Support Animated.ScrollView with Animated.event() (#264)
Support Animated.ScrollView with Animated.event() (#264)

Hi,

Current implementation does not support passing a onScroll listener using `Animated.event()` listener, which is particularly useful when you want to implement a ScrollView with native driver parallax effects or things like that.

I just discovered there's this "Animated.forkEvent" method which permit to add a listener to the existing user onScroll callback. It works with both original function and Animated.event(): https://github.com/facebook/react-native/blob/c6b96c0df789717d53ec520ad28ba0ae00db6ec2/Libraries/Animated/src/AnimatedImplementation.js#L477
