Question

我们有一个Flutter对话框，当我们单击OK并将其发送给用户时，该对话框仍然停留在屏幕上，即使将他们发送回家后又消失了，这很烦人。

以下是对话框的代码：

 Future<void> _requestSupportDialog(BuildContext context, User user, Features features) {
    return showDialog<void>(
    context: context,
    builder: (BuildContext context) {
    return AlertDialog(
    title: Text('Success! You have been entered into the support queue'),
    content: const Text('Support it on its way'),
    actions: <Widget>[
      FlatButton(
        child: Text('Ok'),
        onPressed: () {
          // Send them HOME.
          Navigator.of(context).push(new MaterialPageRoute(builder: (BuildContext context) => new FlutterReduxApp(user: user, features: features)));
         },
        ),
      ],
    );
  },
);
}

Answer 1

Navigator.of(context, rootNavigator: true).pop();
Navigator.of(context).pushReplacement(MaterialPageRoute(builder: (BuildContext context)=>Home(son: 0,)));

Answer 2

在尝试使用新路线之前，请先弹出以关闭对话框。

Navigator.of(context).pop()

Answer 3

Navigator.of（context，rootNavigator：true）.pop（）;

Navigator.of（context）.pushReplacement（MaterialPageRoute（builder：（BuildContext context）=> Home（son：0，）））;

颤振对话框未完全关闭
