I have 2 overlay pages on my game.
There is a button on the first page that takes you to the second page.
On the second page there's a button that opens up a dialog that ask you to input a name.
To go back to the first page, I use WillPopScope to detect the back key being pressed.

Current bug behavior

After opening the keyboard to input a name, the WillPopScope doesn't work.
Only if I don't select the TextField (thus not opening the keyboard) the WillPopScope will work.
Just opening the dialog does not cause the error.

Expected behavior

WillPopScope should still work even after opening the keyboard.

Steps to reproduce

Run this program on Android:

import 'package:flutter/material.dart';
import 'package:flame/events.dart';
import 'package:flame/game.dart';

void main() {
  runApp(MaterialApp(home: Scaffold(body: GameWidget<Engine>.controlled(
    gameFactory: Engine.new,
    initialActiveOverlays: const ["Page 1"],
    overlayBuilderMap: {
      "Page 1": (_, engine) => Page1(engine: engine),
      "Page 2": (_, engine) => Page2(engine: engine),
    },
  ))));
}

class Engine extends FlameGame with ScaleDetector {
  void changePage(String add, String remove) {
    overlays.remove(remove);
    overlays.add(add);
  }
}

class Page1 extends StatelessWidget {
  final Engine engine;
  const Page1({super.key, required this.engine});
  @override
  Widget build(BuildContext context) {
    return Center(child: ElevatedButton(
      onPressed: () => engine.changePage("Page 2", "Page 1"),
      child: const Text("Go to Page 2"),
    ));
  }
}

class Page2 extends StatelessWidget {
  final Engine engine;
  final TextEditingController field = TextEditingController();
  Page2({super.key, required this.engine});
  @override
  Widget build(BuildContext context) {
    return WillPopScope(
      onWillPop: () async {
        engine.changePage("Page 1", "Page 2");
        return false;
      },
      child: Center(child: ElevatedButton(
        onPressed: () {
          showDialog(context: context, builder: (BuildContext context) {
            return AlertDialog(
              title: const Text("Input your name:"),
              content: TextField(controller: field),
              actions: <Widget>[TextButton(
                onPressed: () {
                  print("Hello ${field.text}!");
                  Navigator.pop(context);
                },
                child: const Text("OK"),
              )],
            );
          });
        },
        child: const Text("Show Dialog"),
      )),
    );
  }
}
