Has someone tried nested VerticalScroller, Is it a lot laggy.

[Bruno_]

@Composable
fun PagedVerticalScroller(
    onNextPage: (page: Int) -> Unit,
    child: @Composable() () -> Unit
) {
    var currentPage = 0
    val scrollerPosition: ScrollerPosition = +memo { ScrollerPosition() }

    VerticalScroller(scrollerPosition, { pos: Px, maxPos: Px ->
        scrollerPosition.value = pos

        if (pos.value > maxPos.value - 500) {
            onNextPage(currentPage)
            currentPage++
        }
    }) {
        child()
    }
}

in onNextPage add elements to a ModelList to reload the component

in my case, i use rxjava so the function that loads more elements looks like this

private fun loadMoreAds(page: Int, pageSize: Int = 10) {
    flowable
        .skip((page * pageSize).toLong())
        .take(((page + 1) * pageSize).toLong())
        .toList()
        .doOnSuccess { modelList.addAll(it) }
        .subscribe()
}
