title: App Layout with AngularDart does not show Item on Drawer
body: <p>I am trying reproduce the following App Layout Demo (app_layout_demo) example:</p>
  
  <p><a href="https://github.com/dart-lang/angular_components_example/tree/master/lib/src/app_layout_demo" rel="nofollow noreferrer">https://github.com/dart-lang/angular_components_example/tree/master/lib/src/app_layout_demo</a></p>
  
  <p>There are these items that should appear in the drawer:</p>
  
  <pre><code>&lt;material-drawer persistent #drawer="drawer" [attr.end]="end ? '' : null"&gt;
    &lt;material-list *deferredContent&gt;
      &lt;div group class="mat-drawer-spacer"&gt;&lt;/div&gt;
      &lt;div group&gt;
        &lt;material-list-item&gt;
          &lt;material-icon icon="inbox"&gt;&lt;/material-icon&gt;Inbox
        &lt;/material-list-item&gt;
        &lt;material-list-item&gt;
          &lt;material-icon icon="star"&gt;&lt;/material-icon&gt;Star
        &lt;/material-list-item&gt;
        &lt;material-list-item&gt;
          &lt;material-icon icon="send"&gt;&lt;/material-icon&gt;Sent Mail
        &lt;/material-list-item&gt;
        &lt;material-list-item&gt;
          &lt;material-icon icon="drafts"&gt;&lt;/material-icon&gt;Drafts
        &lt;/material-list-item&gt;
      &lt;/div&gt;
      &lt;div group&gt;
        &lt;div label&gt;Tags&lt;/div&gt;
        &lt;material-list-item&gt;
          &lt;material-icon icon="star"&gt;&lt;/material-icon&gt;Favorites
        &lt;/material-list-item&gt;
      &lt;/div&gt;
    &lt;/material-list&gt;
  &lt;/material-drawer&gt;
  </code></pre>
  
  <p>But it does not show Item on Drawer. See:</p>

  <p>There is also an error in the browser console: </p>
  
  <pre><code>EXCEPTION: Invalid argument(s): No provider found for DomService. html_dart2js.dart:3559
  </code></pre>
  
  <p>What could be the problem?</p>
