The method doesn't override an inherited method.

Description
#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.
Example
#The following code produces this diagnostic because m
isn't declared in any of the supertypes of C
:
class C {
@override
String m() => '';
}
Common fixes
#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.
If the member can't be removed, then remove the annotation.
