signalr error with negotiation request with https protocol and not accepting json response callbacks - signalr_flutter

[IbrahimSulai]

Hi Team,

I am using the component: signalr_flutter Version 0.2.1,
but i am unable to connect to Server with https protocol, not even getting proper error response. from plugin.
and not able to getting callbacks response in JSON format. In hubCallbacks methods.
I cannot find a way How to fix this. can we customized http client in SignalR plugin. and plugin must support hubCallback with JSON model not only String.
signalR = SignalR(
'https://server-name/', "HUB-NAME",
hubMethods: ["methods1", "Methods2"],
statusChangeCallback: (status) => {
if (status == ConnectionStatus.connected)
{
print("Connected to SignalR Hub"),
signalR.invokeMethod("subscribeForNotifications", arguments: [
arg1
arg2,
]).then((result) {
print("Subscribed for notifications: $result");
}).catchError((err) {
print("Error subscribing for notifications: $err");
})
}
},
hubCallback: (methodName, message) =>. // message only as String other format not supported.
{
print('MethodName = $methodName, Message = $message')
}
);
await signalR.connect();

Please let me know if any issues / clarifications is required on the same.

Thanks and Regards,
Ibrahim Sulaiman

Hi, some user made a fork of this repo with some modifications to get the response no matter the format, i forked it again and tried to fix some problems that i faced, you can try it out here: https://github.com/SmearyQuill/signalr_flutter.git

just override the pubspec.yaml to use that repo instead of the original one

i get the response like this:
var newMsg = NewIncomingMessage.fromJson(jsonEncode(data));

here data is a string with the response, i encode it again so then i can decode using a factory, you would need to do some manual conversions probably to fit your needs

also if you are using iOS my repo currently throws an exception when a message is received, i guess i need to fix that but feel free to suggest any changes if you know how to fix it
