[pedometer 4.0.1] stepCountStream listened in a Foreground Service does not trigger onData when phone is locked and screen is closed. Triggers when lock screen is shown again. #952
I'm developing a Flutter app using pedometer package to track steps of the user. I want to count steps when app is closed as well, so I used flutter_background_service package as well in order to use foreground service on Android.
Basically this is my setup Background Service initialization logic (which is basically configured to use onStart method mentioned below):
Future<void> initializeBackgroundService() async {
final service = FlutterBackgroundService();
await service.configure(
androidConfiguration: AndroidConfiguration(
// this will be executed when app is in foreground or background in separated isolate
onStart: onStart,
// auto start service
autoStart: true,
isForegroundMode: true,
notificationChannelId: 'my_foreground',
initialNotificationTitle: 'AWESOME SERVICE',
initialNotificationContent: 'Initializing',
foregroundServiceNotificationId: 888,
),
iosConfiguration: IosConfiguration(
// auto start service
autoStart: true,
// this will be executed when app is in foreground in separated isolate
onForeground: onStart,
// you have to enable background fetch capability on xcode project
onBackground: onIosBackground,
),
);
}
onStart method (method called when foreground service is started):
listen callback of stepCountStream is called in the following scenarios:
When app is open
When app is minimized
When app is closed
When phone lock screen is shown
And as you can see in the code, "STEP DATA LISTENED!!!" is printed on debug console.
But when phone is locked and screen goes black, this callback is not triggered even when user takes steps. When user uses lock button to show lock screen, it is triggered again. I want to be able to read step data even when phone is sleeping (locked and screen is black).
I wanted to see if this is a foreground service issue, that's why I added the following:
"TIMER: 2024-04-27 21:58:00.657213!!!" is printed every second even when phone is locked and screen goes black. So it's clearly not a foreground service issue.
Has anyone encountered a problem similar to this? Is there anything I can do to ensure listen callback is triggered even when phone is sleeping (locked and screen is black)?
