Hi, is there a way to have an effect equivalent to `clipChildren=false`? I have a `Column` composed of scrollable `LazyColumnFor` + `FloatingActionButton` and I want the scrollable column to be seen behind the FAB. But scrolling should end just above the FAB, not below

Add an empty item at the bottom of your list equal to the height of the FAB?

But I need to calculate the size of the FAB then, right? I think this is not done very easely in Compose

it’s really easy: <https://developer.android.com/reference/kotlin/androidx/compose/ui/package-summary#onpositioned_1>

I guess there is also a need to add some `MutableState` variable which stores the laid out height of FAB (modified by `onPositioned`). And then the item list should be comprised with original list + one special item which get its height updated. And then in `LazyColumnFor`’s `itemContent` we should add some kind of `when` which inspects what kind of item we got to choose the right composable. Please correct me if I overcomplicated something. Oh boy this is hard :sweat_smile:

That sounds right. I would expect this to get easier eventually, the lazy column APIs are still pretty early, and the scaffold stuff is going through some changes too I believe.

<@U0KMMQA20> is it possible to see the issues? to get an idea what they are thinking for the future.
