Subject: [PATCH] Add test for scaffold.0.dart and scaffold.2.dart (#148166)

Contributes to https://github.com/flutter/flutter/issues/130459

It adds test for
- `examples/api/lib/material/scaffold/scaffold.0.dart`
- `examples/api/lib/material/scaffold/scaffold.2.dart`

It also modifies the `scaffold.1_test.dart` because the only difference with scaffold 0 is the background color, so I figured the test should include it
