How to find all classes implementing an interface in Dart standard library?

I might be missing something, but how do you find all classes implementing an interface or extending a class in Dart API reference documentation?

Say, there is an abstract OutlinedBorder class. How do you find all classes derived from it? e.g. RoundedRectangleBorder and the like.
