To use Authorize

[cyberprophet]

If you want to use [Authorize], you can use IOWebSocketChannel instead of WebSocketChannel to pass Header.

_webSocket = IOWebSocketChannel.connect(Uri.parse(url), headers: {
      'Authorization':
          'Bearer ${_accessTokenFactory != null ? await _accessTokenFactory!() : ''}'
    });

It is also possible to transmit the entire header by slightly modifying the code in part lib/web_socket_transport.dart.
