invalid_use_of_visible_for_overriding_member

The member '{0}' can only be used for overriding.

The analyzer produces this diagnostic when an instance member that is annotated with visibleForOverriding is referenced outside the library in which it's declared for any reason other than to override it.

Given a file a.dart containing the following declaration:

import 'package:meta/meta.dart';

class A {
  @visibleForOverriding
  void a() {}
}

The following code produces this diagnostic because the method m is being invoked even though the only reason it's public is to allow it to be overridden:

import 'a.dart';

class B extends A {
  void b() {
    a();
  }
}

Remove the invalid use of the member.
