title: Android: Handler.post() equivalent in Flutter
body: <p>In Android, we have <code>Handler.post()</code> method which can run after every fixed time interval like this. </p>
  
  <pre><code>Handler handler = new Handler();
  
  handler.post(new Runnable() {
    public void run() {
    // ... this runs after every second 
    handler.postDelayed(this, 1000); // makes run() run after every 1000 ms
    }
  }
  </code></pre>
  
  <p>Do we have anything similar in Dart or Flutter?</p>
  
  <p>PS: The similar of <code>Handler.postDelayed()</code> is <code>Future.delayed()</code>. I am asking for <code>Handler.post()</code></p>
