Does anyone know if this exists for LazyColumn when scrolling up/down with long press?

[Hristijan]

or what would be the alternative of this function for LazyListState

fun LazyListState.gridItemKeyAtPosition(hitPoint: Offset): Int? =
        layoutInfo.visibleItemsInfo.find { itemInfo ->
            //todo itemInfo.size.toIntRect().contains(hitPoint.round() - itemInfo.offset)
        }?.key as? Int

That same function would work for LazyColumn

I think you could probably just apply the whole post as is to a column instead of a grid

Hey Ben, it doesn't work because size is not an offset, rather an int and I cannot find any documentation how to calculate this for a lazy column

[Ben Trengrove [G]]

So that size is your height, you can assume it's within the width of your item because the items take the full width. It will be something like 'hitPoint >= itemInfo.offset && hitPoint < itemInfo.offset + itemInfo.size'

[Hristijan]

you mean something like this

.firstOrNull { lazyListItemInfo ->
                hitPoint.y.toInt() in lazyListItemInfo.offset..lazyListItemInfo.offset + lazyListItemInfo.size }

?
