How can I show a flash on top of an alert dialog?

[CurrySenpai]

Currently the flash is shown behind the dialog

import 'package:flash/flash.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: Home(),
    );
  }
}

class Home extends StatelessWidget {
  const Home({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RaisedButton(
          onPressed: () {
            showDialog(
              context: context,
              builder: (_) => AlertDialog(
                content: RaisedButton(
                  onPressed: () {
                    showFlash(
                      context: context,
                      duration: Duration(seconds: 3),
                      persistent: true,
                      builder: (_, controller) {
                        return Flash(
                          controller: controller,
                          child: FlashBar(
                            message: Text('Hello Flash'),
                          ),
                        );
                      },
                    );
                  },
                  child: Text('Show Flash'),
                ),
              ),
            );
          },
          child: Text('Show Dialog'),
        ),
      ),
    );
  }
}

Hi @CurrySenpai , I ran your code, Flash is at the top.

@sososdk thanks for check,
Are you using flutter stable 1.17 - 1.17.1 ?
I would believe that the error arose in this version, because before updating I did not notice it
