Has anyone requested Enter/ExitTransitions to scale content?

[tad]

Trying to implement shared Z-axis transitions from https://material.io/design/motion/the-motion-system.html#shared-axis

[tad]

But it appears that AnimatedContent and AnimatedVisibility are working against me

For now you could add a scale animation to the transition provided in AnimatedVisibilityScope like the example here: https://developer.android.com/reference/kotlin/androidx/compose/animation/AnimatedVisibilityScope

Yep, the main problem I have is that I need a different animation for "pushing" vs. "popping" a composable. I get both initialState and targetState to choose the correct ContentTransform, but I only get the current state in the AnimatedVisibilityScope.

So I would need to maintain my own Transition state and basically duplicate what AnimatedContent does so I can apply the correct animation in the AnimatedVisibilityScope.

Consider creating your own Transition, and using Transition.AnimatedContent instead. That way you could read the initial/target state from Transition in the AnimatedVisibilityScope : https://developer.android.com/reference/kotlin/androidx/compose/animation/package-summary#(androidx.compose.animation[…].Alignment,kotlin.Function2)

AnimatedVisibilityScope is designed to host additional enter/exit animations from children. So this would be a work around until we add support for more types enter/exit on the ContentTransform level. 🙂 Thanks for the feature request
