Snap to an index Lazyrow

Question

I am making a calendar with the help of a lazyRow. I now have the problem that I want the row to snap to the index after a certain scroll amount so it shouldn't be possible to be stuck in between indexes. Is there a way to do that?

    LazyRow(state = calendarViewModel.listState, modifier = Modifier.fillMaxWidth()) {
        calendarYears.forEach {
            items(it.months.count()) { index ->
                calendarViewModel.onEvent(CalendarEvent.ClickedMenuItem(index))
                CalendarRowItem(
                    modifier = Modifier.fillParentMaxWidth(),
                    calendarSize = it.months[index].amountOfDays,
                    initWeekday = it.months[index].startDayOfMonth.ordinal,
                    textColor = MaterialTheme.colors.secondaryVariant,
                    clickedColor = MaterialTheme.colors.primary,
                    textStyle = MaterialTheme.typography.body1
                )
            }
        }
    }

Starting with compose 1.3.0 you can use the FlingBehavior that performs snapping of items to a given position:

val state = rememberLazyListState()

LazyRow(
    modifier = Modifier.fillMaxSize(),
    verticalAlignment = Alignment.CenterVertically,
    state = state,
    flingBehavior = rememberSnapFlingBehavior(lazyListState = state)
) {
  //item content
}
