Dart Enumeration : Enhanced Enums

Enhanced Enums :

• In dart, you can declare enums with members.

• For example, for your accounting software you can store company types like Sole Proprietorship, Partnership, Corporation, and Limited Liability Company.

• You can declare an enum with members as shown below.

enum Color {
  red,
  green,
  blue,
}

extension ColorExtension on Color {

  String get displayName {

    switch (this) {
      case Color.red:
        return 'Red';
      case Color.green:
        return 'Green';
      case Color.blue:
        return 'Blue';
      default:
        throw ArgumentError('Unknown color: $this');
    }
  }

}

void main() {
  print(Color.red.displayName); 
}
