除了普通的HTTP请求，我们还可以使用WebSockets连接到服务器。 WebSocket允许与服务器进行双向通信，而无需轮询。

在此示例中，我们将连接到websocket.org提供的测试服务器。服务器将简单地发送回我们发送给它的相同消息！

侦听来自服务器的消息
发送数据到服务器
关闭WebSocket连接

如有需要，请务必在评论中寻求帮助。也欢迎将来的Flutter教程提出建议！ 🙂

Flutter是Google拥有的SDK，可使用单个代码库为Android和iOS创建应用程序。 Flutter使用Dart编程语言（也归Google拥有）。当我发布此视频时，Flutter处于Alpha状态，因此情况可能仍会有所变化。但是，SDK已经足够成熟，可以编写一些很棒的生产应用程序！

  3. Hello sir,

    Sorry it might be a newbie question.

    If the application is run on more than one client,

    and every time there is added data to server, will each client's widget be rebuilt ?

    In other words

    If a client adds data to server, will all client's widgets be rebuilt ?

    Thank you for your attention.
