如何在FlatButton单击时关闭AlertDialog?

问题描述

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,
                ),
              ],
            ),
        );

如何让_dismissDialog()拒绝说AlertDialog?

推荐答案

应该可以解决问题.您还可以使用它返回对话框的结果(如果对话框为用户提供了选择)

Navigator.pop() should do the trick. You can also use that to return the result of the dialog (if it presented the user with choices)
