UI Tests compatible with GoRouter

[diarmaidlindsay]

Currently, when clicking on a Top Anime News Item in a UI Test, the following error occurs :

The following assertion was thrown while handling a gesture:
No GoRouter found in context
'package:go_router/src/router.dart':
Failed assertion: line 297 pos 12: 'inherited != null'

This is because the UI Test renders a specific page by specifying it in the home parameter of the MaterialApp.

await tester.pumpWidget(
    ProviderScope(
      overrides: [
        myAnimeListRepositoryProvider
            .overrideWithValue(_mockMyAnimeListRepository)
      ],
      child: const MaterialApp(
        **home: TopAnimePage()**,
      ),
    ),
  );

However, MaterialApp.goRouter() has no such home field, so a starting page for the UI Test cannot be specified as above.
A way must be investigated to write GoRouter UI Tests, or abandon that idea and just test each screen as a separate entity (which might be best).
