NullPointerException when restarting the foreground service with a null intent #2298

I'm getting a Fatal Exception: java.lang.RuntimeException: Unable to start service com.dexterous.flutterlocalnotifications.ForegroundService@d50aeda with null: java.lang.NullPointerException: Attempt to invoke virtual method 'java.io.Serializable android.content.Intent.getSerializableExtra(java.lang.String, java.lang.Class)' on a null object reference

t seems to happen when the app is in the background and the user taps on the foregroundservice notification. I'm not able to reproduce it myself, caught by Crashlytics.

Using the default: 'START_STICKY', I would just need the tap on the foreground to open the app.

Current implementation:

Future<void> _startForegroundService(
  FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin,
  int id,
  String title,
  String body,
  AndroidNotificationDetails details,
) async {
  try {
    await flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()
        ?.startForegroundService(
          id,
          title,
          body,
          notificationDetails: details,
          // startType:
        );
  } catch (e) {
    print('Error starting foreground service: $e');
  }
}
 @pragma('vm:entry-point')
  static void notificationTapBackground(
      NotificationResponse notificationResponse) {
    // Handle background notification tap here

    print(
        'Notification tapped in background: ${notificationResponse.actionId}');
  }

What am I missing here?

Line 25 in 5e7d4ee

intent.getSerializableExtra(ForegroundServiceStartParameter.EXTRA);

Should the null intent case be handled here? Or, would changing the foreground service start type to 'startRedeliverIntent' help me out?

I did not. Stopped using this feature, it was too unstable in my case.

Any update with this?
