Is Dart similar to C++?

Dart has the ability to implement several interfaces . The keyword implements allows a class to adhere to multiple interfaces and increase an object’s polymorphic range. The keyword implement is followed by an existing named class whose public fields then become implementation requirements for the current class.

Dart has no interface keyword . Instead, all classes implicitly define an interface. Therefore, you can implement any class.

An interface defines the syntax that any entity must adhere to . Interfaces define a set of methods available on an object. Dart does not have a syntax for declaring interfaces. Class declarations are themselves interfaces in Dart. Classes should use the implements keyword to be able to use an interface.
