Description

We have been facing an weird issue with FCM lately, where out users are still getting the notification even if they logout of the app. We are using Flutter for out android application, and a backend service that subscribes the FCM token to specific topics. Now when the user logs out of our application we delete the existing FCM token of the device using following method : await FirebaseMessaging.instance.deleteToken(); And after the token is deleted we get new token from the firebase method using final String? fcmToken = await FirebaseMessaging.instance.getToken(); what we have noticed is that the fcmToken which is different from the older token, but is still subscribed to the topic to which older token was subscribed. It should give a fresh token right which is not subscribed to any topic, right?, or is this an expected behaviour and we need to do some manual un-subscription from our end to avoid this issue? Please help!!

Reproducing the issue

static Future<void> forceRefreshFCMToken() async {
    final SharedPreferenceHelper prefHelper =
        GetIt.I.get<SharedPreferenceHelper>();
    final UserRepository userRepository = GetIt.I.get<UserRepository>();
    final DeviceRegisterInfo oldDeviceRegisterInfo =
        DeviceRegisterInfo.fromJson(await prefHelper.getRegisteredDeviceInfo());
    await FirebaseMessaging.instance.deleteToken();
    final String? fcmToken = await FirebaseMessaging.instance.getToken();
    if (fcmToken != null) {
      await prefHelper.updateDeviceInfo(
        deviceInfo: DeviceRegisterInfo(
          deviceId: oldDeviceRegisterInfo.deviceId,
          fcmToken: fcmToken,
        ).toJson(),
      );
      final DeviceRegisterInfo newDeviceRegisterInfo =
          DeviceRegisterInfo.fromJson(
              await prefHelper.getRegisteredDeviceInfo());
      UpsertDeviceResponse? upsertResponse;
      final Map<String, dynamic> deviceInfo = await getDeviceInfo();
      try {
        upsertResponse = await userRepository.upsertDevice(
          upsertDeviceRequest: UpsertDeviceRequest(
            deviceId: newDeviceRegisterInfo.deviceId,
            fcmToken: newDeviceRegisterInfo.fcmToken,
            deviceInfo: deviceInfo,
          ),
        );
      } catch (error, stack) {
        FirebaseCrashlytics.instance.recordError(error, stack);
      }

      if (upsertResponse != null) {
        await prefHelper.updateDeviceInfo(
          deviceInfo: newDeviceRegisterInfo
              .copyWith(
                userMapped: upsertResponse.userMapped,
                deviceSynced: true,
              )
              .toJson(),
        );
      }
    }
  }

This the code, if you see lines

await FirebaseMessaging.instance.deleteToken();
final String? fcmToken = await FirebaseMessaging.instance.getToken();

We delete the existing token with deleteToken() method and get new token in the next line.

The new token which we have got, is already subscribed to all the topics, while we still haven't made any calls to our BE service for the subscription.
