🐛 [firebase_messaging] Error receiving background notifications for "Android 12" just when permissions are checked #10359
Description
Bug report
Describe the bug
I am a bit desperate with an error when receiving push notifications in the background,; Error receiving background notifications in "Android 12" device, just when permissions are checked
I was looking for possible solutions but I haven't found anything that worked, can you help me, maybe it's a bug in the firebase_messaging library? Has anyone experienced something similar?
Steps to reproduce
A notification is sent and the app is in background
Devices & versions:
- [FAIL] Physical Devide with Android 12: Fail
- [✓] Physical Devide with Android 13: run perfect
- [✓] Physical Devide with IOs 16.2: run perfect
NOTE: I'm not sure if other versions prior to 12 get this error
Flutter code where the error occurs:
I have tried both possibilities with the same result:
NotificationSettings settings = await FirebaseMessaging.instance.requestPermission();
OR
NotificationSettings settings = await FirebaseMessaging.instance.getNotificationSettings();
Flutter Error:
I/flutter (11341): FlutterFire Messaging: An error occurred in your background messaging handler:
I/flutter (11341): [firebase_messaging/unknown] Attempt to invoke virtual method 'java.lang.Object android.content.Context.getSystemService(java.lang.String)' on a null object reference
