Enum and Equatable incompatibility about dart-json-mapper

[bounty1342]

@k-paxian : Actually it's not related to Equatable, but rather to another corner case of a getter of a list of Object containing a Enum.

enum MyColor { black, red }

@jsonSerializable
class MyCarModel  {
  final String model;

  @JsonProperty(enumValues: MyColor.values)
  final MyColor color;

 const MyCarModel({this.model, this.color});

  List<Object> get myVal => [
        model,
        color,
      ];

  Map<String, dynamic> toJson() {
    return JsonMapper.toMap(this);
  }
}

Certainly because getter are consider like field, it's expecting an annotation for myVal.
The following works witch seems to confirm the expectation :

enum MyColor { black, red }

@jsonSerializable
class MyCarModel {
  final String model;

  @JsonProperty(enumValues: MyColor.values)
  final MyColor color;

  const MyCarModel({this.model, this.color});

  @JsonProperty(enumValues: MyColor.values)
  Object get props => color;

  Map<String, dynamic> toJson() {
    return JsonMapper.toMap(this);
  }
}

Since this bug is resolve, one easy way to make it compatible with Equatable is to add the 'ignore' @ on the getter containing Enum.

@jsonSerializable
class MyCarModel extends Equatable {
  final String model;

  @JsonProperty(enumValues: MyColor.values)
  final MyColor color;

  const MyCarModel({this.model, this.color});

  @JsonProperty(ignore: true)
  List<Object> get props => [
        model,
        color,
      ];

  Map<String, dynamic> toJson() {
    return JsonMapper.toMap(this);
  }
}

Hope this findings will help you and other users. 😃

So nice to see clean and concise model code 😄
