signalr error during negotiation request - signalr_flutter

[smithFlutter]

Hello everyone,

I am using the component: signalr_flutter, but when connecting to the server it gives me the error: "signalr error during negotiation request", I have seen that there is a way to skip the negotiation but I cannot find a way with this component, has this happened to anyone?.

Code:
`Future initPlatformState() async {
signalR = SignalR(
"http://midireccion",
"mipuerto",
hubMethods: ["sendPushClient"],
statusChangeCallback: _onStatusChange,
transport: Transport.longPolling,
hubCallback: _onNewMessage,
);
}

void connectedServer() async
{
await signalr.connect(); //here error....
}

`

Thanks for the help :)

Veo que usaste "mipuerto" así que me tomaré la libertad de asumir que hablas español, tu servidor ocupa algún tipo de autenticación? quizas necesitas agregar el token adecuado para que el servidor acepte la comunicación, yo recibía el mismo error por esta razón, probablemente lo puedes enviar utilizando los parametros "queryString" o "headers", yo lo hago así:

`String get getJWT => "access_token=$_token";

Future initConnection() async {
if(_signalRNotificationsHub != null && (await _signalRNotificationsHub!.isConnected())) return;
if (_token.isEmpty) return;
_signalRNotificationsHub = SignalR(
'http://localhost:6038',
notificationHubName,
queryString: getJWT , <--- aquí añado el token
hubMethods: getNotificationsHubServerMethods, // Methods from server
transport: Transport.serverSentEvents,
...
