LoadMoreFooter
fun LoadMoreFooter(isLoadingMore: Boolean, onLoadMore: () -> Unit, modifier: Modifier = Modifier, loadingLabel: String = "Loading more")
The last item of an infinite-scrolling lazy list. Each time it enters composition (scrolls into view) it calls onLoadMore; while isLoadingMore it shows a spinner named loadingLabel and announced politely. Guard against duplicate requests in onLoadMore, and stop emitting the footer when there is nothing left to load.
