pigeon 1.0.1

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

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.

0.1.24

• Moved logic from bin/ to lib/ to help customers wrap up the behavior.
• Added some more linter ignores for Dart.

0.1.23

• More Java linter and linter fixes.

0.1.22

• Java code generator enhancements:
  • 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

• Null safe requires Dart 2.12.

0.1.17

• Split out test code generation for Dart into a separate file via the --dart_test_out flag.

0.1.16

• Fixed running in certain environments where NNBD is enabled by default.

0.1.15

• Added support for running in versions of Dart that support NNBD.

0.1.14

• [Windows] Fixed executing from drives other than C:.

0.1.13

• Fixed execution on Windows with certain setups where Dart didn't allow backslashes in import statements.

0.1.12

• Fixed assert failure with creating a PlatformException as a result of an exception in Java handlers.

0.1.11

• Added flag to generate null safety annotated Dart code --dart_null_safety.
• Made it so Dart API setup methods can take null.

0.1.10+1

• Updated the examples page.

0.1.10

• Fixed bug that prevented running pigeon on Windows (introduced in 0.1.8).

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

• Fixed unused variable linter warning in Dart code under certain conditions.

0.1.5

• Made array datatypes correctly get imported and exported avoiding the need to add extra imports to generated code.

0.1.4

• Fixed nullability for NSError's in generated objc code.
• Fixed nullability of nested objects in the Dart generator.
• Added test to make sure the pigeon version is correct in generated code headers.

0.1.3

• Added error message if supported datatypes are used as arguments or return types directly, without an enclosing class.
• Added support for List and Map datatypes in Java and Objective-C targets.

0.1.2+1

• Updated the Readme.md.

0.1.2

• Removed static analysis warnings from generated Java code.

0.1.1

• Fixed issue where nested types didn't work if they weren't present in the Api.

0.1.0

• Added pigeon.dart.
• Fixed some Obj-C linter problems.
• Added the ability to generate a mock handler in Dart.
