Dart multiple inheritance

Dart doesn’t support multiple inheritance . Multi-level − A class can inherit from another child class.

Dart supports polymorphism . Polymorphism allows a family of objects to adhere to a single interface while allowing different implementations. Let’s add another concrete class named Plane (Figure 4.1).28 Oca 2016

Types of Polymorphism

Method overriding occurs in dart when a child class tries to override the parent class’s method . When a child class extends a parent class, it gets full access to the methods of the parent class and thus it overrides the methods of the parent class.
