Does the Dart language support the concept of multiple class inheritance?

In the Dart language, multiple inheritance of classes is not supported. A class can only inherit from one superclass.

However, Dart provides a mechanism called mixins, which allows adding functionality from multiple sources without using multiple inheritance.

Example of using mixins:

mixin A {
  void methodA() => print('A');
}

mixin B {
  void methodB() => print('B');
}

class C with A, B {}

void main() {
  var c = C();
  c.methodA(); // Prints 'A'
  c.methodB(); // Prints 'B'
}

Thus, in Dart, mixins are used for code reuse instead of multiple class inheritance.
