@abdalazeezalyosfi i have the same issue. have you had the solution for this?

If u need to send authorization token in headers (it works only with IOWebSocketChannel)- u may declare ur own transport (class implements ITransport), copy authors implementation, but replace block with injecting token in queryParams, then use ur own IOWebSocketChannel override method result like this:

@override
  Future<void> connect(String? url, TransferFormat transferFormat) async {
    assert(url != null);

    _logger?.finest('(WebSockets transport) Connecting');

    final websocketCompleter = Completer();
    var opened = false;
    url = url!.replaceFirst('http', 'ws');
    _logger?.finest("WebSocket try connecting to '$url'.");
    final token = await _accessTokenFactory?.call();
    _webSocket = IOWebSocketChannel.connect(
      Uri.parse(url),
      headers:
          token?.isEmpty ?? true ? null : {'Authorization': 'Bearer $token'},
    );
    opened = true;
    if (!websocketCompleter.isCompleted) websocketCompleter.complete();
    _logger?.info("WebSocket connected to '$url'.");
    _webSocketListenSub = _webSocket!.stream.listen(
      // onData
      (message) {
        if (_logMessageContent && message is String) {
          _logger?.finest(
            '(WebSockets transport) data received. message ${getDataDetail(message, _logMessageContent)}.',
          );
        } else {
          _logger?.finest('(WebSockets transport) data received.');
        }
        if (onReceive != null) {
          try {
            onReceive!(message);
          } catch (error) {
            _logger?.severe(
              '(WebSockets transport) error calling onReceive, error: $error',
            );
            _close();
          }
        }
      },

      // onError
      onError: (Object? error) {
        final e = error ?? 'Unknown websocket error';
        if (!websocketCompleter.isCompleted) {
          websocketCompleter.completeError(e);
        }
      },

      // onDone
      onDone: () {
        // Don't call close handler if connection was never established
        // We'll reject the connect call instead
        if (opened) {
          if (onClose != null) {
            onClose!();
          }
        } else {
          if (!websocketCompleter.isCompleted) {
            websocketCompleter
                .completeError('There was an error with the transport.');
          }
        }
      },
    );

    return websocketCompleter.future;
  }
