Flutter - How can I change the background color of LicensePage?

Question

I'd like to set the background colour of every screen except LicensePage to some colour, so I've specified the scaffoldBackbroundColor via the theme argument of MaterialApp as follows.

class App extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(scaffoldBackgroundColor: Colors.blue.shade200),
      home: HomeScreen(),
    );
  }
}

This changes the background colour of the licences page too, so in order to change it back to white, I tried overriding scaffoldBackbroundColor, but it did not work.

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Theme(
        data: Theme.of(context).copyWith(scaffoldBackgroundColor: Colors.white),
        child: Center(
          child: RaisedButton(
            child: const Text('Show licenses'),
            onPressed: () => showLicensePage(context: context),
          ),
        ),
      ),
    );
  }
}

How can I do it?

I came up with this and it worked successfully.

Scaffold(
  body: Center(
    child: RaisedButton(
      child: const Text('Show licenses'),
      onPressed: () => Navigator.of(context).push(
        MaterialPageRoute<void>(
          builder: (context) => Theme(
            data: Theme.of(context).copyWith(
              scaffoldBackgroundColor: Colors.white,
            ),
            child: LicensePage(...),
          ),
        ),
      ),
    ),
  ),
)
