CHANGELOG.md

10.0.0-dev.0

• 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.
• Bump min SDK version to 3.2.0-210.4.beta.
• Renamed asset to assetId for ffi-native.

9.0.1

• Fix doc comment missing on struct/union array fields.
• Allow extern inline functions to be generated.

9.0.0

• Added a JSON schema for FFIgen config files.

8.0.2

• Fixed invalid code generated due to zero-length arrays in structs/union.

8.0.1

• Fixed invalid code generated due to anonymous structs/unions with unsupported types.

8.0.0

• Stable release for Dart 3.0 with support for class modifers, variadic arguments, and @Natives.

8.0.0-dev.3

• Added support for variadic functions using config functions -> variadic-arguments.

8.0.0-dev.2

• Use @Native syntax instead of deprecated @FfiNative syntax.

8.0.0-dev.1

• Fix invalid struct/enum member references due to multiple anonymous struct/enum in a declaration.

8.0.0-dev.0

• Adds final class modifier to generated sub types Struct, Union and Opaque. A class modifier is required in Dart 3.0 because the classes dart:ffi as marked base. When migrating a package that uses FFIgen, and exposes the generated code in the public API of the package, to Dart 3.0, that package does not need a major version bump. Sub typing Struct, Union and Opaque sub types is already disallowed by dart:ffi pre 3.0, so adding the final keyword is not a breaking change.
• Bumps SDK lowerbound to 3.0.
