title: how to enable or disable scrolling on FlatList
body: <p>I have a <code>FlatList</code> which is wrapped in a View.</p>
  
  <pre><code>&lt;View {...this._panResponder.panHandlers}&gt;
  &lt;FlatList .../&gt;
  &lt;/View&gt;
  </code></pre>
  
  <p>the View is a <code>panResponder</code>, so how to disable FlatList's scrolling when <code>onPanResponderGrant</code> triggers.</p>
