What is the function of @override?

• The annotation @override marks an instance member as overriding a superclass member with the same name. Example

class A {
  void foo() {
    print("Class A");
  }
}

class B extends A {}

class C extends A {
  @override foo() {
    print("Class C");
  }
}

void main() {
  A a = A();
  B b = B();
  C c = C();
  a.foo();
  b.foo();
  c.foo();
}

Output

Class A
Class A
Class C
