json_factory_runtime_generator 0.3.2

Build-time JSON factory generator for json_serializable classes. Decodes JSON to the right class from a key in the JSON, with no base class, mixin or toJson changes.

0.3.2

• No code changes. Republished so pub.dev can verify the repository link, which 0.3.1 pointed at before the matching pubspec was on GitHub.

0.3.1

• The build stops when @JsonFactoryKey is on a method, getter or field. It was ignored, which left the class unregistered.
• The build stops when a class with @JsonFactoryKey extends a class with a @jsonFactoryKey field. Its toJson() wrote the parent's key, so the JSON decoded back to the parent.

0.3.0

• @JsonFactoryKey('key') registers a class with no key field. Its toJson() doesn't write the key, so use toJsonForFactory.
• Each mixin and mapper gets toJsonForFactory(object), which adds the key for the exact type of object. It works for classes using either annotation.
• The aggregator now runs before json_serializable, so @JsonKey(toJson: JsonFactoryMapper.toJsonForFactory) can resolve the mapper.
• The generated file also imports the registered classes' own libraries.
• Requires json_factory_runtime_annotation 0.3.0.

0.2.0

• Breaking: the default mixin is now JsonFactoryMixin (was JsonFactoryMapper). Replace with JsonFactoryMapper with with JsonFactoryMixin, or call the new static class instead.
• Each mixin gets a static mapper class, so no wrapper class is needed: JsonFactoryMapper.fromKeyedJsonAs<User>(json). A trailing Mixin in the mixin name becomes Mapper (ApiMixin → ApiMapper); other names get Mapper appended. instance holds the mixin as a const object. The build stops if a mapper name clashes with a mixin name or another mapper.
• Breaking: @jsonFactoryKey goes on a final String field initialized with a string literal. Replace String get factoryKey => 'user'; with final String factoryKey = 'user';. Getters now stop the build.
• @jsonFactoryKey is also accepted on a final enum field initialized with a constant that has a string @JsonValue.
• The build stops when a concrete @JsonSerializable subclass of a registered class has no @jsonFactoryKey field of its own.
• A class with a @jsonFactoryKey field but no fromJson of its own uses the nearest superclass's fromJson.
• Works with build 4.0.11+ and source_gen 4.2.4+ as well, for projects that also use builders not yet on build 5.
• Requires json_factory_runtime_annotation 0.2.0.

0.1.0

• Initial release.
