I was looking for a sub issue for the cross imports cleanup project, relating specifically to the examples directory, but couldn't find one linked in Decoupling Design (view) nor on Github search, so I'm going to file one here. cc @justinmc if you recall there being one?

We have existing checks that verify cross imports for tests in Flutter itself, tests in flutter_test (#187587 will address that) and one for doc imports (#181288)

However, cross imports in /examples (of which examples/api is probably the most well-known case)
should also be checked.
