WillPopScope on Android Doesn't Work After Opening Keyboard on a Dialog

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.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: [TextButton(
onPressed: () {
print("Hello ${field.text}!");
Navigator.pop(context);
},
child: const Text("OK"),
)],
);
});
},
child: const Text("Show Dialog"),
)),
);
}
}
```
