Recieve call for ios and android in Background ?

[harryandroiddev]

I was trying to enbale the firebase push notification in the flutter example app , after uncommenting the code there is an error occurs in the code can you please reivew and check why the issue is coming . below is the code .

@pragma('vm:entry-point')
Future _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

//!!! Method is working in the background isolate!
//!!! At this moment Activity may not exist or whole App could be completely stopped
//!!! Code below initializes Siprix, adds saved accounts and refreshes registration (makes app ready to receive incoming call)

debugPrint("[!!!] Handling a background message id:'${message.messageId}' data:'${message.data}'");

try{
debugPrint("Initialize siprix by push notif");
_MyAppState._initializeSiprix(); // here the error occurs it requires param to pass

debugPrint("Read and add accounts by push notif");
SharedPreferences prefs = await SharedPreferences.getInstance();
String accJsonStr = prefs.getString('accounts') ?? '';
if(accJsonStr.isNotEmpty) {
  AppAccountsModel tmpAccsModel = AppAccountsModel();
  await tmpAccsModel.loadFromJson(accJsonStr);
  tmpAccsModel.refreshRegistration();
}

} on Exception catch (err) {
debugPrint('Error: ${err.toString()}');
}
}

The method used is this requires context

static void _initializeSiprix(BuildContext context,
[LogsModel? logsModel]) async {
debugPrint('Initialize siprix');
InitData iniData = InitData();
iniData.license = "...license-credentials...";
iniData.logLevelFile = LogLevel.debug;
iniData.logLevelIde = LogLevel.info;

//- uncomment if required -//
//iniData.enableVUmeter = true;
//iniData.singleCallMode = false;
//iniData.tlsVerifyServer = false;
if (Platform.isIOS) {
  iniData.enableCallKit = true;
   iniData.enablePushKit = true; //Enable only when added PushNotif support on server side
  iniData.unregOnDestroy = false;
}
if (Platform.isAndroid) {
  iniData.unregOnDestroy = false;
  iniData.listenTelState = true;
  iniData.listenVolChange = true;
  iniData.serviceClassName = "com.siprix.voip_sdk_example.MyNotifService";
  iniData.singleCallMode = true;

  // context
  //     .read<DevicesModel>()
  //     .setForegroundMode(true)
  //     .catchError((e) {}); //set foreground servcie true by default
}
await SiprixVoipSdk().initialize(iniData, logsModel);

//Set video params (if required)
//VideoData vdoData = VideoData();
//vdoData.noCameraImgPath = await MyApp.writeAssetAndGetFilePath("noCamera.jpg");
//vdoData.bitrateKbps = 800;
//SiprixVoipSdk().setVideoParams(vdoData);

//Check the version
//String? version = await SiprixVoipSdk().version();
//debugPrint("Siprix version: $version");

}

It's not enough just uncomment code, you should also specify own Firebase credentials in main.dart:31.

You should proceed steps 1, 4 and 6 listed here:
