title: How to scroll to bottom of React Native ListView
body: <p>I'm writing an app using React Native. It has a <code>ListView</code> to show the list of items.</p>
  
  <p>I'm appending new items at the bottom when there are new ones available.
  I'd like to scroll to bottom in the <code>ListView</code> to show the new items automatically. How can I do this?</p>
