title: How to schedule background tasks in Flutter?
body: <p>I have been looking a lot for this but haven't found any packages or a way to schedule background tasks in Flutter. Like in Android there is <code>WorkManager</code>,<code>AlarmManager</code>.</p>
  
  <p>I know I can access those classes using <code>MethodChannel</code>, but I want something that works for iOS and Android both. </p>
  
  <p>(Its very disappointing that a mobile framework doesn't have the ability to schedule background tasks).</p>
