title: Problem with Getting object from class of back4app database FLUTTER ONLY
body: <p>I'm getting dumb with this</p>
  <pre><code>Future Object1() async{
  final object1 = await ParseObject('Announcement')..objectId='vG1WZeVHkV';
  var mal = await object1.get('an1');
  await print(mal);
  </code></pre>
  <p>}</p>
  <p>just in case you ask the result for that</p>
  <pre><code>I/flutter ( 9123): null
  </code></pre>
  <p>when I was hoping for this url (it is a file column in back4app for image)</p>
  <pre><code>&quot;an1&quot;:{&quot;__type&quot;:&quot;File&quot;,&quot;name&quot;:&quot;6c128c064142552b8c3a5e2ac016bc1d_1.jpg&quot;,&quot;url&quot;:&quot;https://parsefiles.back4app.com/nQ1FGO9uklC7f9eMKYDuA16pvAjamCYnbI6xD2Zy/6c128c064142552b8c3a5e2ac016bc1d_1.jpg&quot;}
  </code></pre>
  <p>(note I got this from using object1.fetch() )</p>
  <p>so can anyone help me???</p>
