Dart encapsulation

Polymorphism is exemplified in Dart by the @override metatag . With it, a subclass’s implementation of an inherited behavior can be specialized to be appropriate to its more specific subtype. When a class has properties that are themselves instances of other classes, it’s using composition to add to its abilities.10 Tem 2020

Polymorphism is one of the core concepts of object-oriented programming (OOP) and describes situations in which something occurs in several different forms . In computer science, it describes the concept that you can access objects of different types through the same interface.

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

The polymorphism is a combination of the two Greek words poly, which means many and morph means morphing into different forms or shapes . Together, polymorphism means the same entity can be used in various forms. In the programming aspect, the same method can be used in different classes.
