Add methods or values to enum in dart

Question

In java when you are defining an enum you can do something similar to the following. Is this possible in Dart?

enum blah {
  one(1), two(2);
  final num valu         


        

Answer 1

It may not be "Effective Dart" , I add a static method inside a Helper class ( there is no companion object in Dart) .

In your color.dart file

enum Color {
  red,
  green,
  blue
}

class ColorHelper{

  static String getValue(Color color){
    switch(color){
      case Color.red: 
        return "Red";
      case Color.green: 
        return "Green";
      case Color.blue: 
        return "Blue";  
      default:
        return "";
    }
  }

}

Since the method is in the same file as the enum, one import is enough

import 'package:.../color.dart';

...
String colorValue = ColorHelper.getValue(Color.red);
