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.

v14.0.1

• Fix bug with nullable types in ObjCBlock's type arguments:
  https://github.com/dart-lang/native/issues/15371537
• Fix a path normalization bug: https://github.com/dart-lang/native/issues/1543

v14.0.0

• Create a public facing API for ffigen that can be invoked as a library:
  void generate(Config config). Make Config an implementatble interface,
  rather than needing to be parsed from yaml.
• Add a external-versions config option. Setting the minimum target
  version will omit APIs from the generated bindings if they were deprecated
  before this version.
• Global variables using ObjC types (interfaces or blocks) will now use the
  correct Dart wrapper types, instead of the raw C-style pointers.
• Rename assetId under ffi-native to asset-id to follow dash-case.
• Breaking change: ObjC blocks are now passed through all ObjC APIs as
  ObjCBlock<Ret Function(Args...)>, instead of the codegenned
  ObjCBlock_... wrapper. The wrapper is now a non-constructible set of util
  methods for constructing ObjCBlock.
• Breaking change: Generated ObjC code has been migrated to ARC (Automatic
  Reference Counting), and must now be compiled with ARC enabled. For example,
  if you had a line like s.requires_arc = [] in your podspec, this should
  either be removed, or you should add the ffigen generated ObjC code to the
  list. If you're compiling directly with clang, add the -fobjc-arc flag.
• Breaking change: Structs with enum members now generate their members
  as Dart enum values as well. For example, with an enum MyEnum and a struct
  with a member MyEnum enumMember, two members are generated: enumMemberAsInt
  which contains the original integer value, and enumMember, which is of type
  MyEnum. If you configure the enum to be generated as Dart integers, this
  new behavior will not apply, and the struct member will be an integer as well.
• Breaking change: Enums generated as integers will now generate sealed
  classes as opposed to abstract classes.
• Fix some bugs in the way ObjC method families and ownership annotations were
  being handlhttps://github.com/dart-lang/native/issues/14461446
• Apply the existing member-rename option to ObjC interface and protocol
  methods and properties.
• Add a member-filter option that filters ObjC interface and protocol methods
  and properties.

v13.0.0

• Breaking change: Code-gen the ObjC id type to ObjCObjectBase rather
  than NSObject, since not all ObjC classes inherit from NSObject. Eg
  NSProxy.
• Breaking change: Generate a native trampoline for each listener block, to
  fix a ref counting bhttps://github.com/dart-lang/native/issues/835/835.
  • If you have listener blocks affected by this ref count bug, a .m file will
    be generated containing the trampoline. You must compile this .m file into
    your package. If you already have a flutter plugin or build.dart, you can
    simply add this generated file to that build.
  • If you don't use listener blocks, you can ignore the .m file.
  • You can choose where the generated .m file is placed with the
    output.objc-bindings config option.
• Breaking change: Native enums are now generated as real Dart enums, instead
  of abstract classes with integer constants. Native enum members with the same
  integer values are handled properly on the Dart side, and native functions
  that use enums in their signatures now accept the generated enums on the Dart
  side, instead of integer values. To opt out of this, use the enums->as-int
  option as specified in the README.
• Breaking change: Enum integer types are implementation-defined and not
  part of the ABI. Therefore FFIgen does a best-effort approach trying to mimic
  the most common compilers for the various OS and architecture combinations.
  To silence the warning set config silence-enum-warning to true.
• Rename ObjC interface methods that clash with type names. Fixes
  https://github.com/dart-lang/native/issues/10071007.
• Added support for implementing ObjC protocols from Dart. Use the
  objc-protocols config option to generate bindings for a protocol.
• Fix some bugs where ObjC interface/protocol methods could collide with Dart
  built-in methods, or with types declared elsewhere in the generated bindings.
• Add include-unused-typedefs to allow generating typedefs that are not
  referred to anywhere, the default option is false.
• Use package:dart_flutter_team_lints.

v12.0.0

• Global variables are now compatible with the ffi-native option.
• Exposing symbol addresses of functions and globals is now compatible with the
  ffi-native option.
• Add retainAndReturnPointer method to ObjC objects and blocks, and add
  castFromPointer method to blocks.
• Add -Wno-nullability-completeness as default compiler option for MacOS.
• Breaking change: Use package:objective_c in ObjC bindings.
  • ObjC packages will have a flutter dependency (until
    https://github.com/dart-lang/native/issues/1068ues/1068 is fixed).
  • Core classes such as NSString have been moved into package:objective_c.
  • ObjC class methods don't need the ubiquitous lib argument anymore. In
    fact, ffigen won't even generate the native library class (unless it needs
    to bind top level functions without using @Native). It is still necessary
    to DynamicLibrary.open the dylib though, to load the classes and methods.
  • Adapting to this change:
    • Update ffigen and re-run the code generation. If the generated code no
      longer contains the native library class, it means it isn't needed
      anymore. So final lib = FooNativeLib(DynamicLibrary.open('foo.dylib'));
      must be changed to DynamicLibrary.open('foo.dylib');.
    • Regardless of whether the native library class still exists, delete the
      lib parameter from all ObjC object constructors and static method calls
      and block constructors.
    • If core ObjC classes such as NSString are being used,
      package:objective_c must be imported, as they won't be exported by the
      generated bindings.
• Add --[no-]format option to ffigen command line, which controls whether the
  formatting step happens. Defaults to true.
• Delete Dart functions associated with ObjC closure blocks when the block is
  destroyed. Fihttps://github.com/dart-lang/native/issues/204/204
• Reduce cursor definition not found logs when structs/unions ->
  dependency-only is set to opaque.

v11.0.0

Compare Source

• Any compiler errors/warnings in source header files will now result in
  bindings to not be generated by default, since it may result in invalid
  bindings if the compiler makes a wrong guess. A flag --ignore-source-errors (or yaml config ignore-source-errors: true)
  must be passed to change this behaviour.
• Breaking change: Stop generating setters for global variables marked const in C.
• Fix objc_msgSend being used on arm64 platforms where it's not available.
• Fix missing comma with ffi-native functions marked leaf.
• Add support for finding libclang in Conda environment.

v10.0.0

Compare Source

• Stable release targeting Dart 3.2 using new dart:ffi features available
  in Dart 3.2 and later.
• Add support for ObjC Blocks that can be invoked from any thread, using
  NativeCallable.listener.
• Fix invalid exceptional return value ObjCBlocks that return floats.
• Fix return_of_invalid_type analysis error for ObjCBlocks.
• Fix crash in ObjC methods and blocks that return structs by value.
• Fix ObjC methods returning instancetype having the wrong type in sublasses.
• When generating typedefs for Pointer<NativeFunction<Function>>, also
  generate a typedef for the Function.
• Use Dart wrapper types in args and returns of ObjCBlocks.
• Use Dart wrapper types in args and returns of static functions.
• Renamed asset to assetId for ffi-native.

⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: crates/ui/pubspec.lock

Command failed: flutter pub upgrade ffigen
The current Dart SDK version is 3.3.0.

Because mizer depends on ffigen >=15.0.0 which requires SDK version >=3.4.0 <4.0.0, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on ffigen: flutter pub add dev:ffigen:^8.0.2
