pigeon 3.2.3

Code generator tool to make communication between Flutter and the host platform type-safe and easier.

3.2.3

• Adds unnecessary_import to linter ignore list in generated dart tests.

3.2.2

• Adds unnecessary_import to linter ignore list for package:flutter/foundation.dart.

3.2.1

• Removes @dart = 2.12 from generated Dart code.

3.2.0

• Adds experimental support for Swift generation.

3.1.7

• [java] Adds option to add javax.annotation.Generated annotation.

3.1.6

• Supports newer versions of analyzer.

3.1.5

• Fixes potential crash bug when using a nullable nested type that has nonnull fields in ObjC.

3.1.4

• [c++] Adds support for non-nullable fields, and fixes some issues with nullable fields. The types of some getters and setter have changed, so this may require updates to existing code.

3.1.3

• Adds support for enums in arguments to methods for HostApis.

3.1.2

• [c++] Fixes minor style issues in generated code. This includes the naming of generated methods and arguments, so will require updates to existing code.

3.1.1

• Updates for non-nullable bindings.

3.1.0

• [c++] Adds C++ code generator.

3.0.4

• [objc] Simplified some code output, including avoiding Xcode warnings about using NSNumber* directly as boolean value.
• [tests] Moved test script to enable CI.

3.0.3

• Adds ability for generators to do AST validation. This can help generators without complete implementations to report gaps in coverage.

3.0.2

• Fixes non-nullable classes and enums as fields.
• Fixes nullable collections as return types.

3.0.1

• Enables NNBD for the Pigeon tool itself.
• [tests] Updates legacy Dart commands.

3.0.0

• BREAKING CHANGE: Removes the --dart_null_safety flag. Generated Dart now always uses nullability annotations, and thus requires Dart 2.12 or later.

2.0.4

• Fixes bug where Dart FlutterApis would assert that a nullable argument was nonnull.

2.0.3

• Makes the generated Java Builder class final.

2.0.2

• Fixes Java crash for nullable nested type.

2.0.1

• Adds support for TaskQueues for serial background execution.

2.0.0

• Implements nullable parameters.
• BREAKING CHANGE - Nonnull parameters to async methods on HostApis for ObjC now have the proper nullability hints.

1.0.19

• Implements nullable return types.

1.0.18

• [front-end] Fix error caused by parsing copyrightHeaders passed to options in @ConfigurePigeon.

1.0.17

• [objc] Factors out helper function for reading from NSDictionary's.
• [objc] Renames static variables to match Google style.

1.0.16

• Updates behavior of run_tests.dart with no arguments.
• [debugging] Adds ast_out to help with debugging the compiler front-end.
• [front-end, dart] Adds support for non-null fields in data classes in the front-end parser and the Dart generator (unsupported languages ignore the designation currently).
• [front-end, dart, objc, java] Adds support for non-null fields in data classes.

1.0.15

• [java] Fix too little information when having an exception

1.0.14

• [tests] Port several generator tests to run in Dart over bash

1.0.13

• [style] Fixes new style rules for Dart analyzer.

1.0.12

• [java] Fixes enum support for null values.

1.0.11

• [ci] Starts transition to a Dart test runner, adds windows support.
• [front-end] Starts issuing an error if enums are used in type arguments.
• [front-end] Passes through all enums, referenced or not so they can be used as a work around for direct enum support.

1.0.10

• [front-end] Made sure that explicit use of Object actually creates the codec that can represent custom classes.

1.0.9

• [dart] Fixed cast exception that can happen with primitive data types with type arguments in FlutterApi's.

1.0.8

• [front-end] Started accepting explicit Object references in type arguments.
• [codecs] Fixed nuisance where duplicate entries could show up in custom codecs.

1.0.7

• [front-end] Fixed bug where nested classes' type arguments aren't included in the output (generated class and codec).

1.0.6

• Updated example README for set up steps.

1.0.5

• [java] Fixed bug when using Integer arguments to methods declared with 'int' arguments.

1.0.4

• [front-end] Fixed bug where codecs weren't generating support for types that only show up in type arguments.

1.0.3

• [objc] Updated assert message for incomplete implementations of protocols.

1.0.2

• [java] Made it so @async handlers in @HostApi() can report errors explicitly.

1.0.1

• [front-end] Fixed bug where classes only referenced as type arguments for generics weren't being generated.

1.0.0

• Started allowing primitive data types as arguments and return types.
• Generics support.
• Support for functions with more than one argument.
• [command-line] Added one_language flag for allowing Pigeon to only generate code for one platform.
• [command-line] Added the optional sdkPath parameter for specifying Dart SDK path.
• [dart] Fixed copyright headers for Dart test output.
• [front-end] Added more errors for incorrect usage of Pigeon (previously they were just ignored).
• [generators] Moved Pigeon to using a custom codec which allows collection types to contain custom classes.
• [java] Fixed NPE in Java generated code for nested types.
• [objc] BREAKING CHANGE: logic for generating Objective-C selectors has changed. void add(Input value) will now translate to -(void)addValue:(Input*)value, methods with no arguments will translate to ...WithError: or ...WithCompletion:.
• [objc] Added @ObjCSelector for specifying custom objc selectors.

0.3.0

• Updated the front-end parser to use dart analyzer instead of dart:mirrors. dart:mirrors doesn't support null-safe code so there were a class of features we couldn't implement without this migration.
• BREAKING CHANGE - the configurePigeon function has been migrated to a @ConfigurePigeon annotation. See ./pigeons/message.dart for an example. The annotation can be attached to anything in the file to take effect.
• BREAKING CHANGE - Now Pigeon files must be in one file per invocation of Pigeon. For example, the classes your APIs use must be in the same file as your APIs. If your Pigeon file imports another source file, it won't actually import it.

0.2.4

• bugfix in front-end parser for recursively referenced datatypes.

0.2.3

• bugfix in iOS async handlers of functions with no arguments.

0.2.2

• Added support for enums.

0.2.1

• Java: Fixed issue where multiple async HostApis can generate multiple Result interfaces.
• Dart: Made it so you can specify the BinaryMessenger of the generated APIs.

0.2.0

• BREAKING CHANGE - Pigeon files must be null-safe now. That means the fields inside of the classes must be declared nullable ( non-null fields aren't yet supported). Migration example:

// Version 0.1.x
class Foo {
  int bar;
  String baz;
}

// Version 0.2.x
class Foo {
  int? bar;
  String? baz;
}

• BREAKING CHANGE - The default output from Pigeon is now null-safe. If you want non-null-safe code you must provide the --no-dart_null_safety flag.
• The Pigeon source code is now null-safe.
• Fixed niladic non-value returning async functions in the Java generator.
• Made runCommandLine return an the status code.

  • Added linter tests to CI.
  • Fixed some linter issues in the Java code.

0.1.21

• Fixed decode method on generated Flutter classes that use null-safety and have null values.

0.1.20

• Implemented @async HostApi's for iOS.
• Fixed async FlutterApi methods with void return.

0.1.19

• Fixed a bug introduced in 0.1.17 where methods without arguments were no longer being called.

0.1.18

0.1.9

• Fixed bug where executing pigeon without arguments would crash (introduced in 0.1.8).

0.1.8

• Started spawning pigeon_lib in an isolate instead of a subprocess. The subprocess could have lead to errors if the dart version on $PATH didn't match the one that comes with flutter.

0.1.7

• Fixed Dart compilation for later versions that support null safety, opting out of it for now.
• Fixed nested types in the Java runtime.

0.1.6
