sealed interface TransformingLazyColumnScope

Receiver scope which is used by TransformingLazyColumn.

Summary

Public functions
`Unit`	`item(key: Any?, contentType: Any?, content: @Composable TransformingLazyColumnItemScope.() -> Unit)` Adds a single item.
`Unit`	`items( count: Int, key: ((index: Int) -> Any)?, contentType: (index: Int) -> Any, content: @Composable TransformingLazyColumnItemScope.(index: Int) -> Unit )` Adds `count` items.

Extension functions
`inline Unit`	`<T : Any?> TransformingLazyColumnScope.items( items: List<T>, noinline key: ((item) -> Any)?, noinline contentType: (item) -> Any, crossinline itemContent: @Composable TransformingLazyColumnItemScope.(item) -> Unit )` Adds a list of items.
`inline Unit`	`<T : Any?> TransformingLazyColumnScope.itemsIndexed( items: List<T>, noinline key: ((index: Int, item) -> Any)?, crossinline contentType: (index: Int, item) -> Any, crossinline itemContent: @Composable TransformingLazyColumnItemScope.(index: Int, item) -> Unit )` Adds a list of items where the content of an item is aware of its index.

Public functions

item

Added in 1.5.0-alpha05

fun item(key: Any? = null, contentType: Any? = null, content: @Composable TransformingLazyColumnItemScope.() -> Unit): Unit

Adds a single item.

Parameters
`key: Any? = null`	A stable and unique key representing the item. Using the same key for multiple items in the `TransformingLazyColumn` is not allowed. Type of the key should be saveable via Bundle on Android. If null is passed the position in the `TransformingLazyColumn` will represent the key. When you specify the key the scroll position will be maintained based on the key, which means if you add/remove items before the current visible item the item with the given key will be kept as the first visible one.
`contentType: Any? = null`	The type of the content of this item. The item compositions of the same type could be reused more efficiently. Note that null is a valid type and items of such type will be considered compatible.
`content: @Composable TransformingLazyColumnItemScope.() -> Unit`	The content of the item.

items

Added in 1.5.0-alpha05

fun items(
    count: Int,
    key: ((index: Int) -> Any)? = null,
    contentType: (index: Int) -> Any = { null },
    content: @Composable TransformingLazyColumnItemScope.(index: Int) -> Unit
): Unit

Adds count items.

Parameters
`count: Int`	The number of items to add to the `TransformingLazyColumn`.
`key: ((index: Int) -> Any)? = null`	A factory of stable and unique keys representing the item. Using the same key for multiple items in the `TransformingLazyColumn` is not allowed.
`contentType: (index: Int) -> Any = { null }`	A factory of the content types for the item. The item compositions of the same type could be reused more efficiently. Note that null is a valid type and items of such type will be considered compatible.
`content: @Composable TransformingLazyColumnItemScope.(index: Int) -> Unit`	The content displayed by a single item.

Parameters

    crossinline contentType: (index: Int, item) -> Any = { _, _ -> null },
    crossinline itemContent: @Composable TransformingLazyColumnItemScope.(index: Int, item) -> Unit
): Unit

Adds a list of items where the content of an item is aware of its index.

Parameters
`items: List<T>`	the data list
`noinline key: ((index: Int, item) -> Any)? = null`	a factory of stable and unique keys representing the item. Using the same key for multiple items in the `TransformingLazyColumn` is not allowed. Type of the key should be saveable via Bundle on Android. If null is passed the position in the list will represent the key. When you specify the key the scroll position will be maintained based on the key, which means if you add/remove items before the current visible item the item with the given key will be kept as the first visible one.
`crossinline contentType: (index: Int, item) -> Any = { _, _ -> null }`	a factory of the content types for the item. The item compositions of the same type could be reused more efficiently. Note that null is a valid type and items of such type will be considered compatible.
