Scroll to top of ScrollView

in functional components

import { useRef } from 'react';

const scrollRef = useRef();

const onPressTouch = () => {
  scrollRef.current?.scrollTo({
    y: 0,
    animated: true,
  });
}

<ScrollView ref={scrollRef}>
  ...your elements
</ScrollView>

<TouchableOpacity onPress={onPressTouch}></TouchableOpacity>

1. First add a ref attribute to your ScrollView component. Example: <ScrollView ref='_scrollView'>
2. Then wherever you want to scroll to top do this Example: onPress={() => { this.refs._scrollView.scrollTo(0); }}
