android - 如何在 FlatButton 单击时关闭 AlertDialog？

Question

我有以下 AlertDialog。

showDialog(
            context: context,
            child: new AlertDialog(
              title: const Text("Location disabled"),
              content: const Text(
                  """
Location is disabled on this device. Please enable it and try again.
                  """),
              actions: [
                new FlatButton(
                  child: const Text("Ok"),
                  onPressed: _dismissDialog,
                ),
              ],
            ),
        );

我怎样才能让 _dismissDialog() 关闭所说的 AlertDialog？

Answer 1

Navigator.pop()应该做的伎俩。您还可以使用它来返回对话框的结果(如果它为用户提供了选择)
