Flutter 对话框未完全关闭

Question

We have a Flutter dialog that when we click Ok and it sends the user home... the dialog lingers on the screen even after sending them home and then goes away which is annoying.

Here is the code for the dialog:

 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

在推送到新路线之前，尝试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,)));
