title: How to push notification when your app is turn off, and without firebase?
body: <p>I am working on weather app project, I am using android-studio, and I would like to get a notification of the weather, even if, and especially when my application is turn off (1 notification per day, or 1 notification when you turn on your device).
  However, I don't use Firebase or any cloud, and I don't want.</p>
  
  <p>How can I do that with flutter ?</p>
  
  <p>I know about android_alarm_manager, but I don't know if it's the best way to do it. Or maybe, I should learn native iOS and android before to learn Futter ?</p>
  
  <p>Thanks for your help,</p>
