I also need this – enter/exit animations, height mostly. I've attempted it a few times, lost half an hour, and gave up and gone back to <Animated.FlatList /> with itemLayoutAnimation.

Basic use case: list of items with iOS swipe actions, where deleting an item (removal from list) should involve some sort of transition/animation, and same for population of new items.
