        path: 'assets/translations',

        child: const BlocManager()));
}

_ablyMessagingBackgroundHandler also not called

pubspec.yaml firebase_core: ^2.12.0 firebase_messaging: ^14.6.0 firebase_analytics: ^10.4.0 firebase_crashlytics: ^3.3.0 flutter_local_notifications: ^17.2.1 device_info_plus: ^10.0.1 ably_flutter: ^1.2.34

Hey @tharro,

Thank you very much for reporting this issue! Could you please let us know on which platform this issue occurs—Android, iOS, or both? Additionally, could you share a verbose log from your app? Lastly, does the problem occur immediately after installing ably_flutter, even if ably.Push.notificationEvents.setOnBackgroundMessage(_ablyMessagingBackgroundHandler); hasn’t been called?

Yep, both. The problem occur immediately after installing ably_flutter event if ably.Push.notificationEvents.setOnBackgroundMessage(_ablyMessagingBackgroundHandler); hasn’t been called. I will show verbose log soon

When I remove 'ably_flutter'. _firebaseMessagingBackgroundHandler is working. If re-install 'ably_flutter', it's not working.
