  <p>How would you center the extended FAB provided in Flutter like the Material design spec?</p>
  
  <p>Here the extended FAB is right aligned:</p>
  
  <pre><code>new Scaffold(
      floatingActionButton: new FloatingActionButton.extended(
          onTap: () =&gt; {},
          label: new Text('See all results')
      }
  )
  </code></pre>
