annotate_overrides

The member '{0}' overrides an inherited member but isn't annotated with '@override'.

The analyzer produces this diagnostic when a member overrides an inherited member, but isn't annotated with @override.

The following code produces this diagnostic because the method m in the class B overrides the method with the same name in class A, but isn't marked as an intentional override:

class A {
  void m() {}
}

class B extends A {
  void m() {}
}

If the member in the subclass is intended to override the member in the superclass, then add an @override annotation:

class A {
  void m() {}
}

class B extends A {
  @override
  void m() {}
}

If the member in the subclass is not intended to override the member in the superclass, then rename one of the members:

class A {
  void m() {}
}

class B extends A {
  void m2() {}
}
