Cannot start connection with server that requires authentication

[zuboje]

I have piece of code:

final hubConnection = HubConnectionBuilder() .withUrl( serverUrl, HttpConnectionOptions( accessTokenFactory: () => _secureStorage.read(key: 'bearerToken'), logging: (level, message) => print(message), )) .build();

await hubConnection.start();

My Hub connection variable always show that _accessTokenFactory is null, that function is never called. I tried creating separate function like:

Future getAccessToken() async{ var token = await _secureStorage.read(key: 'bearerToken'); return token; }

and calling it like this:

... accessTokenFactory: () => _getAccessToken(), ...

Putting debug point on "var token..." and it is never called, this function is never executed. Looking deeper into this, the only place that actually uses "accessTokenFactory" is "utils.dart" under "sendMessage" future. Problem is that connection cannot be established with the server without token. I have tested signalr server with simple client in .net and if I provide access token in hubconnection my server works and responds.

I have not had time to run your sample but I am looking at this:

accessTokenFactory() => _getAccessToken()

I would see if your only getting the Future because it is not async/await'd. Or you are getting it, but synchronously. Could you try that out and see if you get a better result?

The issue was on my end. My apology for the long delay I had to work on different areas of the app on my end to get back to this one. It was a server problem, not a plugin problem.
