What is currently the best way to animate adding items to a column\lazy column?

with AnimatedVisibility component. we have a demo for something like this - https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]/compose/animation/demos/AnimatedVisiblilityLazyColumnDemo.kt

I thought animateItemPlacement does this ?

animateItemPlacement is animating item … placement 🙂 I mean its position when it changes. but not additions/removals

Cool, it looks like the secret souce is MutableTransitionState... I wonder why they haven't implemented internally in the API by now...
