I also want to migrate to Jetpack Compose, I created a component that is fixed at the bottom of screen and it has a section that expands on click.

When I used it in a compose activity, it worked fine, but when I used the same component in a old activity using ComposeView inside a ConstraintLayout it began flickering when it is expanding or contracting. Anyone can help me?

I created a minimal example of it happening here (video on README.md)

I think the problem is that your ComposeView is resizing while the animation is running: android:layout_height="wrap_content"

@Csaba Szugyiczki it makes sense, but how can I fix that? I can't make the height constant...

no idea, maybe you can try adding android:animateLayoutChanges="true" to the parent ViewGroup

Well, it didn't work...

android:layout_height="0dp" worked

strange 🙂 but glad it solved for you
