Box values are empty even after insertion

[bilalgodesto]

Steps to Reproduce I am using firebase notification to get data. When data is received in background notification. I am adding to hiveBox Insertion is done successfully but when i tried to check the values i am getting empty box. Code sample

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  print('_firebaseMessagingBackgroundHandler CALLED');
  await Firebase.initializeApp();

  try {
   
    await Hive.initFlutter();
    Hive.registerAdapter(ConnectionsAdapter(), override: true);
    if (!Hive.isBoxOpen('connection_box')) {
      await Hive.openBox<Connections>('connection_box');
    }

 if (message.data['messageType'] == 'connection_request') {
       final connection = Connections()
      ..id = DateTime.now().microsecond.toInt()
      ..connectionState = 'Pending'
      ..userName = event.data['userName'];

    final box = Boxes.getConnections();
    await box.put('${event.data['senderId']}', connection);
    print('BOX in INSERTED PERFECTLY');
    }

  } catch (e) {
    print('${e.toString()} Exception');
  }


And then in widget

 ValueListenableBuilder(
          valueListenable: Boxes.getConnections().listenable(),
          builder: (BuildContext context, Box<Connections> box, _) {
            final connection = box.values.toList();
            print(box.values);
            print('BOX VALUES');
},);
