Extension functions

LazyListScope.items

inline fun <T : Any?> LazyListScope.items(
    items: Array<T>,
    noinline itemId: (item) -> Long = { LazyListScope.UnspecifiedItemId },
    crossinline itemContent: @Composable LazyItemScope.(item) -> Unit
): Unit

Adds an array of items.

Parameters
items: Array<T>

the data array
noinline itemId: (item) -> Long = { LazyListScope.UnspecifiedItemId }

a factory of stable and unique list item ids. Using the same itemId for multiple items in the array is not allowed. When you specify the itemId, the scroll position will be maintained based on the itemId, which means if you add/remove items before the current visible item the item with the given itemId will be kept as the first visible one.
crossinline itemContent: @Composable LazyItemScope.(item) -> Unit

the content displayed by a single item

LazyVerticalGridScope.items

inline fun <T : Any?> LazyVerticalGridScope.items(
    items: Array<T>,
    noinline itemId: (item) -> Long = { LazyVerticalGridScope.UnspecifiedItemId },
    crossinline itemContent: @Composable LazyItemScope.(item) -> Unit
): Unit

Adds an array of items.

Parameters
items: Array<T>

the data array
noinline itemId: (item) -> Long = { LazyVerticalGridScope.UnspecifiedItemId }

a factory of stable and unique list item ids. Using the same itemId for multiple items in the array is not allowed. When you specify the itemId, the scroll position will be maintained based on the itemId, which means if you add/remove items before the current visible item the item with the given itemId will be kept as the first visible one.
crossinline itemContent: @Composable LazyItemScope.(item) -> Unit

the content displayed by a single item

LazyListScope.items

inline fun <T : Any?> LazyListScope.items(
    items: List<T>,
    crossinline itemId: (item) -> Long = { LazyListScope.UnspecifiedItemId },
    crossinline itemContent: @Composable LazyItemScope.(item) -> Unit
): Unit

Adds a list of items.

Parameters
items: List<T>

the data list
crossinline itemId: (item) -> Long = { LazyListScope.UnspecifiedItemId }

a factory of stable and unique ids representing the item. The value may not be less than or equal to -2^62, as these values are reserved by the Glance API. Specifying the list item ids will maintain the scroll position through app widget updates in Android S and higher devices.
crossinline itemContent: @Composable LazyItemScope.(item) -> Unit

the content displayed by a single item

LazyVerticalGridScope.items
