Flutter align button to bottom of Drawer : <p>I'm trying to have a Widget align to the bottom of my NavDrawer while still keeping a DrawerHeader and a list at the top of the Drawer. Here's what I'm trying:</p>

<pre><code>drawer: new Drawer(
    child: new Column(
      mainAxisSize: MainAxisSize.max,
      children: &lt;Widget&gt;[
        new Text('Top'),
        new Align(
          alignment: FractionalOffset.bottomCenter,
          child: new Text('Bottom'),
        ),
      ],
    ),
  ),
</code></pre>

<p>The bottom text should be aligned to the bottom of the drawer, but It isn't!</p>
