to be displayed before the input text in the text field
suffix: (@Composable () -> Unit)? = null

the optional suffix to be displayed after the input text in the text field
supportingText: (@Composable () -> Unit)? = null

the optional supporting text to be displayed below the text field
isError: Boolean = false

indicates if the text field's current value is in error state. If set to true, the label, bottom indicator and trailing icon by default will be displayed in error color
visualTransformation: VisualTransformation = VisualTransformation.None

transforms the visual representation of the input value. For example, you can use PasswordVisualTransformation to create a password text field. By default, no visual transformation is applied.
keyboardOptions: KeyboardOptions = KeyboardOptions.Default

software keyboard options that contains configuration such as KeyboardType and ImeAction.
keyboardActions: KeyboardActions = KeyboardActions.Default

when the input service emits an IME action, the corresponding callback is called. Note that this IME action may be different from what you specified in KeyboardOptions.imeAction.
singleLine: Boolean = false

when true, this text field becomes a single horizontally scrolling text field instead of wrapping onto multiple lines. The keyboard will be informed to not show the return key as the ImeAction. Note that maxLines parameter will be ignored as the maxLines attribute will be automatically set to 1.
maxLines: Int = if (singleLine) 1 else Int.MAX_VALUE

the maximum height in terms of maximum number of visible lines. It is required that 1 <= minLines<= maxLines. This parameter is ignored when singleLine is true.
minLines: Int = 1

the minimum height in terms of minimum number of visible lines. It is required that 1 <= minLines<= maxLines. This parameter is ignored when singleLine is true.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this text field. You can use this to change the text field's appearance or preview the text field in different states. Note that if null is provided, interactions will still happen internally.
shape: Shape = TextFieldDefaults.shape

defines the shape of this text field's container
colors: TextFieldColors = TextFieldDefaults.colors()

TextFieldColors that will be used to resolve the colors used for this text field in different states. See TextFieldDefaults.colors.

Material Design filled text field.

Text fields allow users to enter text into a UI. They typically appear in forms and dialogs. Filled text fields have more visual emphasis than outlined text fields, making them stand out when surrounded by other content and components.

![Filled text field

  • image](https://developer.android.com/images/reference/androidx/compose/material3/filled-text-field.png)

If you are looking for an outlined version, see OutlinedTextField. For a text field specifically designed for passwords or other secure content, see SecureTextField.

This overload of TextField uses TextFieldState to keep track of its text content and position of the cursor or selection.

A simple single line text field looks like:

import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember

TextField(
    state = rememberTextFieldState(),
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
)

You can control the initial text input and selection:

import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember
import androidx.compose.ui.text.TextRange

val state = rememberTextFieldState("Initial text", TextRange(0, 12))
TextField(
    state = state,
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
)

Use input and output transformations to control user input and the displayed text:

import androidx.compose.foundation.text.KeyboardOptions
import androidx.compose.foundation.text.input.InputTransformation
import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.insert
import androidx.compose.foundation.text.input.maxLength
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.foundation.text.input.then
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember
import androidx.compose.ui.text.input.KeyboardType
import androidx.core.text.isDigitsOnly

TextField(
    state = rememberTextFieldState(),
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Phone number") },
    keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Number),
    // Input transformation to limit user input to 10 digits
    inputTransformation =
        InputTransformation.maxLength(10).then {
            if (!this.asCharSequence().isDigitsOnly()) {
                revertAllChanges()
            }
        },
    outputTransformation = {
        // Output transformation to format as a phone number: (XXX) XXX-XXXX
        if (length > 0) insert(0, "(")
        if (length > 4) insert(4, ") ")
        if (length > 9) insert(9, "-")
    },
)

You may provide a placeholder:

import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Row
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Checkbox
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.material3.TextFieldLabelPosition
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

var alwaysMinimizeLabel by remember { mutableStateOf(false) }
Column {
    Row {
        Checkbox(checked = alwaysMinimizeLabel, onCheckedChange = { alwaysMinimizeLabel = it })
        Text("Show placeholder even when unfocused")
    }
    Spacer(Modifier.height(16.dp))
    TextField(
        state = rememberTextFieldState(),
        lineLimits = TextFieldLineLimits.SingleLine,
        label = { Text("Email") },
        labelPosition = TextFieldLabelPosition.Attached(alwaysMinimize = alwaysMinimizeLabel),
        placeholder = { Text("example@gmail.com") }
    )
}

You can also provide leading and trailing icons:

import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.clearText
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Clear
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material3.Icon
import androidx.compose.material3.IconButton
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember

val state = rememberTextFieldState()

TextField(
    state = state,
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
    leadingIcon = { Icon(Icons.Filled.Favorite, contentDescription = null) },
    trailingIcon = {
        IconButton(onClick = { state.clearText() }) {
            Icon(Icons.Filled.Clear, contentDescription = "Clear text")
        }
    }
)

You can also provide a prefix or suffix to the text:

import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Row
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Checkbox
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.material3.TextFieldLabelPosition
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

var alwaysMinimizeLabel by remember { mutableStateOf(false) }
Column {
    Row {
        Checkbox(checked = alwaysMinimizeLabel, onCheckedChange = { alwaysMinimizeLabel = it })
        Text("Show placeholder even when unfocused")
    }
    Spacer(Modifier.height(16.dp))
    TextField(
        state = rememberTextFieldState(),
        lineLimits = TextFieldLineLimits.SingleLine,
        label = { Text("Label") },
        labelPosition = TextFieldLabelPosition.Attached(alwaysMinimize = alwaysMinimizeLabel),
        prefix = { Text("www.") },
        suffix = { Text(".com") },
        placeholder = { Text("google") },
    )
}

To handle the error input state, use isError parameter:

import androidx.compose.foundation.layout.Row
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.LaunchedEffect
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.runtime.saveable.rememberSaveable
import androidx.compose.runtime.snapshotFlow
import androidx.compose.ui.Modifier
import androidx.compose.ui.semantics.clearAndSetSemantics
import androidx.compose.ui.semantics.error
import androidx.compose.ui.semantics.maxTextLength
import androidx.compose.ui.semantics.semantics

val errorMessage = "Text input too long"
val state = rememberTextFieldState()
var isError by rememberSaveable { mutableStateOf(false) }
val charLimit = 10

fun validate(text: CharSequence) {
    isError = text.length > charLimit
}

LaunchedEffect(Unit) {
    // Run validation whenever text value changes
    snapshotFlow { state.text }.collect { validate(it) }
}
TextField(
    state = state,
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text(if (isError) "Username*" else "Username") },
    supportingText = {
        Row {
            Text(if (isError) errorMessage else "", Modifier.clearAndSetSemantics {})
            Spacer(Modifier.weight(1f))
            Text("Limit: ${state.text.length}/$charLimit")
        }
    },
    isError = isError,
    onKeyboardAction = { validate(state.text) },
    modifier =
        Modifier.semantics {
            maxTextLength = charLimit
            // Provide localized description of the error
            if (isError) error(errorMessage)
        }
)

Additionally, you may provide additional message at the bottom:

import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember

TextField(
    state = rememberTextFieldState(),
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
    supportingText = {
        Text("Supporting text that is long and perhaps goes onto another line.")
    },
)

You can change the content padding to create a dense text field:

import androidx.compose.foundation.layout.PaddingValues
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.heightIn
import androidx.compose.foundation.text.input.TextFieldLineLimits
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

TextField(
    state = rememberTextFieldState(),
    lineLimits = TextFieldLineLimits.SingleLine,
    label = { Text("Label") },
    // Need to set a min height using `heightIn` to override the default
    modifier = Modifier.heightIn(min = 48.dp),
    contentPadding = PaddingValues(top = 4.dp, bottom = 4.dp, start = 12.dp, end = 12.dp),
)

Hiding a software keyboard on IME action performed:

import androidx.compose.foundation.text.KeyboardOptions
import androidx.compose.foundation.text.input.rememberTextFieldState
import androidx.compose.material3.Text
import androidx.compose.material3.TextField
import androidx.compose.runtime.remember
import androidx.compose.ui.platform.LocalSoftwareKeyboardController
import androidx.compose.ui.text.input.ImeAction

val keyboardController = LocalSoftwareKeyboardController.current
TextField(
    state = rememberTextFieldState(),
    label = { Text("Label") },
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    onKeyboardAction = { keyboardController?.hide() }
)
Parameters
state: TextFieldState

TextFieldState object that holds the internal editing state of the text field.
modifier: Modifier = Modifier

the Modifier to be applied to this text field.
enabled: Boolean = true

controls the enabled state of this text field. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
readOnly: Boolean = false

controls the editable state of the text field. When true, the text field cannot be modified. However, a user can focus it and copy text from it. Read-only text fields are usually used to display pre-filled forms that a user cannot edit.
textStyle: TextStyle = LocalTextStyle.current

the style to be applied to the input text. Defaults to LocalTextStyle.
labelPosition: TextFieldLabelPosition = TextFieldLabelPosition.Attached()

the position of the label. See TextFieldLabelPosition.
label: (@Composable TextFieldLabelScope.() -> Unit)? = null

the optional label to be displayed with this text field. The default text style uses Typography.bodySmall when minimized and Typography.bodyLarge when expanded.
placeholder: (@Composable () -> Unit)? = null

the optional placeholder to be displayed when the input text is empty. The default text style uses Typography.bodyLarge.
leadingIcon: (@Composable () -> Unit)? = null

the optional leading icon to be displayed at the beginning of the text field container.
trailingIcon: (@Composable () -> Unit)? = null

the optional trailing icon to be displayed at the end of the text field container.
prefix: (@Composable () -> Unit)? = null

the optional prefix to be displayed before the input text in the text field.
suffix: (@Composable () -> Unit)? = null

the optional suffix to be displayed after the input text in the text field.
supportingText: (@Composable () -> Unit)? = null

the optional supporting text to be displayed below the text field.
isError: Boolean = false

indicates if the text field's current value is in error. When true, the components of the text field will be displayed in an error color, and an error will be announced to accessibility services.
inputTransformation: InputTransformation? = null

optional InputTransformation that will be used to transform changes to the TextFieldState made by the user. The transformation will be applied to changes made by hardware and software keyboard events, pasting or dropping text, accessibility services, and tests. The transformation will not be applied when changing the state programmatically, or when the transformation is changed. If the transformation is changed on an existing text field, it will be applied to the next user edit. The transformation will not immediately affect the current state.
outputTransformation: OutputTransformation? = null

optional OutputTransformation that transforms how the contents of the text field are presented.
keyboardOptions: KeyboardOptions = KeyboardOptions.Default

software keyboard options that contains configuration such as KeyboardType and ImeAction.
onKeyboardAction: KeyboardActionHandler? = null

called when the user presses the action button in the input method editor (IME), or by pressing the enter key on a hardware keyboard. By default this parameter is null, and would execute the default behavior for a received IME Action e.g., ImeAction.Done would close the keyboard, ImeAction.Next would switch the focus to the next focusable item on the screen.
lineLimits: TextFieldLineLimits = TextFieldLineLimits.Default

whether the text field should be SingleLine, scroll horizontally, and ignore newlines; or MultiLine and grow and scroll vertically. If SingleLine is passed, all newline characters ('\n') within the text will be replaced with regular whitespace (' ').
onTextLayout: (Density.(getResult: () -> TextLayoutResult) -> Unit)? = null

Callback that is executed when the text layout becomes queryable. The callback receives a function that returns a TextLayoutResult if the layout can be calculated, or null if it cannot. The function reads the layout result from a snapshot state object, and will invalidate its caller when the layout result changes. A TextLayoutResult object contains paragraph information, size of the text, baselines and other details. Density scope is the one that was used while creating the given text layout.
scrollState: ScrollState = rememberScrollState()

scroll state that manages either horizontal or vertical scroll of the text field. If lineLimits is SingleLine, this text field is treated as single line with horizontal scroll behavior. Otherwise, the text field becomes vertically scrollable.
shape: Shape = TextFieldDefaults.shape

defines the shape of this text field's container.
colors: TextFieldColors = TextFieldDefaults.colors()

TextFieldColors that will be used to resolve the colors used for this text field in different states. See TextFieldDefaults.colors.
contentPadding: PaddingValues = if (label == null || labelPosition is TextFieldLabelPosition.Above) { TextFieldDefaults.contentPaddingWithoutLabel() } else { TextFieldDefaults.contentPaddingWithLabel() }

the padding applied to the inner text field that separates it from the surrounding elements of the text field. Note that the padding values may not be respected if they are incompatible with the text field's size constraints or layout. See TextFieldDefaults.contentPaddingWithLabel and TextFieldDefaults.contentPaddingWithoutLabel.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this text field. You can use this to change the text field's appearance or preview the text field in different states. Note that if null is provided, interactions will still happen internally.

Toggle button is a toggleable button that switches between primary and tonal colors depending on checked's value. It also morphs between the three shapes provided in shapes depending on the state of the interaction with the toggle button as long as the three shapes provided our CornerBasedShapes. If a shape in shapes isn't a CornerBasedShape, then toggle button will toggle between the ButtonShapes according to user interaction.

Toggle button is a toggleable button that switches between primary and tonal colors depending on checked's value. It also morphs between the three shapes provided in shapes depending on the state of the interaction with the toggle button as long as the three shapes provided our CornerBasedShapes. If a shape in shapes isn't a CornerBasedShape, then toggle button will toggle between the ButtonShapes according to user interaction.

TODO link to an image when available

tonal toggle buttons are medium-emphasis buttons that is an alternative middle ground between default ToggleButtons (filled) and OutlinedToggleButtons. They can be used in contexts where lower-priority button requires slightly more emphasis than an outline would give. Tonal toggle buttons use the secondary color mapping.

Parameters
positionProvider: PopupPositionProvider

PopupPositionProvider that will be used to place the tooltip relative to the anchor content.
tooltip: @Composable TooltipScope.() -> Unit

the composable that will be used to populate the tooltip's content.
state: TooltipState

handles the state of the tooltip's visibility.
modifier: Modifier = Modifier

the Modifier to be applied to the TooltipBox.
focusable: Boolean = true

Boolean that determines if the tooltip is focusable. When true, the tooltip will consume touch events while it's shown and will have accessibility focus move to the first element of the component. When false, the tooltip won't consume touch events while it's shown but assistive-tech users will need to swipe or drag to get to the first element of the component.
enableUserInput: Boolean = true

Boolean which determines if this TooltipBox will handle long press and mouse hover to trigger the tooltip through the state provided.
content: @Composable () -> Unit

the composable that the tooltip will anchor to.

TooltipState

Cmn 
@ExperimentalMaterial3Api
fun TooltipState(
    initialIsVisible: Boolean = false,
    isPersistent: Boolean = true,
    mutatorMutex: MutatorMutex = BasicTooltipDefaults.GlobalMutatorMutex
): TooltipState

Constructor extension function for TooltipState

Parameters
initialIsVisible: Boolean = false

the initial value for the tooltip's visibility when drawn.
isPersistent: Boolean = true

Boolean that determines if the tooltip associated with this will be persistent or not. If isPersistent is true, then the tooltip will only be dismissed when the user clicks outside the bounds of the tooltip or if TooltipState.dismiss is called. When isPersistent is false, the tooltip will dismiss after a short duration. Ideally, this should be set to true when there is actionable content being displayed within a tooltip.
mutatorMutex: MutatorMutex = BasicTooltipDefaults.GlobalMutatorMutex

MutatorMutex used to ensure that for all of the tooltips associated with the mutator mutex, only one will be shown on the screen at any time.

Parameters
title: @Composable () -> Unit

the title to be displayed in the top app bar
modifier: Modifier = Modifier

the Modifier to be applied to this top app bar
navigationIcon: @Composable () -> Unit = {}

the navigation icon displayed at the start of the top app bar. This should typically be an IconButton or IconToggleButton.
actions: @Composable RowScope.() -> Unit = {}

the actions displayed at the end of the top app bar. This should typically be IconButtons. The default layout here is a Row, so icons inside will be placed horizontally.
expandedHeight: Dp = TopAppBarDefaults.TopAppBarExpandedHeight

this app bar's height. When a specified scrollBehavior causes the app bar to collapse or expand, this value will represent the maximum height that the bar will be allowed to expand. This value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.TopAppBarExpandedHeight.
windowInsets: WindowInsets = TopAppBarDefaults.windowInsets

a window insets that app bar will respect.
colors: TopAppBarColors = TopAppBarDefaults.topAppBarColors()

TopAppBarColors that will be used to resolve the colors used for this top app bar in different states. See TopAppBarDefaults.topAppBarColors.
scrollBehavior: TopAppBarScrollBehavior? = null

a TopAppBarScrollBehavior which holds various offset values that will be applied by this top app bar to set up its height and colors. A scroll behavior is designed to work in conjunction with a scrolled content to change the top app bar appearance as the content scrolls. See TopAppBarScrollBehavior.nestedScrollConnection.

Parameters
title: @Composable () -> Unit

the title to be displayed in the top app bar
subtitle: @Composable () -> Unit

the subtitle to be displayed in the top app bar
modifier: Modifier = Modifier

the Modifier to be applied to this top app bar
navigationIcon: @Composable () -> Unit = {}

the navigation icon displayed at the start of the top app bar. This should typically be an IconButton or IconToggleButton.
actions: @Composable RowScope.() -> Unit = {}

the actions displayed at the end of the top app bar. This should typically be IconButtons. The default layout here is a Row, so icons inside will be placed horizontally.
titleHorizontalAlignment: TopAppBarTitleAlignment = TopAppBarTitleAlignment.Start

the horizontal alignment of the title and subtitle
expandedHeight: Dp = TopAppBarDefaults.TopAppBarExpandedHeight

this app bar's height. When a specified scrollBehavior causes the app bar to collapse or expand, this value will represent the maximum height that the bar will be allowed to expand. This value must be specified and finite, otherwise it will be ignored and replaced with TopAppBarDefaults.TopAppBarExpandedHeight.
windowInsets: WindowInsets = TopAppBarDefaults.windowInsets

a window insets that app bar will respect.
colors: TopAppBarColors = TopAppBarDefaults.topAppBarColors()

TopAppBarColors that will be used to resolve the colors used for this top app bar in different states. See TopAppBarDefaults.topAppBarColors.
scrollBehavior: TopAppBarScrollBehavior? = null

a TopAppBarScrollBehavior which holds various offset values that will be applied by this top app bar to set up its height and colors. A scroll behavior is designed to work in conjunction with a scrolled content to change the top app bar appearance as the content scrolls. See TopAppBarScrollBehavior.nestedScrollConnection.

TriStateCheckbox

Cmn 
@Composable
fun TriStateCheckbox(
    state: ToggleableState,
    onClick: (() -> Unit)?,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    colors: CheckboxColors = CheckboxDefaults.colors(),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design checkbox parent.

Checkboxes can have a parent-child relationship with other checkboxes. When the parent checkbox is checked, all child checkboxes are checked. If a parent checkbox is unchecked, all child checkboxes are unchecked. If some, but not all, child checkboxes are checked, the parent checkbox becomes an indeterminate checkbox.

Parameters
state: ToggleableState

whether this checkbox is checked, unchecked, or in an indeterminate state
onClick: (() -> Unit)?

called when this checkbox is clicked. If null, then this checkbox will not be interactable, unless something else handles its input events and updates its state.
modifier: Modifier = Modifier

the Modifier to be applied to this checkbox
enabled: Boolean = true

controls the enabled state of this checkbox. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
colors: CheckboxColors = CheckboxDefaults.colors()

CheckboxColors that will be used to resolve the colors used for this checkbox in different states. See CheckboxDefaults.colors.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this checkbox. You can use this to change the checkbox's appearance or preview the checkbox in different states. Note that if null is provided, interactions will still happen internally.

Material design wide navigation rail.

Wide navigation rails provide access to primary destinations in apps when using tablet and desktop screens.

The wide navigation rail should be used to display multiple WideNavigationRailItems, each representing a singular app destination, and, optionally, a header containing a menu button, a FloatingActionButton, and/or a logo. Each destination is typically represented by an icon and a text label.

The WideNavigationRail is collapsed by default, but it also supports being expanded via the value of expanded. When collapsed, the rail should display three to seven navigation items. A simple example looks like:

import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material.icons.filled.Home
import androidx.compose.material.icons.filled.Star
import androidx.compose.material.icons.outlined.FavoriteBorder
import androidx.compose.material.icons.outlined.Home
import androidx.compose.material.icons.outlined.StarBorder
import androidx.compose.material3.Icon
import androidx.compose.material3.NavigationRail
import androidx.compose.material3.NavigationRailItem
import androidx.compose.material3.Text
import androidx.compose.material3.WideNavigationRail
import androidx.compose.material3.WideNavigationRailItem
import androidx.compose.runtime.mutableIntStateOf
import androidx.compose.runtime.remember

var selectedItem by remember { mutableIntStateOf(0) }
val items = listOf("Home", "Search", "Settings")
val selectedIcons = listOf(Icons.Filled.Home, Icons.Filled.Favorite, Icons.Filled.Star)
val unselectedIcons =
    listOf(Icons.Outlined.Home, Icons.Outlined.FavoriteBorder, Icons.Outlined.StarBorder)
WideNavigationRail {
    items.forEachIndexed { index, item ->
        WideNavigationRailItem(
            icon = {
                Icon(
                    if (selectedItem == index) selectedIcons[index] else unselectedIcons[index],
                    contentDescription = null
                )
            },
            label = { Text(item) },
            selected = selectedItem == index,
            onClick = { selectedItem = index }
        )
    }
}

When expanded, the rail should display at least three navigation items. A simple example looks like:

import androidx.compose.material.icons.Icons
import androidx.compose.material.icons.filled.Favorite
import androidx.compose.material.icons.filled.Home
import androidx.compose.material.icons.filled.Star
import androidx.compose.material.icons.outlined.FavoriteBorder
import androidx.compose.material.icons.outlined.Home
import androidx.compose.material.icons.outlined.StarBorder
import androidx.compose.material3.Icon
import androidx.compose.material3.NavigationRail
import androidx.compose.material3.NavigationRailItem
import androidx.compose.material3.Text
import androidx.compose.material3.WideNavigationRail
import androidx.compose.material3.WideNavigationRailItem
import androidx.compose.runtime.mutableIntStateOf
import androidx.compose.runtime.remember

var selectedItem by remember { mutableIntStateOf(0) }
val items = listOf("Home", "Search", "Settings")
val selectedIcons = listOf(Icons.Filled.Home, Icons.Filled.Favorite, Icons.Filled.Star)
val unselectedIcons =
    listOf(Icons.Outlined.Home, Icons.Outlined.FavoriteBorder, Icons.Outlined.StarBorder)
WideNavigationRail(expanded = true) {
    items.forEachIndexed { index, item ->
        WideNavigationRailItem(
            railExpanded = true,
            icon = {
                Icon(
                    if (selectedItem == index) selectedIcons[index] else unselectedIcons[index],
                    contentDescription = null
                )
            },
            label = { Text(item) },
            selected = selectedItem == index,
            onClick = { selectedItem = index }
        )
    }
}

The WideNavigationRail also supports automatically animating between the collapsed and expanded values. That can be done like so:

Finally, the WideNavigationRail supports setting a WideNavigationRailArrangement for the items, so that the items can be grouped at the top (the default), at the middle, or at the bottom of the rail. The header will always be at the top.

See WideNavigationRailItem for configuration specific to each item, and not the overall WideNavigationRail component.

Parameters
modifier: Modifier = Modifier

the Modifier to be applied to this wide navigation rail
expanded: Boolean = false

whether this wide navigation rail is expanded or collapsed (default).
shape: Shape = WideNavigationRailDefaults.containerShape

defines the shape of this wide navigation rail's container.
colors: WideNavigationRailColors = WideNavigationRailDefaults.colors()

WideNavigationRailColors that will be used to resolve the colors used for this wide navigation rail. See WideNavigationRailDefaults.colors
header: (@Composable () -> Unit)? = null

optional header that may hold a FloatingActionButton or a logo
windowInsets: WindowInsets = WideNavigationRailDefaults.windowInsets

a window insets of the wide navigation rail
arrangement: WideNavigationRailArrangement = WideNavigationRailDefaults.Arrangement

the WideNavigationRailArrangement of this wide navigation rail
content: @Composable () -> Unit

WideNavigationRailItem

Cmn 
@ExperimentalMaterial3ExpressiveApi
@Composable
fun WideNavigationRailItem(
    selected: Boolean,
    onClick: () -> Unit,
    icon: @Composable () -> Unit,
    label: (@Composable () -> Unit)?,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    railExpanded: Boolean = false,
    iconPosition: NavigationItemIconPosition = WideNavigationRailItemDefaults.iconPositionFor(railExpanded),
    colors: NavigationItemColors = WideNavigationRailItemDefaults.colors(),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design wide navigation rail item.

It's recommend for navigation items to always have a text label. A WideNavigationRailItem always displays labels (if they exist) when selected and unselected.

The WideNavigationRailItem supports two different icon positions, top and start, which is controlled by the iconPosition param:

  • If the icon position is NavigationItemIconPosition.Top the icon will be displayed above the label. This configuration should be used with collapsed wide navigation rails.

  • If the icon position is NavigationItemIconPosition.Start the icon will be displayed to the start of the label. This configuration should be used with expanded wide navigation rails.

However, if an animated item is desired, the iconPosition can be controlled via the expanded value of the associated WideNavigationRail. By default, it'll use the railExpanded to follow the configuration described above.

Parameters
selected: Boolean

whether this item is selected
onClick: () -> Unit

called when this item is clicked
icon: @Composable () -> Unit

icon for this item, typically an Icon
label: (@Composable () -> Unit)?

text label for this item
modifier: Modifier = Modifier

the Modifier to be applied to this item
enabled: Boolean = true

controls the enabled state of this item. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
railExpanded: Boolean = false

whether the associated WideNavigationRail is expanded or collapsed
iconPosition: NavigationItemIconPosition = WideNavigationRailItemDefaults.iconPositionFor(railExpanded)

the NavigationItemIconPosition for the icon
colors: NavigationItemColors = WideNavigationRailItemDefaults.colors()

NavigationItemColors that will be used to resolve the colors used for this item in different states. See WideNavigationRailItemDefaults.colors
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this item. You can use this to change the item's appearance or preview the item in different states. Note that if null is provided, interactions will still happen internally.

contentColorFor

Cmn 
@Composable
fun contentColorFor(backgroundColor: Color): Color

The Material color system contains pairs of colors that are typically used for the background and content color inside a component. For example, a Button typically uses primary for its background, and onPrimary for the color of its content (usually text or iconography).

This function tries to match the provided backgroundColor to a 'background' color in this ColorScheme, and then will return the corresponding color used for content. For example, when backgroundColor is ColorScheme.primary, this will return ColorScheme.onPrimary.

If backgroundColor does not match a background color in the theme, this will return the current value of LocalContentColor as a best-effort color.

Returns
Color

the matching content color for backgroundColor. If backgroundColor is not present in the theme's ColorScheme, then returns the current value of LocalContentColor.

ripple

Cmn 
fun ripple(
    bounded: Boolean = true,
    radius: Dp = Dp.Unspecified,
    color: Color = Color.Unspecified
): IndicationNodeFactory

Creates a Ripple using the provided values and values inferred from the theme.

A Ripple is a Material implementation of Indication that expresses different Interactions by drawing ripple animations and state layers.

A Ripple responds to PressInteraction.Press by starting a new ripple animation, and responds to other Interactions by showing a fixed state layer with varying alpha values depending on the Interaction.

MaterialTheme provides Ripples using androidx.compose.foundation.LocalIndication, so a Ripple will be used as the default Indication inside components such as androidx.compose.foundation.clickable and androidx.compose.foundation.indication, in addition to Material provided components that use a Ripple as well.

You can also explicitly create a Ripple and provide it to custom components in order to change the parameters from the default, such as to create an unbounded ripple with a fixed size.

To create a Ripple with a manually defined color that can change over time, see the other ripple overload with a ColorProducer parameter. This will avoid unnecessary recompositions when changing the color, and preserve existing ripple state when the color changes.

Parameters
bounded: Boolean = true

If true, ripples are clipped by the bounds of the target layout. Unbounded ripples always animate from the target layout center, bounded ripples animate from the touch position.
radius: Dp = Dp.Unspecified

the radius for the ripple. If Dp.Unspecified is provided then the size will be calculated based on the target layout size.
color: Color = Color.Unspecified

the color of the ripple. This color is usually the same color used by the text or iconography in the component. This color will then have RippleDefaults.RippleAlpha applied to calculate the final color used to draw the ripple. If Color.Unspecified is provided the color used will be LocalContentColor instead.

ripple

Cmn 
fun ripple(
    color: ColorProducer,
    bounded: Boolean = true,
    radius: Dp = Dp.Unspecified
): IndicationNodeFactory

Creates a Ripple using the provided values and values inferred from the theme.

A Ripple is a Material implementation of Indication that expresses different Interactions by drawing ripple animations and state layers.

A Ripple responds to PressInteraction.Press by starting a new ripple animation, and responds to other Interactions by showing a fixed state layer with varying alpha values depending on the Interaction.

MaterialTheme provides Ripples using androidx.compose.foundation.LocalIndication, so a Ripple will be used as the default Indication inside components such as androidx.compose.foundation.clickable and androidx.compose.foundation.indication, in addition to Material provided components that use a Ripple as well.

You can also explicitly create a Ripple and provide it to custom components in order to change the parameters from the default, such as to create an unbounded ripple with a fixed size.

To create a Ripple with a static color, see the ripple overload with a Color parameter. This overload is optimized for Ripples that have dynamic colors that change over time, to reduce unnecessary recompositions.

Parameters
color: ColorProducer

the color of the ripple. This color is usually the same color used by the text or iconography in the component. This color will then have RippleDefaults.RippleAlpha applied to calculate the final color used to draw the ripple. If you are creating this ColorProducer outside of composition (where it will be automatically remembered), make sure that its instance is stable (such as by remembering the object that holds it), or remember the returned ripple object to make sure that ripple nodes are not being created each recomposition.
bounded: Boolean = true

If true, ripples are clipped by the bounds of the target layout. Unbounded ripples always animate from the target layout center, bounded ripples animate from the touch position.
radius: Dp = Dp.Unspecified

the radius for the ripple. If Dp.Unspecified is provided then the size will be calculated based on the target layout size.

NavigationBarItem

Cmn 
@Composable
fun RowScope.NavigationBarItem(
    selected: Boolean,
    onClick: () -> Unit,
    icon: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    label: (@Composable () -> Unit)? = null,
    alwaysShowLabel: Boolean = true,
    colors: NavigationBarItemColors = NavigationBarItemDefaults.colors(),
    interactionSource: MutableInteractionSource? = null
): Unit

Material Design navigation bar item.

Navigation bars offer a persistent and convenient way to switch between primary destinations in an app.

The recommended configuration for a NavigationBarItem depends on how many items there are inside a NavigationBar:

  • Three destinations: Display icons and text labels for all destinations.

  • Four destinations: Active destinations display an icon and text label. Inactive destinations display icons, and text labels are recommended.

  • Five destinations: Active destinations display an icon and text label. Inactive destinations use icons, and use text labels if space permits.

A NavigationBarItem always shows text labels (if it exists) when selected. Showing text labels if not selected is controlled by alwaysShowLabel.

Parameters
selected: Boolean

whether this item is selected
onClick: () -> Unit

called when this item is clicked
icon: @Composable () -> Unit

icon for this item, typically an Icon
modifier: Modifier = Modifier

the Modifier to be applied to this item
enabled: Boolean = true

controls the enabled state of this item. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
label: (@Composable () -> Unit)? = null

optional text label for this item
alwaysShowLabel: Boolean = true

whether to always show the label for this item. If false, the label will only be shown when this item is selected.
colors: NavigationBarItemColors = NavigationBarItemDefaults.colors()

NavigationBarItemColors that will be used to resolve the colors used for this item in different states. See NavigationBarItemDefaults.colors.
interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this item. You can use this to change the item's appearance or preview the item in different states. Note that if null is provided, interactions will still happen internally.

contentColorFor

Cmn 
fun ColorScheme.contentColorFor(backgroundColor: Color): Color

The Material color system contains pairs of colors that are typically used for the background and content color inside a component. For example, a Button typically uses primary for its background, and onPrimary for the color of its content (usually text or iconography).

This function tries to match the provided backgroundColor to a 'background' color in this ColorScheme, and then will return the corresponding color used for content. For example, when backgroundColor is ColorScheme.primary, this will return ColorScheme.onPrimary.

If backgroundColor does not match a background color in the theme, this will return Color.Unspecified.

Returns
Color

the matching content color for backgroundColor. If backgroundColor is not present in the theme's ColorScheme, then returns Color.Unspecified.

minimumInteractiveComponentSize

Cmn 
fun Modifier.minimumInteractiveComponentSize(): Modifier

Reserves at least 48.dp in size to disambiguate touch interactions if the element would measure smaller.

https://m3.material.io/foundations/designing/structure#dab862b1-e042-4c40-b680-b484b9f077f6

This uses the Material recommended minimum size of 48.dp x 48.dp, which may not the same as the system enforced minimum size. The minimum clickable / touch target size (48.dp by default) is controlled by the system via ViewConfiguration and automatically expanded at the touch input layer.

This modifier is not needed for touch target expansion to happen. It only affects layout, to make sure there is adequate space for touch target expansion.

Because layout constraints are affected by modifier order, for this modifier to take effect, it must come before any size modifiers on the element that might limit its constraints.

opticalCentering

Cmn 
@ExperimentalMaterial3ExpressiveApi
fun Modifier.opticalCentering(
    shape: CornerBasedShape,
    basePadding: PaddingValues
): Modifier

Modifier that centers the content depending on the shape provided. It will increase or decrease the start padding to better center the content depending on the corner radii of the provided shape. This is meant to be used with asymmetric shapes, the modifier will not do anything to the content if the shape provided is symmetric.

Parameters
shape: CornerBasedShape

the CornerBasedShape that the content should be adjusted to so that the content is more centered within the shape.
basePadding: PaddingValues

the initial content padding that would have been applied to the content before correcting for the corner radii of the shape.

surfaceColorAtElevation

Cmn 
fun ColorScheme.surfaceColorAtElevation(elevation: Dp): Color

Computes the surface tonal color at different elevation levels e.g. surface1 through surface5.

Parameters
elevation: Dp

Elevation value used to compute alpha of the color overlay layer.
Returns
Color

the ColorScheme.surface color with an alpha of the ColorScheme.surfaceTint color overlaid on top of it.

toPath

Cmn 
@ExperimentalMaterial3ExpressiveApi
@Composable
fun RoundedPolygon.toPath(startAngle: Int = 0): Path

Returns a Path that is remembered across compositions for this RoundedPolygon.

Parameters
startAngle: Int = 0

the angle (in degrees) from which to begin drawing the generated path. By default, it is set to 0 degrees, meaning the Path begins drawing at the 3 o'clock position. The returned path is rotated by this angle around the RoundedPolygon's centroid (centerX, centerY).

toPath

Cmn 
@ExperimentalMaterial3ExpressiveApi
fun Morph.toPath(progress: Float, path: Path = Path(), startAngle: Int = 0): Path

Returns a Path for this Morph.

Parameters
progress: Float

the Morph's progress
path: Path = Path()

a Path to rewind and set with the new path data. In case provided, this Path would be the returned one.
startAngle: Int = 0

the angle (in degrees) from which to begin drawing the generated path. By default, it is set to 0 degrees, meaning the Path begins drawing at the 3 o'clock position.

toShape

Cmn 
@ExperimentalMaterial3ExpressiveApi
@Composable
fun RoundedPolygon.toShape(startAngle: Int = 0): Shape

Returns a Shape that is remembered across compositions for this RoundedPolygon.

Parameters
startAngle: Int = 0

the angle (in degrees) from which to begin drawing the generated shape's path. By default, it is set to 0 degrees, meaning the shape's path begins drawing at the 3 o'clock position. The returned path is rotated by this angle around the RoundedPolygon's centroid (centerX, centerY).

Top-level properties

LocalAbsoluteTonalElevation

Cmn 
val LocalAbsoluteTonalElevation: ProvidableCompositionLocal<Dp>

CompositionLocal containing the current absolute elevation provided by Surface components. This absolute elevation is a sum of all the previous elevations. Absolute elevation is only used for calculating surface tonal colors, and is not used for drawing the shadow in a Surface.

LocalContentColor

Cmn 
val LocalContentColor: ProvidableCompositionLocal<Color>

CompositionLocal containing the preferred content color for a given position in the hierarchy. This typically represents the on color for a color in ColorScheme. For example, if the background color is ColorScheme.surface, this color is typically set to ColorScheme.onSurface.

This color should be used for any typography / iconography, to ensure that the color of these adjusts when the background color changes. For example, on a dark background, text should be light, and on a light background, text should be dark.

Defaults to Color.Black if no color has been explicitly set.

LocalMinimumInteractiveComponentEnforcement

Cmn
Added in 1.1.0
Deprecated in 1.3.0
@ExperimentalMaterial3Api
val LocalMinimumInteractiveComponentEnforcement: ProvidableCompositionLocal<Boolean>

CompositionLocal that configures whether Material components that have a visual size that is lower than the minimum touch target size for accessibility (such as Button) will include extra space outside the component to ensure that they are accessible. If set to false there will be no extra space, and so it is possible that if the component is placed near the edge of a layout / near to another component without any padding, there will not be enough space for an accessible touch target.

LocalMinimumInteractiveComponentSize

Cmn 
val LocalMinimumInteractiveComponentSize: ProvidableCompositionLocal<Dp>

CompositionLocal that configures the minimum touch target size for Material components (such as Button) to ensure they are accessible. If a component has a visual size that is lower than the minimum touch target size, extra space outside the component will be included. If set to 0.dp, there will be no extra space, and so it is possible that if the component is placed near the edge of a layout / near to another component without any padding, there will not be enough space for an accessible touch target.

LocalRippleConfiguration

Cmn 
val LocalRippleConfiguration: ProvidableCompositionLocal<RippleConfiguration?>

CompositionLocal used for providing RippleConfiguration down the tree. This acts as a tree-local 'override' for ripples used inside components that you cannot directly control, such as to change the color of a specific component's ripple, or disable it entirely by providing null.

In most cases you should rely on the default theme behavior for consistency with other components

  • this exists as an escape hatch for individual components and is not intended to be used for full theme customization across an application. For this use case you should instead build your own custom ripple that queries your design system theme values directly using createRippleModifierNode.

LocalTextStyle

Cmn 
val LocalTextStyle: ProvidableCompositionLocal<TextStyle>

CompositionLocal containing the preferred TextStyle that will be used by Text components by default. To set the value for this CompositionLocal, see ProvideTextStyle which will merge any missing TextStyle properties with the existing TextStyle set in this CompositionLocal.

ProvideTextStyle

LocalTonalElevationEnabled

Cmn 
val LocalTonalElevationEnabled: ProvidableCompositionLocal<Boolean>

Composition Local used to check if ColorScheme.applyTonalElevation will be applied down the tree.

Setting this value to false will cause all subsequent surfaces down the tree to not apply tonalElevation.

Extension properties

isPm

Cmn 
val TimePickerState.isPm: Boolean

Indicates whether the selected time falls within the period from 12 PM inclusive to 12 AM non inclusive.
