void main() async {
  /// Example 1
  /// One-off execution after 10 minutes (or more).
  ///
  /// If the app is stopped, and restarted again within 10 minutes, the scheduled time will be
  /// automatically retrieved and the function executed as scheduled.
  ///
  /// If the app is stopped, and restarted again after more than 10 minutes, `onMissedSchedule` will
  /// be executed immediately - which will in turn execute `onExecute`.

  /// Example 2
  /// Periodic execution every 10 minutes (or more).
  ///
  /// We're scheduling a new execution after 10 minutes every time the timer executes, which will
  /// create a "periodic" timer.

        // which will self-execute every 10 minutes.
