Value types with builders, Dart classes as enums, and serialization. This library is the runtime dependency.

Changelog #

8.9.2 #

  • Improve build performance when there are lots of built_value classes.

8.9.1 #

  • Fix for new warning about operator== param type.

8.9.0 #

  • In StandardJsonPlugin, add support for specifying types that should be left as List.
  • Allow non alphanumeric characters in EnumClass names.

8.8.1 #

  • Fix codegen for enum wire keys when there is a $ in the field name.
  • Remove support for generating legacy (<2.12) Dart code.

8.8.0 #

  • Allow classes with record fields to be serialized if they use a typedef for the record type and install a custom Serializer for it.

8.7.0 #

  • Add Int32 serializer.

8.6.3 #

  • Bump version of analyzer.

8.6.2 #

  • Remove JSON from DeserializationError message to prevent data accidentally leaking into logs. The JSON is still available on the DeserializationError object.
  • Fix generation for fields that are Function types that are declared separately, for example in a mixin defined in another source file, and use named or positional parameters.

8.6.1 #

  • Fix support for generating enum mixins for Dart 3. Instead of triggering mixin generation with abstract class TestEnumMixin = Object with _$TestEnumMixin it must now be triggered with typedef TestEnumMixin = _$TestEnumMixin.

8.6.0 #

  • Add support for value types with record fields. Serialization with records is not yet supported.
  • Fix generator failure due to top level record field.
  • Migrate benchmark and examples to null safety.
  • Remove pre-null-safe test cases.
  • Remove analyzer plugin.
  • Remove reference to @nullable annotation from failure-to-instantiate message.

8.5.0 #

  • Add Uint8ListSerializer.
  • Generate Dart-3-compatible code if needed.
  • Stop using deprecated analyzer API.
  • Fix codegen for optional fields with $ in the name.

8.4.4 #

  • Increase minimum version of analyzer.
  • Fix generation with the type Never.

8.4.3 #

  • Fix generated deserialization code when there is a manually written builder with nullable fields.
  • Drop dev dependency on quiver.
  • Disable all linting of generated code.
  • Change generated hash code implementation so it formats better when there are many fields.

8.4.2 #

  • Prepare for breaking analyzer changes.
  • Bump version of analyzer.

8.4.1 #

  • Bump version of analyzer.

8.4.0 #

  • Fix custom builders in null safe code: allow nested builder fields to be nullable.
  • Improve custom builders for null safe code: allow abstract setter/getter pairs instead of fields. This allows nested builders to have a setter that accepts null and a getter that guarantees not to return null, which is what auto instantiation of nested builders already provides.
  • Allow use of super field initialization in EnumClass.

8.3.3 #

  • Fix erroneously generated null check for fields with generic bounds.

8.3.2 #

  • Migrate built_value_test to null safety.

8.3.1 #

  • Fix generation support for optional generic bounds, e.g. class Foo<T extends Object?>.
  • Fix generation for classes with names starting $.
  • Ignore lint unnecessary_lambdas in generated code.

8.3.0 #

  • Change generated build methods to return only public types, creating _build methods that return the generated impl types. This means dartdoc will no longer reference the generated types.
  • Ignore the no_leading_underscores_for_local_identifiers lint in generated code.
  • Migrated built_value_generator to null safety. This is purely an internal change, the generator can still generate legacy code as and when needed.

8.2.3 #

  • Bug fix: fix a corner case with generics that had incorrect serializer generation.

8.2.2 #

  • Bug fix: remove a print from the enum generator.

8.2.1 #

  • Fix deps: allow built_value_generator to use built_value 8.2.0.

8.2.0 #

  • Allow writing final parameters in EnumClass constructor and valueOf method.
  • Make generator output additional explicit null checks so the generated code complies with the cast_nullable_to_non_nullable lint.
  • Bump version of analyzer.

8.1.4 #

  • Bump version of analyzer.

8.1.3 #

  • Bump version of analyzer, fix deprecation warnings.

8.1.2 #

  • Bump version of analyzer.

8.1.1 #

  • Bug fix: allow constructors to have annotations. Previously, annotations would cause codegen to fail.

8.1.0 #

New features:

  • Add @BuiltValueHook annotation. It provides the same functionality as _initializeBuilder and _finalizeBuilder, but in a more visible way: annotate a static method on the value class with @BuiltValueHook to have it called on builder creation or finalization.
  • Add back serializeNulls to BuiltValueSerializer annotation. By default generated serializers skip null fields instead of writing them; set serializeNulls to write the nulls.

New minor functionality:

  • Support use of nulls in collections when the key or value types are explicitly nullable.
  • Allow JsonObject to be instantiated from a Map<dynamic, dynamic>.
  • Mark nested builder getters in instantiable: false classes not nullable, to match the implementations. Use autoCreateNestedBuilders: false to get the old behaviour.
  • Allow explicit nulls in JSON for nullable fields when deserializing.
  • Specify annotation targets; the analyzer will now hint if a built_value annotation is used where it has no effect.
  • Support polymorphism with mixed in parent value type: generated builder now mixes in parent builder.

Bug fixes:

  • Fix support for serializing and deserializing nulls.
  • Fix nestedBuilders: false with instantiable: false.
  • Fix enum deserialization fallback for int.
  • Annotating a wrong type getter with @SerializersFor is now an error, instead of just generating nothing.


  • Removed Angular mixin from example, as this feature is no longer needed: Angular now directly supports using static members in templates.

  • Remove dependency on package:quiver.
  • Remove support for serializing nulls using BuiltValueSerializer(serializeNulls: true).
  • Make installed plugins public in Serializers as serializerPlugins.
  • @memoized fields can now memoize null; previously, nulls would not be cached, causing the computation to rerun.

7.1.1 #

7.1.0 #

  • Support private Built classes. Note that private classes cannot be made serializable.
  • Support serializing enums to ints: add wireNumber to @BuiltValueEnumConst.
  • Support memoizing hashCode, so it's computed lazily once. Write an abstract getter int get hashCode; then annotate it with @memoized to turn this on for a built_value class.
  • Trim built_value_test dependencies: depend on matcher instead of test.
  • Fix enum generator error messages when value and valueOf are missing.

7.0.9 #

  • Fix unescaped string usages while generating ValueSourceClass.
  • Fix analyzer use: don't rely on toString on types.

7.0.8 #

7.0.7 #

  • Fix regression in a corner case when determining which fields to generate based on mixins.
  • Tweak generation changes for implicit-casts: false and implicit-dynamic: false. Relax casts again where possible.

7.0.6 #

  • Make generated code comply with analyzer option strict-raw-types.
  • Allow Serialiers declaration to comply with strict-raw-types, or to continue to use raw types as before.
  • Make generated code comply with analyzer options implicit-casts: false and implicit-dynamic: false.

7.0.5 #

  • Internal: fix analyzer deprecation warnings.

7.0.4 #

  • Split analysis plugin out into new package, built_value_analyzer_plugin. Bump built_value_generator dependency on analyzer to 0.39.0 so it supports extension methods.

7.0.3 #

  • Add example folders with README.md pointing to examples.

7.0.2 #

  • Internal: cleanup for pedantic v1.9.0 lints.

7.0.1 #

  • Internal: cleanup for pedantic v1.9.0 lints.

7.0.0 #

  • Internal: clean up built_value_generator -> built_value dependency; depend on minor instead of major version so we can in future handle tight coupling between the two without a major version bump to built_value.

  • Fix _finalizeBuilder generation so it uses the correct class name.

6.8.1 #

  • Fix missing README.md in package:built_value.

6.8.0 #

  • Add defaultCompare and defaultSerialize to @BuiltValue. They control the defaults for compare and serialize in @BuiltValueField.
  • Add facility to merge Serializers instances via Serializers.merge, SerializersBuilder.merge and SerializersBuilder.mergeAll.
  • Bug fix: fix generated code with polymorphism and more than one level of non-instantiable classes.
  • Bug fix: fix generated operator== when a field is called other.
  • Fix num deserialization so it does not always convert to double.

  • Fix codegen for custom builders when fields use types that have an import prefix.
  • Bump version of analyzer_plugin.

6.7.0 #

  • Generate code compatible with 'no raw types'.

6.6.0 #

  • Allow providing your own toString via a mixin.

  • Bump versions of analyzer, analyzer_plugin and build_config.

6.4.0 #

6.3.1 #

  • Fix BuiltList serialization when using StandardJsonPlugin with unspecified type and when list length is 1.

6.3.0 #

  • Make it possible to merge Serializers instances: add a serializers getter that returns the installed serializers.
  • Add serializer for RegExp fields.
  • Allow analyzer 0.34.0.

6.2.0 #

New features:

  • Add an option to @BuiltValue to generate comparable builders.

  • Add ignore for avoid_as lint to generated code.
  • Put ignored lints on a single line at the end of the generated output.

  • Fix library name output in generation error messages.
  • Add ignores for lints 'unnecessary_const' and 'unnecessary_new' to generated code.

6.0.0 #

  • Update to the latest source_gen. This generator can now be used with other generators that want to write to .g.dart files without a manual build script.
  • Breaking change: The "header" configuration on this builder is now ignored.

5.5.5 #

  • Allow SDK 2.0.0.

5.5.4 #

  • Add ignores for lints 'lines_longer_than_80_chars' and 'avoid_catches_without_on_clauses' to generated code.
  • Bump version of quiver.

5.5.3 #

  • Bump versions of build_runner, build_config and shelf.

  • Fix code generation when inherited generic fields are made non-generic.

5.4.5 #

  • Improve error message on failure to deserialize.
  • Move check forbidding instantiation with dynamic type parameters from builder to value class. Previously, you could avoid the check by using the generated constructor called _.

  • Removed dependency on build_config from built_value and added it to built_value_generator.

5.4.3 #

  • Allow source_gen 0.8.0.

5.4.2 #

  • Make StandardJsonPlugin return Map<String, Object>, as the firebase libraries expect, instead of Map<Object, Object>.

5.4.1 #

  • Fix analyzer plugin loading. It should now work, provided you modify your analysis_options.yaml as suggested.

5.4.0 #

  • Add an experimental analyzer plugin that surfaces compile time generation errors as suggestions in your IDE. Turn it on by modifying your analysis_options.yaml file to add plugins entries, example.

5.3.0 #

  • Support serializing BigInt.
  • Add support for setting the generated header in a build.yaml file in your project. See example/build.yaml for an example.
  • Explicitly forbid serialization of Function and typedef types; these fields need to be marked @BuiltValueField(serialize: false).
  • Fix generation when a field picked up via inheritance is a function type defined in another source file.
  • Fail with a helpful error message if @SerializersFor annotation list contains an undefined symbol.

5.2.2 #

  • Allow quiver 0.29.

5.2.1 #

  • Type fixes for DDC.

5.2.0 #

  • Note: this version requires the pre release of the Dart 2 SDK.

5.1.3 #

  • Generate simpler deserialization code for built_collection instances.

5.1.2 #

  • Fix generated serialization code when a manually declared builder causes a field to not use a nested builder.

5.1.1 #

  • Workaround for analyzer issue when implementing multiple classes that use @BuiltValue(instantiable: false).

5.1.0 #

  • Relax restriction on extends to allow for one special case: sharing of code between built_value and const classes. The base class in question must be abstract, have no fields, have no abstract getters and must not implement operator==, hashCode or toString.

5.0.1 #

  • Allow quiver 0.28.

5.0.0 #

Introduce restrictions on using built_value in unsupported ways:

  • Prohibit use of extends in built_value classes. Classes should inherit API using implements and API+implementation using extends Object with.
  • Prohibit use of show or as when importing 'package:built_value/built_value.dart'. The generated code needs access to all symbols in the package with no import prefix.
  • Prohibit use of the mutable collection types List, Set, Map, ListMultimap and SetMultimap. Suggest built_collection equivalents instead.

If any of these restrictions causes problem for you, please file an issue on github: https://github.com/google/built_value.dart/issues

4.6.1 #

  • Allow hand-coded base builders, that is, builders for classes with @BuiltValue(instantaible: false). They are now allowed to not implement Builder (as a workaround for a dart2js issue); they are allowed to omit fields; and they must omit constructor and factory.

4.6.0 #

  • Add custom Error classes: BuiltValueNullFieldError, BuiltValueMissingGenericsError and BuiltValueNestedFieldError. These provide clearer error messages on failure. In particular, errors in nested builders now report the enclosing class and field name, making them much more useful.
  • Fix serialization when using polymorphism with StandardJsonPlugin.

4.5.2 #

  • Allow built_collection 3.0.0.
  • Allow quiver 0.27.

4.5.1 #

  • Fix generation when analyzing using summaries.

4.5.0 #

New features:

  • Add serialize field to @BuiltValueField. Use this to tag fields to skip when serializing.
  • Add wireName field to @BuiltValue and @BuiltValueField. Use this to override the wire name for classes and fields when serializing.
  • Add @BuiltValueEnum and @BuiltValueEnumConst annotations for specifying settings for enums. Add wireName field to these to override the wire names in enums when serializing.
  • Add support for polymorphism to StandardJsonPlugin. It will now specify type names as needed via a discriminator field, which by defualt is called $. This can be changed in the StandardJsonPlugin constructor.
  • Add BuiltListAsyncDeserializer. It provides a way to deserialize large responses without blocking, provided the top level serialized type is BuiltList.
  • Add built in serializer for Uri.


  • Allow declaration of multiple Serializers in the same file.
  • Explicitly disallow private fields; fail with an error during generation if one is found.
  • Improve error message for field without type.


  • Fix generated builder when fields hold function types.
  • Fix checks and generated builder when manually maintained builder has generics.
  • Fix name of classes generated from a private class.
  • Fix builder and serializer generation when importing with a prefix.

4.4.1 #

  • Use build 0.11.1 and build_runner 0.6.0.

4.4.0 #

  • New annotation, BuiltValueField, for configuring fields. First setting available is compare. Set to false to ignore a particular field for operator== and hashCode.
  • Generator now has a const constructor.

4.3.4 #

  • Fix for built_collection 2.0.0.

4.3.3 #

  • Allow quiver 0.26.

4.3.2 #

  • Fix generation when a field is found via two levels of inheritance.

4.3.1 #

  • Fix generation when a field comes from an interface but is also implemented by a mixin.

4.3.0 #

  • Support serializing Int64.

4.2.1 #

  • Correct handling of import prefixes; fixes some corner cases in generation.

4.2.0 #

  • Generated code ignores more lints.
  • Add a workaround so "polymorphism" features can be used with dart2js. See example/lib/polymorphism.dart.
  • Deal explicitly with the user defining their own operator==, hashCode and/or toString(). Previously, they would just not work. Now, custom operator== and hashCode are forbidden at compile time, but custom toString() is supported.

4.1.1 #

  • Generated code now tells the analyzer to ignore prefer_expression_function_bodies and sort_constructors_first.
  • Remove an unneeded use of computeNode in generator; improves generator performance.

4.1.0 #

  • Improved annotation handling for corner cases.
  • Pick up field declarations from mixins as well as interfaces.

4.0.0 #

  • Fix generated polymorphic builders for the analyzer. Mark the rebuild method with covariant so the analyzer knows that, for example, a CatBuilder cannot accept an Animal.
  • Update to build 0.10.0 and build_runner 0.4.0. Please update your build.dart and watch.dart as shown in the examples.

3.0.0 #

  • Fix DateTime serialization; include microseconds. This is a breaking change to the JSON format.
  • Add SerializersFor annotation. Classes to serialize are no longer found by scanning all available libraries, as this was slow and hard to control. Instead, specify which classes you need to serialize using the new annotation on your "serializers" declaration. You only need to specify the "root" classes; the classes needed for the fields of classes you specify are included, transitively.

2.1.0 #

  • Add "nestedBuilders" setting. Defaults to true; set to false to stop using nested builders by default in fully generated builders.
  • Allow fields to be called 'result'.
  • Fix generation when a field is a noninstantiable built value: don't try to instantiate the abstract builder.

2.0.0 #

  • Update to source_gen 0.7.0.
  • Please make the following trivial update to your build.dart and watch.dart: replace the string GeneratorBuilder with PartBuilder.

1.2.1 #

  • Fix generated code when implementing generic non-instantiable Built class.

1.2.0 #

  • Fix depending on a fully generated builder from a manually maintained builder.
  • Pick up fields on implemented interfaces, so you don't have to @override them.
  • Add BuiltValue annotation for specifying settings.
  • Add "instantiable" setting. When false, no implementation is generated, only a builder interface.
  • Polymorphism support: you can now "implement" a non-instantiable Built class. The generated builder will implement its builder, so the types all work.

1.1.4 #

  • Require SDK 1.21 and use the non-comment syntax for generics again.

1.1.3 #

  • Removed dependency on now-unneeded package:meta.
  • Fixed a few lints/hints in enum generated code.
  • Use comment syntax for generics; using the non-comment syntax requires SDK 1.21 which is not specified in pubspec.yaml.

1.1.2 #

  • Significantly improve build performance by using @memoized instead of precomputed fields.

1.1.1 #

  • Update analyzer and build dependencies.

1.1.0 #

  • Add "built_value_test" library. It provides a matcher which gives good mismatch messages for built_value instances.

1.0.1 #

  • Allow quiver 0.25.

1.0.0 #

  • Version bump to 1.0.0. Three minor features are marked as experimental and may change without a major version increase: BuiltValueToStringHelper, JsonObject and SerializerPlugin.
  • Made toString() output customizable.
  • Made the default toString() output use indentation and omit nulls.
  • Sort serializers in generated output.

0.5.7 #

  • Ignore nulls when deserializing with StandardJsonPlugin.

0.5.6 #

  • Add serializer for "DateTime" fields.
  • Add JsonObject class and serializer.
  • Add convenience methods Seralizers.serializeWith and deserializeWith.
  • Add example for using StandardJsonPlugin.
  • Support serializing NaN, INF and -INF for double and num.

0.5.5 #

  • Add serializer for "num" fields.
  • Better error message for missing serializer.
  • Fix generation when there are nested multi-parameter generics.
  • Use cascades in generated code as suggested by lint.
  • Allow users to define any factory that references the generated implementation.
  • Add example of a simpler factory for a one-field class.

0.5.4 #

  • Enforce that serializer declarations refer to the right generated name.
  • Streamline generation for classes with no fields.
  • Add identical check to generated operator==.
  • Make generated code compatible with strong mode implicit-dynamic:false and implicit-cast:false.

0.5.3 #

  • Add null check to generated builder "replace" methods.
  • Fail with error on abstract enum classes.
  • Update to build 0.7.0 , build_runner 0.3.0, and build_test 0.4.0.

0.5.2 #

  • Support "import ... as" for field types.

0.5.1 #

  • Add @memoized. Annotate getters on built_value classes with @memoized to memoize their result. That means it's computed on first access then stored in the instance.
  • Support generics, in value types and in serialization.
  • Add support for "standard" JSON via StandardJsonPlugin.

0.5.0 #

  • Update dependency on analyzer, build, quiver.
  • Breaking change: your build.dart and watch.dart now need to import build_runner/build_runner.dart instead of build/build.dart.

0.4.3 #

  • Fix builder getters to be available before a set is used.

0.4.2 #

  • Fix lints.
  • Allow "updates" in value type factory to have explicit void return type.

0.4.1 #

  • Fix some analyzer hints.
  • Fix exception from serializer generator if builder field is incorrect.

0.4.0 #

  • Add benchmark for updating deeply nested data structures.
  • Make builders copy lazily. This makes updates to deeply nested structures much faster: only the classes on the path to the update are copied, instead of the entire tree.
  • Breaking change: if you hand-code the builder then you must mark the fields @virtual so they can be overriden in the generated code.
  • Auto-create nested nullable builders when they're accessed. Fixes deserialization with nested nullable builder.

0.3.0 #

  • Merged built_json and built_json_generator into built_value and built_value_generator. These are intended to be used together, and make more sense as a single package.
  • Fix generation when class extends multiple interfaces.
  • Add serialization of BuiltListMultimap and BuiltSetMultimap.

0.2.0 #

  • Merged enum_class and enum_class_generator into built_value and built_value_generator. These are intended to be used together, and make more sense as a single package.
