Can I somehow animate from wrap content to fill max width?

Try the

animateContentSize

Modifier, on the Composable that wraps your Composable on which you are changing from warp content to fillMaxWidth https://developer.android.com/jetpack/compose/animation#animateContentSize

Looks promising, I’m trying to test but it’s quite slow to build, I’ll report back, thanks! 😄

Awesome! Glad I could help 🙂
