title: How to add add new packages in expo snack?
body: <p>I want to use <strong>expo-av</strong> package in expo snack. However I know that after importing <strong>expo-av</strong> at App.js file. I have to add the <strong>expo-av</strong> at <code>package.json</code> file.</p>

  <p>But I want to use packages like this one, in the <code>App.js</code> file without manually typing the version on <code>package.json</code> file.</p>
  <h2>Is there any way to add packages in expo snack automatically after import? If I am missing this feature please let me know.</h2>
