title: How do I check when the user has stopped scrolling?
body: <p>I am using <a href="https://facebook.github.io/react-native/docs/scrollview.html" rel="nofollow">https://facebook.github.io/react-native/docs/scrollview.html</a>, which has a handy <code>onScroll</code> prop, but how do I get when the user has stopped scrolling?</p>
  
  <p>Basically, I'd like to hide a button when the user is scrolling, show it when they aren't. </p>
