same issue here, my guy, how far now, abeg do fix this issue, thanks jare

[peterson-umoke]

in fact na only the public channels dey work, this thing get as e be oh, wetin be the problem ?

[heywhy]

I want to assume you set the auth field on the PusherOption, right?

[peterson-umoke]

Let me share the codebase

[heywhy]

A snippet of the pusher initialization block is enough.

[peterson-umoke]

I have made some changes and i now receiving yet another different error. here is my codebase.

String _authUrl = "http://$url:$port/broadcasting/auth";
      Map headers = await _headers;

      log("the authrlksdlfsdf ${headers['Authorization']}");

      PusherAuth _pusherAuth = PusherAuth(
        _authUrl,
        headers: headers,
      );
      log("${_pusherAuth.toJson()}");

      PusherOptions _pusherOptions = PusherOptions(
        host: url,
        port: port,
        encrypted: false,
        auth: _pusherAuth,
      );

      _pusher = FlutterPusher(
        appKey,
        _pusherOptions,
        lazyConnect: true,
        enableLogging: true,
        onConnectionStateChange: (ConnectionStateChange events) =>
            log("${events.currentState}"),
        onError: (ConnectionError e) =>
            log("Error occurred logging you in with auth tokens ${e.toJson()}"),
      );

      _pusher.connect();
      _echo = new Echo({
        "broadcaster": "pusher",
        "client": _pusher,
      });

      try {
//        _echo
//            .channel('heartbeat')
//            .listen('Heartbeat', (e) => log("Public channel result: $e"));
        _echo
            .private('heartbeat')
            .listen('Heartbeat', (e) => log("Private channel result: $e"));
      } on PlatformException catch (e) {
        print("Error occurred trying to login with your key, $e");
      }

event though i have updated this, i keep getting error that the headers are not been set

[heywhy]

I'll like you to create an issue at flutter_pusher_client. This issue is not related to this library.
