It's valid to override a member in the following cases:
- if a type (return type or a parameter type) is not the exactly the same as the super member,
- if the
covariant
keyword is added to one of the parameters, - if documentation comments are present on the member,
- if the member has annotations other than
@override
, - if the member is not annotated with
@protected
, and the super member is.
noSuchMethod
