the answer can't get streams from the caller !!

[Basim2Shaban]

i am facing this issue when i am trying to make call between two users
the caller user can get the streams very well but the answer user cannot get any streams !!
this is my code ...

@override
 void initState() {
   super.initState();
   _localRenderer.initialize();
   _remoteRenderer.initialize();
   SocketConnections.makeCall(caller_data);

   WidgetsBinding.instance.addPostFrameCallback((timeStamp)async{
     SocketConnections.sio!.on(caller_data['caller_id'].toString()+caller_data['receiver_id'].toString(), (data){
       final mediaStream =
       navigator.mediaDevices.getUserMedia({"video": true, "audio": false});
       mediaStream.then((value) => {
         setState(() {
           _localRenderer.srcObject = value;
             debugPrint("Con id : ${peer.open}");
             callConnection = peer.call(caller_data['receiver_id'].toString(),value);
           peer.on<MediaConnection>("call").listen((call) async {
             mediaConn = call ;
             debugPrint("into the call");
             final mediaStream = await navigator.mediaDevices
                 .getUserMedia({"video": true, "audio": true});
             mediaConn.answer(mediaStream);
             mediaConn.on<MediaStream>("stream").listen((event) {
               debugPrint("start streaming");
               _localRenderer.srcObject = mediaStream;
               print(event.getVideoTracks().length);
               _remoteRenderer.srcObject = event;
               setState(() {
                 // CallProvider.answer = true;
               });
             });
             mediaConn.on("close").listen((event) {
               // callProvider.onCancelCall();
             });
           });
             callConnection.on("close").listen((event) {
               // callProvider.onCancelCall();
             });
         })
       });
     });
     var myID = await AppHelper.getUserId();
     peer = Peer(id:myID,options: PeerOptions(host:'192.168.43.197' ,secure: false,port: 9000));
     print("${peer.id!}======== this is peer");
     peer.connect(caller_data['receiver_id'].toString());

   });

 }

and here is the answer widget

  @override
  void initState() {
    super.initState();
    _localRenderer.initialize();
    _remoteRenderer.initialize();
    peer = Peer(id:myID,options: PeerOptions(host:'192.168.43.197' ,secure: false,port: 9000));

    WidgetsBinding.instance.addPostFrameCallback((timeStamp)async{
      // if(!CallProvider.answer){
      //   return ;
      // }
      var myID = await AppHelper.getUserId();
      // peer = Peer(id:myID,options: PeerOptions(host:'192.168.43.197' ,secure: false,port: 9000));
      print("${peer.id!}======== this is peer");
      peer.connect(callerData['caller_id'].toString());
      final mediaStream =
      navigator.mediaDevices.getUserMedia({"video": true, "audio": false});
      mediaStream.then((value) => {
        setState(() {
          _localRenderer.srcObject = value;
          peer.on<MediaConnection>("call").listen((call) async {
            mediaConn = call ;
            CallProvider.inCall = true;
            debugPrint("into the call");
            final mediaStream = await navigator.mediaDevices
                .getUserMedia({"video": true, "audio": true});
            mediaConn.answer(mediaStream);
            mediaConn.on<MediaStream>("stream").listen((event) {
              debugPrint("start streaming");
              setState(() {
                _localRenderer.srcObject = mediaStream;
                print(event.getVideoTracks().length);
                _remoteRenderer.srcObject = event;
                // CallProvider.answer = true;
              });
            });
            mediaConn.on("close").listen((event) {
              // callProvider.onCancelCall();
            });
          });
        })
      });
    });


  }

Hey @Basim2Shaban.
You opened this in the server repository. Does your code work when using the public server?

In any case, this is too much code to check by hand and not enough to run it. Maybe you can provide a minimal repository?
