未定义 getter 'ws' - get_server

Question

我正在尝试使用get_server Flutter 包在我的 Flutter 应用程序中创建套接字服务器。

根据包文档，我试过this example，但它给了我像The getter 'ws' isn't defined for the class 'BuildContext'这样的错误

import 'package:get_server/get_server.dart';

void main() {
  final app = GetServer();
  app.get('/', (ctx) => Text('Get_server of javascript way'));
  app.ws('/socket', (res) {
    res.ws.listen((socket) {
      socket.onMessage((data) {
        print('data: $data');
      });

      socket.onOpen((ws) {
        print('new socket opened');
      });

      socket.onClose((ws) {
        print('socket has been closed');
      });
    });
  });
}

试试这个：

  final app = GetServer();
  app.get('/', (ctx) => Text('Get_server of javascript way'));
  app.ws('/socket', (ws) {
    ws.onMessage((data) {
      print('data: $data');
    });

    ws.onOpen((ws) {
      print('new socket opened');
    });

    ws.onClose((ws) {
      print('socket has been closed');
    });
  });
}
