Enum Classes for Dart

Enum Classes are an extension to Dart that uses code generation to give common enum functionality to classes.

Features

• Constants have name and toString, can be used in switch statements, and are real classes that you can add code to
• Generated values method that returns all the enum values in a BuiltSet (immutable set)
• Generated valueOf method that takes a String

Using Enum Classes

Enum Classes use the source_gen library for code generation. The typical way to use it is via a build.dart tool that you create for your project. When you run it, all the generated files are updated.

Here's what you need to do to use Enum Classes:

1. Add a library dependency on enum_class to your pubspec.yaml
2. Add a dev dependency on enum_class_generator to your pubspec.yaml
3. Create a build.dart for your project. See example, below.
4. Run pub run tools/build.dart whenever you need to update the generated files.
5. To make an Enum Class, import package:enum_class/enum_class.dart then extend EnumClass.

See this example for a full project with a build.dart and an enum.
