Yes, we plan on supporting scale as a built-in Enter/ExitTransition. Before that we need to work through the implications of scale on slide/expand/shrink, and explore possibilities of having the scaled size affect parents.
In the meantime, you could workaround this by creating scale enter/exit animation in the content using the AnimatedVisibilityScope#transition. Here is an example:

Thank you for quick response.
For some use cases, AnimatedVisibility might be helpful. Unfortunately, however, my use case requires both fade and scale transitions. So I will wait for this news.
Have a good day.

Description
New AnimatedContent composable is introduced in compose-animation 1.0.0-beta09. AnimatedContent composable is cool feature and helps to implement transitions concisely. Thank you very much for that.
But, in EnterExitTransition.kt, TransitionData is limited to fade, slide, and changeSize only. So I can't implement material motions using AnimatedContent.
Therefore, I'd like to ask you one thing. Do you have any plans to supports scale function more?
