Flutter Keep Application Awake

Let’s learn how to keep the application in flutter. You may install a plugin called

wakelock

This plugin keeps your the mobile screen awake as long as your application runs.

You can do like below

Wakelock.enable() // to start enabling awaking the screen
Wakelock.disable() // to turn off the wake lock. It means OS will shut down //the screen when necessary.

Here is an example how to use it in an app code.

class WorkoutCubit extends Cubit<WorkoutState>{
  WorkoutCubit():super(const WorkoutInitial());

  Timer? _timer;
  onTick(Timer timer){
    if(state is WorkoutInProgress){
      WorkoutInProgress wip = state as WorkoutInProgress;
      if(wip.elapsed!< 110){
        emit(WorkoutInProgress( wip.elapsed!+1));
    
      }else{
        _timer!.cancel();
        Wakelock.disable();
        emit(const WorkoutInitial());
      }
    }
  }

  startWorkout( [int? index]){
    Wakelock.enable();
    if(index != null){
      emit(const WorkoutInProgress( 0));
    }else{
      emit(const WorkoutInProgress( 0));
    }
    _timer = Timer.periodic(const Duration(seconds: 1), onTick);
  }

}

See how we used Wakelock.enable() to start out timer app.

We disable it using Wakelock.disable() when our timer counts down to the time.
