Just played with

AnimatedVisibility

. Really like how simple the API is and fits really well to a host of different use cases. Here is what I implemented to demonstrate list deletion with animation. Thanks for your work on this @Doris Liu 👏🏼 Here is the code with comments if anyone is interested - https://github.com/vinaygaba/Learn-Jetpack-Compose-By-Example/blob/master/app/src/main/java/com/example/jetpackcompose/animation/ListAnimationActivity.kt#L53

I was going to try

AnimatedVisibility

to hide TopAppBar when content was scrolled but

LazyColumnFor

still doesn't share its scroll state. Maybe there is another way to achieve the same affect?

Yes, scroll delta seems to be a part of the internal state at the moment. Perhaps it's worth filing a feature request to expose some of the scroll info?

Does it support different interoplators?

Yes, you could specify different interpolations via `AnimationSpec`s for fade/expand/shrink/slide

What is the ExperimentalAnimationApi annotation added to composables?

It’s just for code health sake. Similar to the

@Deprecated

annotation, this annotation just notifies the user that it’s still an experimental API and will continue to evolve/change. It’s mostly for expectation setting.

Very nice these

AnimatedVisibility

capabilities!
