const JsonKey(
  1. {@Deprecated('Has no effect') bool? nullable,
  2. Object? defaultValue,
  3. bool? disallowNullValue,
  4. Function? fromJson,
  5. bool? ignore,
  6. bool? includeIfNull,
  7. String? name,
  8. Object? readValue(
    1. Map,
    2. String
    )?,
  9. bool? required,
  10. Function? toJson,
  11. Enum? unknownEnumValue}
