22.0.0-dev

  • Remove PbEventMixin mixin. (#738)

  • Type of repeated fields is now PbList (instead of List), type of map fields is now PbMap (instead of Map). (#903)

    This change requires protobuf-4.0.0.

21.1.2

  • Fix a bug in comment parsing. (#871, #879)

21.1.1

  • Rename a local variable used with message constructors to avoid potential conflicts with protobuf field names.

21.1.0

  • Generate code comments for annotated protobuf inputs. (#161)

  • Generate message constructor arguments by default again. New flag disable_constructor_args disables generating the arguments.

    Constructor arguments were removed in 21.0.0 as they increase dart2js binary sizes even when the arguments are not used.

    Example usage to disable constructor arguments:

    protoc --dart_out='disable_constructor_args,<other options>:.' ...
    

    (#850, #855)

21.0.2

  • Fix missing protobuf import in generated grpc files. (#844)

21.0.1

(Bad release, retracted)

21.0.0

  • Identifiers fromBuffer, fromJson, $_defaultFor, initByValue are no longer reserved. Proto fields with those Dart names will no longer have a suffix added. (#679)

  • Remove message constructor arguments. Constructors with arguments cause increase in release binary sizes even when no arguments are passed to the constructors. (#703)

    Migration:

    Set the fields after construction, using cascade syntax. For example, if you have:

    MyMessage(a: 123, b: [1, 2, 3])
    

    You can do:

    MyMessage()
      ..a = 123
      ..b.addAll([1, 2, 3])
    
  • Require Dart 2.19.

  • Export public dependencies (import publics in proto files) in .pbenum.dart files, same as .pb.dart files. (9aad6aa)

  • Fix decoding map fields when key or value (or both) fields of a map entry is missing. (#719, #745)

  • Generated files now split ignore_for_file comments across multiple lines when necessary. (#770)

  • Generated files now uses shared consts to eliminate repeated bool.fromEnvironment() expressions. (#772)

  • Removed accidental /// at the top of generated Dart files to avoid new dangling_library_doc_comments lint. (#774)

  • Generated files now have sorted imports and have fewer import-related ignore_for_file: analysis directives. (#778)

  • Remove duplicated consts in generated files. (#773)

20.0.1

  • Fix proto3 repeated field encoding without the packed option (#345, #635)

20.0.0

  • Stable release generating null-safe code.

19.3.1

  • Emit binary coded descriptors, which can be used to reflect over the options given to the descriptor.

19.3.0

  • Generate constructors with optional named arguments for prefilling fields.
  • Output language version 2.7 in generated files to support extension methods.

19.2.1

  • Support optional proto3 fields.

19.2.0+1

  • Fix syntax error introduced by gRPC client interceptor changes.

19.2.0

  • Support client interceptors for gRPC. Requires grpc package 2.8.0 or newer.

19.1.0

  • Emit depreciation of generated copyWith and clone methods.

  • Emit exports of GeneratedMessageGenericExtensions from pb.dart files.

  • Make protobuf enum names dependent on a fromEnvironment constant.

    This will allow configuring the omission of the names in the final build.

    If a target is built with dart_env = {"protobuf.omit_enum_names": "true"} enum names will not be present in the compiled binary.

  • Make message and field names depend on fromEnvironment constants protobuf.omit_message_names and protobuf.omit_field_names respectively.

  • Omit type on a left hand side of generated static fields for extensions, which results in stricter type (Extension<ExtensionType> instead of just Extension).

  • Fix escaping of string default values.

19.0.3-dev

  • Ignore annotate_overrides in generated files.
  • Requires sdk 2.3.0
  • Update pedantic to 1.9.2

19.0.2

  • Fix: escape the special character $ in descriptor's json_name.

19.0.1

  • Fix: avoid naming collisions with Int64 and enum names beginning with digits after an initial underscore.

19.0.0+1

  • Updated protobuf dependency to ‘>=0.14.4 <2.0.0’ to allow 1.0.0.

19.0.0

  • Breaking: Generates code that requires at least protobuf 0.14.4. If protoc_plugin is installed in your path with pub global activate you can upgrade with pub global activate protoc_plugin 19.0.0
    • GeneratedMessage classes now have methods ensureX for each message field X.
    • Add specialized getters for String, int, and bool with usual default values.
    • Annotate generated accessors with the tag number of the associated field.
  • Breaking: Use unmangled names for the string representation of enum values. Mangled names would lead to wrong proto3 json en- and decoding.
  • Annotate generated accessors with the tag number of the associated field.

18.0.3

  • Fix: Allow decoding tagnumbers of up to 29 bits. Would fail before with more than 28 bits.

18.0.2

  • Fix mangling of extension names, message type names, and enum names that are Dart keywords.

    Now you can have an extension called is and an enum called class.

18.0.1

  • Add a bin/protoc-gen-dart.bat script making it easier to compile on windows using a local checkout.

18.0.0

  • Breaking: Generates code that requires at least protobuf 0.14.0.

  • Generate the non-camel-case name of fields when it cannot be derived from the json name.

  • Breaking: Use the correct proto3 Json CamelCase names for the string representation of field names (also for extensions), instead of using the name of the dart identifier for that field.

    In most cases this name coincides with the name have emitted until now and require no change.

    Exceptions are:

    • Fields with a name that was disambiguated to not clash with other dart entities.
    • fields with an explicit json_name option.
    • groups have a different camel-casing scheme.

    For any field with an updated name, this might require changes to uses of GeneratedMessage.getTagNumber(String FieldName), and calls to name-related methods of GeneratedMessage._info.

    GeneratedMessage.toString() also uses the string representation. It will now print the json-name.

  • Well-known types (for now only google.protobuf.Any and google.protobuf.Timestamp) now uses a mixin to add special handling code instead of hardcoding it in the compiler.

17.0.5

  • Remove unnecessary cast from generated grpc stubs.

17.0.4

17.0.3

  • Fix: Copy oneof state when doing GeneratedMessage.copyWith().

17.0.2

  • Fix: Avoiding argument_type_not_assignable and return_of_invalid_type lint warnings.

17.0.1

  • Fix: Actually use prefixed imports from .pbserver, .pb.json, .pbgrpc files.

17.0.0

  • Breaking change: seal protobuf message classes by using an internal private constructor and changing the rest to factories.

16.0.7

  • Always prefix .pb.dart imports in .pbserver, .pb.json, .pbgrpc files.

16.0.6

  • Track the original order of proto fields and include it in metadata to ensure the correct fields are being referenced.

16.0.5

  • Fix generation of invalid Dart code for oneof enums by adding list of reserved enum names.

16.0.4

  • Generate ‘@Deprecated’ annotations on fields that have been deprecated in the corresponding .proto file.

16.0.3

  • Sync Kythe metadata updates from internal repo:
  • Remove the extra 1 (field name) from generated field paths, so they refer to the whole field rather than the name.
  • Add missing proto message field metadata to the Dart proto generator (attached to setter/getter/has/clear methods). Fix a bug with indented space counting, which would cause all indented fields to use the incorrect count (off by the size of the indent)
  • Add metadata to the unnamed constructors in the generated dart proto files. Removed extra list copy constructor calls when the field path isn‘t being modified. The named constructors (e.g. fromJson) don’t need this because, at the call site, the class name and the constructor name are two separate links.

16.0.2

  • Generated files now import ‘dart:core’ with a prefix
  • Add ‘camel_case_types’ to analysis_options and add it in the ‘ignore_for_file’ header of the generated files.

16.0.1

  • Add DateTime conversion methods to google.protobuf.Timestamp.

16.0.0

  • Add ability to generate Kythe metadata files via the generate_kythe_info option.
  • Breaking change: Remove the ‘$checkItem’ function from generated message classes and use the new method ‘pc’ on ‘BuilderInfo’ to add repeated composite fields. Generated files require package:protobuf version 0.13.4 or newer.
  • Breaking change: The generated *.pbgrpc.dart files now import package:grpc/service_api.dart instead of package:grpc/grpc.dart. Generated code needs at least package:grpc 1.0.1.

15.0.3

  • Add test for frozen messages with unknown fields and update protobuf dependency to 0.13.1.

15.0.2

  • The generated pbgrpc.dart files now import package:grpc/grpc.dart with a prefix.

15.0.1

  • Add test for frozen messages with extension fields and update protobuf dependency to 0.13.0.

15.0.0

  • Breaking change: Changed BuilderInfo call for map fields to include the BuilderInfo object for map entries. Generated files require package:protobuf version 0.12.0 or newer.

14.0.1

14.0.0

  • Breaking change: generated message classes now have a new instance method createEmptyInstance that is used to support the new toBuilder() semantics of protobuf 0.11.0. The generated code requires at least protobuf 0.11.0.

13.0.1

  • Add test for recursive merging and update protobuf dependency to 0.10.7.

13.0.0

  • Breaking change: Support for oneof Generated files require package:protobuf version 0.10.6 or newer.

12.0.0

  • Breaking change: Handle identifiers starting with a leading underscore. This covers message names, enum names, enum value identifiers and file names.

    Before, these would appear in the generated Dart code as private identifiers. Now the underscore is moved to the end.

    Field names and extension field names already had all underscores removed, and these are not affected by this change.

    If there is a conflicting name with a trailing underscore defined later in the same scope, a disambiguation will happen that can potentially lead to existing identifiers getting a new name in the generated Dart.

    For example:

    message _Foo {}
    message Foo_ {}
    

    _Foo will get the name Foo_ and Foo_ will now end up being called Foo__.

11.0.0

  • Breaking change: Support for map fields Generated files require package:protobuf version 0.10.5 or newer. Protobuf map fields such as:

    message Foo { map<int32, string> map_field = 1; } are now no longer represented as List<Foo_MapFieldEntry> but as Map<int, String>.

    All code handling these fields needs to be updated.

    Accidentally published as 11.0.0 instead of 0.11.0. Continuing from here.

0.10.5

  • Generated files now import dart:async with a prefix to prevent name collisions.

0.10.4

  • Change the fully qualified message name of generated messages to use BuilderInfo.qualifiedMessageName. Requires package:protobuf version 0.10.4 or newer.

0.10.3

  • Remove runtime as check of enum valueOf by using correctly typed Map of values. Generated files must require package:protobuf version 0.10.3 or newer.

0.10.2

  • Add link to source file in generated code.

0.10.1

  • Prefix generated Dart proto imports by proto file path instead of by package. Tighten up member name checks for generated enum classes.

0.10.0

  • Breaking change: Support for any messages. Generated files require package:protobuf version 0.10.1 or newer. BuilderInfo.messageName will now be the fully qualified name for generated messages.

0.9.0

  • Breaking change: Add copyWith() to message classes and update getDefault() to use freeze(). Requires package:protobuf version 0.10.0 or newer.

0.8.2

  • Generated code now imports ‘package:protobuf/protobuf.dart’ prefixed. This avoids name clashes between user defined message names and the protobuf library.

0.8.1

  • Adjust dependencies to actually be compatible with Dart 2.0 stable.

0.8.0+1

  • Dart SDK upper constraint raised to declare compatibility with Dart 2.0 stable.

0.8.0

  • Breaking change: Generated RpcClient stubs use the generic invoke method. Requires package:protobuf version 0.8.0 or newer.
  • Dart 2 fixes.

0.7.11

  • Dart 2 fix.

0.7.10

  • Small performance tweak for DDC.

0.7.9

  • Add fast getters for common types.
  • Only pass index instead of tag and index in generated code.
  • Fix uses-dynamic-as-bottom error in generated gRPC code.

0.7.8

  • Added enumValues to FieldInfo.

0.7.7

  • Avoid name clashes between import prefix and field names.
  • Avoid name clashes between generated enum and extension class names.
  • Updated gRPC client stub generation to match latest changes to dart-lang/grpc-dart.

0.7.6

  • Updated gRPC client stub generation to produce code matching latest changes to dart-lang/grpc-dart.

0.7.5

  • Use real generic syntax instead of comment-based.
  • Support 2.0.0 dev SDKs.

0.7.4

  • Added call options to gRPC client stubs.

0.7.3

gRPC support

  • Added gRPC stub generation.
  • Updated descriptor.proto from google/protobuf v3.3.0.

0.7.2

  • Added CHANGELOG.md

0.7.1

  • Enable executable for pub global usage. Protoc plugin can now be installed by running pub global activate protoc_plugin.
  • Ensure generated extension class names don't conflict with message class names.
  • Function will soon be a reserved keyword, so don't generate classes with that name.
  • Strong mode tweaks and lint fixes.

0.7.0 - Not released

  • Change how to customize the Dart name of a field to using a dart_name option.
  • Implemented support for adding external mixins to generate Dart protos.

0.6.0+1 - Not released

  • Fix missing import when an extension uses an enum in the same .proto file.

0.6.0 - Not released

  • Move protobuf enums to a separate .pbenum.dart file.
  • Move server-side stubs to .pbserver.dart.

0.5.2 - Not released

  • Generate separate .pbjson.dart files for constants.

0.5.1

Strong mode and Bazel

  • Fixed all analyzer diagnostics in strong mode.
  • Added experimental support for Bazel.

0.5.0

Performance improvements

This release requires 0.5.0 of the protobuf library.

  • significantly improved performance for getters, setters, and hazzers
  • Each enum type now has a $json constant that contains its metadata.

0.4.1

Fixed imports, $checkItem, $json

  • Fixed all warnings, including in generated code.
  • Started generating $checkItem function for verifying the values of repeated fields
  • Fixed service stubs to work when a message is in a different package
  • Started generating JSON constants to get the original descriptor data for services

0.4.0

Getters for message fields changed

This release changes how getters work for message fields, to detect a common mistake.

Previously, the protobuf API didn't report any error for an incorrect usage of setters. For example, if field “foo” is a message field of type Foo, this code would silently have no effect:

var msg = new SomeMessage(); msg.foo.bar = 123; This is because “msg.foo” would call “new Foo()” and return it without saving it.

The example can be fixed like this:

var msg = new SomeMessage(); msg.foo = new Foo(); msg.foo.bar = 123; Or equivalently:

var msg = new SomeMessage() ..foo = (new Foo()..bar = 123); Starting in 0.4.0, the default value of “msg.foo” is an immutable instance of Foo. You can read the default value of a field the same as before, but writes will throw UnsupportedError.

0.3.11

  • Fixes issues with reserved names

0.3.10

  • Adds support for generating stubs from service definitions.

0.3.9

  • Modify dart_options support so that it supports alternate mixins.
  • Move the experimental map implementation to PbMapMixin

For now, new mixins can only be added using a patch:

  • add the new class to the protobuf library
  • add the class to the list in mixin.dart.

0.3.8

Added option for experimental map API

  • Changed the Map API so that operator [] and operator []= support dotted keys such as “foo.bar”.

This new API is subject to change without notice, but if you want to try it out anyway, see the unit test.

0.3.7 - Unreleased

Added option for experimental map API

  • Added an option to have GeneratedMessage subclasses implement Map.

0.3.6

Added writeToJsonMap and mergeFromJsonMap to reservedNames

The 0.3.6 version of the dart-protobuf library added two new functions, so this release changes the protobuf compiler to avoid using them.

0.3.5

Protobuf changes for smaller dart2js code, Int64 fixes

This change is paired with https://chromiumcodereview.appspot.com/814213003

Reduces code size for one app by 0.9%

  1. Allow constants for the default value to avoid many trivial closures.
  2. Generate and use static M.create() and M.createRepeated() methods on message classes M to ensure there is a shared copy of these closures rather than one copy per use.
  3. Parse Int64 values rather than generate from ‘int’ to ensure no truncation errors in JavaScript.

0.3.4

Parameterize uri resolution and parsing of options, use package:path.

This helps make the compiler more configurable to embed it in other systems (like pub transformers)

0.3.3

Update the version number
