I’m trying to create a

Column

with a

VerticalScrollBar

that grows with its contents until it reaches the maximum available space and then becomes scrollable. The code looks approximately like this:

Box{
    Column(
        modifier = Modifier.verticalScroll(scrollState)
    ) {
        ...
    }
    VerticalScrollbar(
        modifier = Modifier.align(Alignment.CenterEnd).matchParentSize()
    )
}

Without the scrollbar, it works fine. Unfortunately, as soon as I add the scrollbar, it stretches the

Box

to fill all the available height. It doesn’t seem to respect the

matchParentSize

modifier.

You might be able to solve this with

Modifier.height(IntrinsicSize.Min)

on the Box. Manually measuring usually takes two compositions to get things done, which may result in subtle jank. Your case is somewhat similar to the official exampe: https://developer.android.com/jetpack/compose/layouts/intrinsic-measurements#intrinsics-in-action
