I googled a bunch, but I couldn't find an answer to my question: How do you get the layed out height (or width) of a Compose component? I'd like to use the height of a LazyColunnFor to see if a ListItem is in the center of it (and scale it accordingly, based on how far away the ListItem is from that center).

There's a

onSizeChanged

modifier that you can use, and store the result in a mutableState

Quick example:

var height by remember { mutableStateOf(0) }
LazyColumnFor(
    modifier = Modifier.onSizeChanged {
        height = it.height
    }
)

Thank you!
