Proof that Dart enum extension works

main.dart

enum FruitType {
  orange,
  apple,
  guava,
}

extension FruitTypeDescriptions on FruitType {
  String get name {
    switch (this) {
      case FruitType.orange:
        return "Orange";
      case FruitType.apple:
        return "Apple";
      case FruitType.guava:
        return "Guava";
    }
  }
  
  String unitNameForAmount(int amount) {
    if (amount == 1) {
      return name;
    } else {
      return name + "s";
    }
  }
  
  String isSimilarTo(FruitType otherFruit) {
    if (this == otherFruit) {
      return "Yes";
    } else {
      return "No";
    }
  }
}

void main() {
  for (FruitType fruitType in FruitType.values) {
    print("## $fruitType");
    print("Name: ${fruitType.name}");
    print("Plural Form: ${fruitType.unitNameForAmount(2)}");
    print("Similar to guava: ${fruitType.isSimilarTo(FruitType.guava)}");
    print("");
  }
