title: Flutter push notifications offline on backgroud
body: <p>I am trying to make a new todo tasks app and its offline no intternet needed...</p>
  <p>I want to get reminded when the tasks time is up</p>
  <p>i tried using local notification it worked as showing notification but for my phone as the README section of the package said that it doesnt work for everybody's phone for such android things... So when i terminate my app or having it on my backgroud and wait for the schedule notification nothing appear...</p>
  <p>So any idea of how i can let my app work on backgroud</p>
