Explain an interface in dart with an example?

Dart - Interview Questions

Unlike other languages dart does not have any interface keyword, You can implement it with an abstract keyword

abstract class Joker{
  void makePeopleLaugh();
}

class Clown implements Joker{
  void makePeopleLaugh() {
    // Here is where the magic happens
  }
}

class Comedian implements Joker{
  void makePeopleLaugh() {
    // Here is where the magic happens
  }
}â€‹
