Features and bugs

Please file feature requests and bugs at the issue tracker.

1.1.0

  • Added the fieldRename option to JsonSerializable and the associated FieldRename enum.

1.0.0

  • Added JsonValue class for annotating enum fields with a custom serialization value.

  • Removed $checkAllowedKeys, $enumDecode and $enumDecodeNullable which are no longer needed by the latest release of package:json_serializable.

0.2.9+1

  • Support the Dart 2.0 stable release.

0.2.9

  • When FormatException is caught in "checked mode", use the message property when creating CheckedFromJsonException.

0.2.8

  • Added $checkKeys helper function and deprecated $checkAllowedKeys. Upgrading to the latest json_serializable and re-running your build will eliminate any @deprecated hints you see.

  • Added BadKeyException exception which is the abstract super class for MissingRequiredKeysException, UnrecognizedKeysException, and DisallowedNullValueException.

  • Added JsonKey.required field and an associated MissingRequiredKeysException that is thrown when required fields don't have corresponding keys in a source JSON map.

  • Added JsonKey.disallowNullValue field and an associated DisallowedNullValueException that is thrown when corresponding keys exist in a source JSON map, but their values are null.

  • Updated documentation of JsonSerializable.createToJson to include details of the new generate_to_json_function configuration option.

0.2.7+1

  • Small improvement to UnrecognizedKeysException.message output and documentation comments.

0.2.7

  • Added JsonSerializable.disallowUnrecognizedKeys.
    • Added a helper function to support this option. This function starts with a $ and should only be referenced by generated code. It is not meant for direct use.
    • Added UnrecognizedKeysException for reporting errors.

0.2.6

  • CheckedFromJsonException

    • Added a public constructor to support hand-written JSON decoding logic.
    • The message property is now String (instead of Object).
  • Added JsonKey.defaultValue.

  • Added helpers for deserialization of enum values. These functions starting with $ are referenced by generated code. They are not meant for direct use.

0.2.5

  • Added CheckedFromJsonException which is thrown by code generated when checked is enabled in json_serializable.

  • Added functions to support the checked generation option. These functions starting with $ are referenced by generated code. They are not meant for direct use.

0.2.4

  • Added fromJson and toJson fields to JsonKey class.

0.2.3

  • Added ignore field to JsonKey class annotation

0.2.2

  • Added a helper class – $JsonMapWrapper – and helper functions – $wrapMap, $wrapMapHandleNull, $wrapList, and $wrapListHandleNull – to support the useWrappers option added to JsonSerializableGenerator in v0.3.0 of package:json_serializable.

0.2.1

  • JsonSerializable class annotation
    • Added nullable field.
    • Fixed doc comment.

0.2.0

  • Moved annotation classes for JsonSerializable and JsonLiteral.
