Pass parameter

[AliEasy]

I need to pass Parameter(Not a token but sth like an Id) with HubConnection before _hubConnection.start()
Any help?!

Could you provide more information, code sample, documentation for supported SignalR clients demonstrating the desired result?

Below is my code on Flutter:

    final connection = HubConnectionBuilder()
        .withUrl(
            'http://xxxxxx.net/',
            HttpConnectionOptions(
              transport: HttpTransportType.webSockets,
              logging: (level, message) => print(message),
            ))
        .withAutomaticReconnect()
        .build();

    await connection.start();

    connection.on("RecieveNotification", (message) {
      print(message.toString());
    });

    await connection.invoke("SendNotifications");

Also I need to send a parameter like userId

Im doing the same thing on Java and it works correctly
The code is like this:

            Platform.loadPlatformComponent(new AndroidPlatformComponent());
            Credentials credentials = new Credentials() {
                @Override
                public void prepareRequest(Request request) {
                    request.addHeader("userId", 3 + "");
                }
            };
            String serverUrl = "http://xxxxxx/";
            mHubConnection = new HubConnection(serverUrl);
            mHubConnection.setCredentials(credentials);
            String SERVER_HUB_CHAT = "notificationHub";
            mHubProxy = mHubConnection.createHubProxy(SERVER_HUB_CHAT);
            ClientTransport clientTransport = new ServerSentEventsTransport(mHubConnection.getLogger());
            SignalRFuture<Void> signalRFuture = mHubConnection.start(clientTransport);
