Release Notes

dart-lang/native (ffigen)

v16.0.0

• Ensure all protocols referenced in bindings are available at runtime.
• Use package:dart_style directly to format generated Dart code, rather than
  subprocessing to dart format.
• Use package:objective_c 4.0.0
• Fix various small bugs todo with config filters:
  • https://github.com/dart-lang/native/issues/1582
  • https://github.com/dart-lang/native/issues/1594
  • https://github.com/dart-lang/native/issues/1595
• Fix a bug where nullable
  typealiases were treated as non-null.
• Allow static and instance methods to have the same name:
  https://github.com/dart-lang/native/issues/11361136
• Breaking change: Change the way ObjC categories are generated. Instead of
  inserting their methods into the interface, generate Dart extension methods.
  For instance methods this makes no difference to user code (as long as the
  extension methods are imported correctly). But for static methods it means
  MyInterface.staticMethod must change to MyCategory.staticMethod.
  Categories are included/excluded by the objc-categories config entry.
• Add include-transitive-objc-interfaces, include-transitive-objc-protocols,
  and include-transitive-objc-categories config flags, which control whether
  transitively included ObjC interfaces, protocols, and categories are
  generated.
• Breaking change: include-transitive-objc-interfaces defaults to false,
  which changes the default behavior from pulling in all transitive deps, to
  generating them as stubs. include-transitive-objc-protocols defaults to
  false, and include-transitive-objc-categories defaults to true, but these
  both replicate the existing behavior.
• Fix bugs caused by
  mismatches between ObjC and Dart's inheritance rules.

v15.0.0

• Bump minimum Dart version to 3.4.
• Dedupe ObjCBlock trampolines to reduce generated ObjC code.
• Update to latest package:objective_c.
• ObjC objects now include the methods from the protocols they implement. Both
  required and optional methods are included. Optional methods will throw an
  exception if the method isn't implemented.
• Breaking change: Only generate ObjC protocol implementation bindings for
  protocols that are included by the config filters. This is breaking because
  previously super protocols would automatically get implementation bindings,
  rather than just being incorporated into the child protocol. If you want those
  implementation bindings, you may need to add the super protocol to your
  objc-protocols filters.
• Fix a bug where ObjC listener blocks could be deleted after being invoked by
  ObjC but before the invocation was received by Dahttps://github.com/dart-lang/native/issues/1571ues/1571
• sort: config option now affects ObjC interface/protocol methods.
• Fix a bug where NSRange was not being imported from package:objective_c:
  https://github.com/dart-lang/native/issues/11801180
• Breaking change: Return structs from ObjC methods by value instead of
  taking a struct return pointer.
