title: Why cant I find my drawer? It literally pops open when swiping
body: <p>My drawer opens perfectly fine when swiping so I know that there is one there. However the below says different:</p>
  <pre><code>print('Has drawer');
  print(Scaffold.of(context).hasDrawer);
  print('ancestor scaffold');
  print(Scaffold.maybeOf(context)?.hasDrawer);
  </code></pre>
  <p>Result:</p>
  <pre><code>Has drawer
  false
  ancestor scaffold
  false
  </code></pre>
  <p>Where can it be? How can I access it via a button instead of swiping?</p>
