In web_socket_channel connection can't set header for authentication

[anjojy]

can't pass authentication cookie when create `channel

final _channel = WebSocketChannel.connect(Uri.parse('URL'));

As stated in this answer, apparently the use of authorization HTTP headers is not the intended way to perform authentication in the web socket protocol. Suggested alternatives are:

• send the token in a query parameter of the web socket URL
• send the token as the first message, after connection is etablished
• send the token in the web socket protocol header (seems like a hack to me, but it works)

Use IOWebSocketChannel instead of WebSocketChannel.connect

_channel = IOWebSocketChannel.connect(
        Uri.parse(Constants.connectionUrl),
        headers: Headers.getHeaderParameters(),
      );
