When using Animated.createAnimatedComponent(ScrollView) to create an animated ScrollView it\'s not longer possible to use scrollTo.
Animated.createAnimatedComponent(ScrollView)
ScrollView
scrollTo
Try this to get the ref of the component returns from Animated.createAnimatedComponent method:
Animated.createAnimatedComponent
ref={(ref) => this.list = ref._component}
Then, calling this.list.scrollTo({x: 0, y: 0}) should work.
this.list.scrollTo({x: 0, y: 0})
