MaterialScreenWidgetDirector<Args> class

A specialized TestDirector for testing Flutter widgets that require a MaterialApp wrapper.

This director automatically wraps the target widget with a MaterialApp, making it suitable for testing screens or full-page widgets that depend on Material Design context.

Usage:

void main() {
  late MaterialScreenWidgetDirector<(String, String)> director;

  setUp(() {
    director = MaterialScreenWidgetDirector<(String, String)>()
      ..setUnitFactory((args) => MyScreen(title: args.$1, subtitle: args.$2));
  });

  testWidgets('MyScreen displays correctly', (WidgetTester tester) async {
    director.setArgs(('Test Title', 'Test Subtitle'));
    await tester.pumpWidget(director.construct());
    // Perform your test assertions here
  });
}
