DO annotate overridden methods and fields.
This practice improves code readability and helps protect against unintentionally overriding superclass members.
BAD:
class Cat {
int get lives => 9;
}
class Lucky extends Cat {
final int lives = 14;
}
GOOD:
abstract class Dog {
String get breed;
void bark() {}
}
class Husky extends Dog {
@override
final String breed = 'Husky';
@override
void bark() {}
}
