🎛️ Mixin

What are mixins?

A mixin is just like a class, it can have methods and properties, but it can’t be instantiated.

mixin Strong {
  bool doesLift = true;

  void benchPress() {
    print('doing bench press...');
  }
}

mixin Fast {
  bool doesRun = true;

  void sprint() {
    print('running fast...');
  }
}

What are mixins used for?

Mixins are used to extend specific behaviors to classes with the with keyword. Certain Flutter libaries use mixins to extend shared behaviors to classes.

class Human {}

class SuperHuman extends Human with Strong, Fast {}
