FlowRow is a layout that fills items from left to right (ltr) in LTR layouts or right to left (rtl) in RTL layouts and when it runs out of space, moves to the next "row" or "line" positioned on the bottom, and then continues filling items until the items run out.

Example:

import androidx.compose.foundation.background
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.FlowRow
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.padding
import androidx.compose.foundation.layout.width
import androidx.compose.foundation.layout.wrapContentHeight
import androidx.compose.material.Text
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.text.font.FontWeight
import androidx.compose.ui.unit.dp
import androidx.compose.ui.unit.sp

Text(
    modifier =
        Modifier.fillMaxWidth(1f).padding(20.dp).wrapContentHeight(align = Alignment.Top),
    text = "Flow Row with weights",
    fontWeight = FontWeight.Bold,
)

FlowRow(
    Modifier.fillMaxWidth(1f).padding(20.dp).wrapContentHeight(align = Alignment.Top),
    horizontalArrangement = Arrangement.spacedBy(10.dp),
    verticalArrangement = Arrangement.spacedBy(20.dp),
    maxItemsInEachRow = 3,
) {
    repeat(20) {
        Box(
            Modifier.align(Alignment.CenterVertically)
                .width(50.dp)
                .height(50.dp)
                .weight(1f, true)
                .background(Color.Green)
        ) {
            Text(text = it.toString(), fontSize = 18.sp, modifier = Modifier.padding(3.dp))
        }
    }
}

When a Modifier RowScope.weight is provided, it scales the item based on the number items that fall on the row it was placed in.

Note that if two or more Text components are placed in a Row, normally they should be aligned by their first baselines. FlowRow as a general purpose container does not do it automatically so developers need to handle this manually. This is achieved by adding a RowScope.alignByBaseline modifier to every such Text component. By default this modifier aligns by androidx.compose.ui.layout.FirstBaseline. If, however, you need to align Texts by androidx.compose.ui.layout.LastBaseline for example, use a more general RowScope.alignBy modifier.

Parameters
modifier: Modifier = Modifier	The modifier to be applied to the Row.
horizontalArrangement: Arrangement.Horizontal = Arrangement.Start	The horizontal arrangement of the layout's children.
verticalArrangement: Arrangement.Vertical = Arrangement.Top	The vertical arrangement of the layout's virtual rows.
itemVerticalAlignment: Alignment.Vertical = Alignment.Top	The cross axis/vertical alignment of an item in the column.
maxItemsInEachRow: Int = Int.MAX_VALUE	The maximum number of items per row
maxLines: Int = Int.MAX_VALUE	The max number of rows
content: @Composable FlowRowScope.() -> Unit	The content as a RowScope

FlowRow is a layout that fills items from left to right (ltr) in LTR layouts or right to left (rtl) in RTL layouts and when it runs out of space, moves to the next "row" or "line" positioned on the bottom, and then continues filling items until the items run out.
