override_on_non_overriding_member

The field doesn't override an inherited getter or setter.

The getter doesn't override an inherited getter.

The method doesn't override an inherited method.

The setter doesn't override an inherited setter.

The analyzer produces this diagnostic when a class member is annotated with the @override annotation, but the member isn't declared in any of the supertypes of the class.

The following code produces this diagnostic because m isn't declared in any of the supertypes of C:

class C {
  @override
  String m() => '';
}

If the member is intended to override a member with a different name, then update the member to have the same name:

class C {
  @override
  String toString() => '';
}

If the member is intended to override a member that was removed from the superclass, then consider removing the member from the subclass.
