title: Is it possible to have transparent overlays from another route?
body: <p>So, I have the following code which allows me to push a semi-transparent overlay.</p>
  
  <pre><code>Navigator.of(context).push(PageRouteBuilder(
      opaque: false,
      pageBuilder: (BuildContext context, _, __) =&gt;
          LoadingScreen()));
  </code></pre>
  
  <p>Now I would like for me to do this as a named route so that I can retrieve the current route name from <code>ModalRoute.of(context).settings.name</code>. So my question is how do I define this to accomplish my goal?</p>
