Return the element representing the method that results from looking up the method with the given name in the superclass of this class with respect to the given library, or null if the look up fails. The behavior of this method is defined by the Dart Language Specification in section 12.15.1:

The result of looking up method m in class C with respect to library L is: * If C declares an instance method named m that is accessible to L, then that method is the result of the lookup. Otherwise, if C has a superclass S, then the result of the * lookup is the result of looking up method m in S with respect to L. * Otherwise, we say that the lookup has failed.
