title: Android onResume() method equivalent in Flutter
body: <p>I am working on a Flutter app and need to pop the screen. I tried <code>initState()</code> method but no luck. <code>initState()</code> gets called when I open a class for the first time.</p>
  
  <p>Do we have an equivalent of Android <code>onResume()</code> method in Flutter?</p>
  
  <p>Any ideas?</p>
