I need to animate item additions/removals in a `LazyColumn`, which is currently not a built-in functionality (issue: <https://issuetracker.google.com/issues/150812265>). How are other people solving this? No animation is quite jarring and waiting a few months for an official implementation doesn't really work.

I achieved this using `MutableTransitionState` and `AnimatedVisibility` . When a user deleted an item from the list, I changed the value of my MTS from true to false and had a `snapShotFlow` in a launchedEffect listen for when I should call remove (After the animation of animatedVisibility finished). A lot of our old built in 'free' functionality isn't added yet but all the tools to create it are.

we have a simple demo illustrating the idea - <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/animation/animation/integration-tests/animation-demos/src/main/java/androidx/compose/animation/demos/AnimatedVisiblilityLazyColumnDemo.kt|https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]/compose/animation/demos/AnimatedVisiblilityLazyColumnDemo.kt>
