        itemCount: movies.length,
        key: GlobalKey(debugLabel: "gridView"),
  </code></pre>
  
  <p>I can not access my GridView while testing by calling</p>
  
  <pre class="lang-dart prettyprint-override"><code>find.byKey(Key('gridView'));
  </code></pre>
  
  <p>nether </p>
  
  <pre class="lang-dart prettyprint-override"><code>find.byKey(GlobalKey(debugLabel: "gridView"));
