how to add enum builder, please help me.

type '(Map<dynamic, dynamic>) => MyEnum' is not a subtype of type '((Map<dynamic, dynamic>) => CvModel)?' in type cast

or open any type builder

I'm not sure what you are trying to achieve and how to help you but a field in a model could be an enum, however it cannot be converted to json.
One solution is to use CvField.encoded that allows encoding any type into something else during model.toMap/fromMap.

As of 1.1.9 - just published -, I have added CvField.encodedEnum with will export the value as a string and allow json serialization.

Simple example:

import 'package:cv/cv_json.dart';

enum MyEnum { optionA, optionB, optionC }

class MyModel extends CvModelBase {
  /// String
  final name = CvField<String>('name');

  /// Enum converted to string in the map
  final status = CvField.encodedEnum<MyEnum>('status', MyEnum.values);

  @override
  CvFields get fields => [name, status];
}

Future<void> main(List<String> args) async {
  cvAddConstructor(MyModel.new);

  var model = MyModel();
  model.name.v = 'Test Name';
  model.status.v = MyEnum.optionB;
  print(model.toJsonPretty());
  // {"name":"Test Name","status":"optionB"}

  /// From json
  model = '{"name":"Test Name","status":"optionC"}'.cv<MyModel>();
  print(model.name.v); // Test Name
  print(model.status.v); // MyEnum.optionC
}

Maybe i did not understand your needs, let me know!
