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 :)
