React Native is awesome, and it's a know issue :)

The animations in the apps out there are awesome as well. The natives (iOS and Android) let u many animation with super easy API, and React Native does the same, Animated API is awesome (and LayoutAnimation).

But, What about some scrollview animation? Animate while scroll a listview which depend on the scroll position. The "onScroll" function isn't good enough for animaition and leads to a flacky scrolling.

For example, Apple's messages app with the nice bounce listview (or in iOS terms UITableView). Can't we ever achieve something like that?

See an example here:

I aware of the bridge limitation, but hey! Let's try to do some magic, as u already did with React Native :)
