callKeep.setup throws type 'Null' is not a subtype of type 'List<String>' in type cast

cdg720 commented 3 years ago

Hi,

When I call await callKeep.setup(null, callSetup); I get the following error messages

I/flutter ( 9569): FlutterFire Messaging: An error occurred in your background messaging handler:
I/flutter ( 9569): type 'Null' is not a subtype of type 'List<String>' in type cast

Longer code, which basically I copied from the example:

Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
  final callKeep = FlutterCallkeep();
  final callSetup = <String, dynamic>{
    'ios': {
      'appName': 'CallKeepDemo',
    },
    'android': {
      'alertTitle': 'Permissions required',
      'alertDescription':
      'This application needs to access your phone accounts',
      'cancelButton': 'Cancel',
      'okButton': 'ok',
      // Required to get audio in background when using Android 11
      'foregroundService': {
        'channelId': 'com.company.my',
        'channelName': 'Foreground service for my app',
        'notificationTitle': 'My app is running on background',
        // 'notificationIcon': 'Path to the resource icon of the notification',
      },
    },
  };
  await callKeep.setup(null, callSetup);
}

Does anyone know what is causing this problem?

In my pubspec.yaml, I have:

callkeep: ^0.3.1
firebase_messaging: ^10.0.4

setup expects 'additionalPermissions': <String>[] and now I am getting the following errors:

E/flutter (13208): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: PlatformException(E_ACTIVITY_DOES_NOT_EXIST, Activity doesn't exist, null, null)

It seems like I am missing actual additionalPermissions but I am not sure which ones.

I will close this since the title error went away even though setup still doesn't work for me.
