SelectionList

fun <T : Any, K : Any> UiScope.SelectionList(items: List<T>, keyOf: (T) -> K, state: SelectionListState<K>, viewportSize: IntSize, rowHeight: Int, canLoadLeading: Boolean = false, canLoadTrailing: Boolean = false, scrollRate: Int = 10, modifier: Modifier = Modifier.Empty, key: ElementKey<*>? = null, content: UiScope.(T) -> Unit)(source)
