title: React Native, ScrollView Paging event
body: <p>I'm using a Horizontal ScrollVIew with paging in react native, I'm trying to recreate the coverflow view like Spotify. visually is perfect however I want to call a function when paging left or right, like playNext or playPrev. is there a way to listen to the paging event and direction?</p>
  
  <pre><code>&lt;ScrollView pagingEnabled={true} horizontal={true}&gt;
  
      &lt;CoverFlowItem page_width={D.width} width={width} height={height}
                             source={{uri: current.poster}}/&gt;
   .....
  
  
   &lt;/ScrollView&gt;
  </code></pre>
