handshake failed with error 'Null check operator used on a null value' during start(). #40

When starting the connection i get the above error because await _handshakeCompleter!.future; _handshakeCompleter is null in _startInternal

No, i forked this repo and did a null check around the problematic code. Seems to work fine. https://github.com/daubit/signalr_client

Can you share that null check code ?

I added the check here: https://github.com/daubit/signalr_client/blob/master/lib/hub_connection.dart#L208
