toJson fromJson support

[Sangam Kumar Shrestha]

When using Formz along with hydrated bloc we can not hydrate state. We need to add toJson fromJson on every input.

It would be great if formz input supports it.

Sorry for my the stupid issue. Since fromJson is not possible in abstract class the best way is to write fromJson, toJson manually. If using json_serializable create a custom converter like this.

class NameInputConverter
    extends JsonConverter<NameInput, Map<String, dynamic>> {

  const NameInputConverter();

  NameInput fromJson(Map<String, dynamic> json) {
    return jsonDecode(json['pure'])
        ? const NameInput.pure()
        : NameInput.dirty(jsonDecode(json['value']));
  }

  Map<String, dynamic> toJson(NameInput input) {
    return {
      'value': jsonEncode(input.value),
      'pure': jsonEncode(input.pure),
    };
  }
}
