Description
Steps to reproduce
- Android Studio > File > New > New Flutter Project... > Flutter > Next > Create > default Flutter Demo ("Normal counter app") created.
- In order to switch between pages, add 'Navigator.push()' to '_incrementCounter()'.
- Build and Run
- Android Emulator > Medium Phone API 35 > Click the plus button at the bottom of right side > Power Button Click (to screen off) > Power Button Click (to screen on)

Normal counter app with Navigator.push
Regardless of screen on/off, counter app's pushed page text should not be broken.
Actual results

}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(

}
class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;
void _incrementCounter() {
setState(() {
_counter++;
});

// Below code is only one added to default Counter App example.
Navigator.push(context,
MaterialPageRoute(builder: (context) => Scaffold(
appBar: AppBar(title: Text('I am a title')),
body: Text('See both title and text are broken after screen off/on'),
),
),
);
