title: Flutter - shift focus to specific widget
body: <p>I am developing a flutter app targeting visually impaired users. In my app after the user search for information using editbox. The app lack notifying the user that the search completed. </p>
  
  <p>I am willing to do that by shifting focus to search result so that the screen reader reads it (Talkback or VoiceOver). In Android for example I can use :</p>
  
  <pre><code>View.requestFocus();
  </code></pre>
  
  <p>I am looking for approach to perform the same thing in flutter or custom platform code</p>
