Get current scroll position of ScrollView in React Native

Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native?

So something like:

<ScrollView
  horizontal={true}
  pagingEnabled={true}
  onScrollAnimationEnd={() => { 
      // get this scrollview's current page or x/y scroll position
  }}>
  this.state.data.map(function(e, i) { 
      <ImageCt key={i}></ImageCt> 
  })
</ScrollView>

Try.

<ScrollView onScroll={this.handleScroll} />

And then:

handleScroll: function(event: Object) {
 console.log(event.nativeEvent.contentOffset.y);
},

In another context, let's say you also want to implement a pagination indicator, you'll want to go further by doing this:

<ScrollView
     onScroll={Animated.event([{ nativeEvent: { contentOffset: { x: 
     scrollX } } }], {listener: (event) => handleScroll(event)})}
     scrollEventThrottle={16}
>
   ...some content
</ScrollView>

where scrollX would be an animated value you can use for you pagination and your handleScroll function can take the form:

  const handleScroll = (event) => {
    const positionX = event.nativeEvent.contentOffset.x;
    const positionY = event.nativeEvent.contentOffset.y;
  };
