In my task I need draw over some items in LazyColumn and by some events animate them.

I am trying to reproduce RecyclerView.ItemDecoration.onDrawOver behavior

I almost done it, but I ran into a problem: rememberLazyListState has not changed on over scroll position changed on Android 12.

See attached video

Code:

@Composable
fun OverScrollBug() {
  val data = remember {
    mutableStateOf((0 until 100).map { it.toString() })
  }
  val lazyListState = rememberLazyListState()
  LazyColumn(
    content = {
      items(data.value, { it }) { item ->
        Text("item $item")
      }
    },
    state = lazyListState,
    modifier = Modifier
      .fillMaxSize()
      .drawWithCache {
        val items = lazyListState.layoutInfo.visibleItemsInfo
        onDrawBehind {
          items.forEach {
            drawRect(
              color = Color.Red,
              topLeft = Offset(0F, it.offset.toFloat()),
              size = Size(10.dp.toPx(), 10.dp.toPx())
            )
          }
        }
      }
  )
}

So we need possibility to listen/react on over scroll changes
