我使用这个包，它在测试网站上正常工作，但在应用程序中我得到了这个错误

WebSocketException: Connection to 'https://socket.excopro.com:0/socket.io/?EIO=3&transport=websocket#' was not upgraded to websocket

这是我的代码

SocketService() {
    var socket = io(
        'https://socket.excopro.com:443/', <String, dynamic>{
      'transports': ['websocket'],
      'autoConnect': true,
    });
    socket.on('connect', (_) {
      print('connect');
      socket.emit('msg', 'test');
    });
      socket.on("connecting", (data) => print('connecting'));
      socket.on('connect_error', (data) {
        print(data);
        socket.emit('msg', 'test');
      }); 
  }
