除了普通的HTTP請求，我們還可以使用WebSockets連接到伺服器。 WebSocket允許與伺服器進行雙向通信，而無需輪詢。

在此示例中，我們將連接到websocket.org提供的測試伺服器。伺服器將簡單地發送回我們發送給它的相同消息！

如有需要，請務必在評論中尋求幫助。也歡迎將來的Flutter教程提出建議！ 🙂

Flutter是Google擁有的SDK，可使用單個代碼庫為Android和iOS創建應用程序。 Flutter使用Dart編程語言（也歸Google擁有）。當我發布此視頻時，Flutter處於Alpha狀態，因此情況可能仍會有所變化。但是，SDK已經足夠成熟，可以編寫一些很棒的生產應用程序！

  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.
