Jetpack compose released with alpha version and I want to implement paging for the LazyColumnFor compose function. But I can't understand how we can do this because I can't find something to determine scroll position or something similar. Do we have this opportunity right now or this mechanism will be add in the future?
Pagination for the LazyColumnFor

There is, as of the initial alpha release, not currently a way to detect scroll position. It will be added later, though, with an API something like:
Column {
val state = rememberLazyListState()
Text("First item: ${state.firstVisibleItemIndex}")
LazyColumnFor(
(0..100).toList(),
Modifier.fillMaxWidth(),
state = state
) {
Text("$it", style = currentTextStyle().copy(fontSize = 40.sp))
}
}
This will (once that is merged) display the first visible scroll position in the list.
