title: Flutter- drag down to dismiss
body: <p>I'd like to dismiss page with drag down like this.
  But I don't know whether use <code>gesture</code> or <code>draggable</code> either way I have no idea how to show previous page as you drag down.
  Anyone know how to do?</p>

  <p><strong>Edit</strong></p>
  
  <p>I ended it up like this.<br>
  I'm not sure if this is the best way but at least it works fine for me.<br>
  Hope it helps someone:)</p>
  
  <pre><code>return Dismissible(
    key: Key('some key here'),
    direction: DismissDirection.down,
    onDismissed: (_) =&gt; Navigator.pop(context),
    child: Scaffold(
      body: Center(
        child: Image.network(
          'URL',
          fit:BoxFit.cover
        ),
      ),
    ),
  );
  </code></pre>
