Would be awesome to have a Widget Testing recipe in the readme!

I was trying to follow on old medium article linked in a stack overflow question to figure out how to write a widget test for a component that relies on CacheManager.

Unfortunately, it seems like a new version significantly changed the API and the recipe provided there is all kinds of broken. I wonder if it would be possible for someone to link from the readme a recipe for how to write such a test (possibly by implementing https://github.com/Baseflow/flutter_cache_manager/blob/develop/flutter_cache_manager/example/test/widget_test.dart and linking to it?)
