ffigen changelog | Dart package

11.0.0 #

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.

10.0.0 #

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.

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.

Fix typedef include/exclude config.
Return ObjCBlock wrapper instead of raw pointer in more cases.

Fix bug where function bindings were not deduped correctly.

6.1.1 #

EXPERIMENTAL support for FfiNative. The API and output might change at any point.

Bump package:ffi to 2.0.1.

6.0.1 #

Replace path separators in include-directives before matching file names.
Add more ways to find libclang.

5.0.1 #

Add a the xcode tools llvm as default path on MacOS.

5.0.0 #

Stable release targeting Dart 2.17, supporting ABI-specific integer types.

Release for Dart SDK >=2.14.

4.0.0-dev.2 #

Added config key functions -> expose-typedefs to expose the typedef to Native and Dart type.
Config key function->symbol-address no longer exposes the typedef to Native type. Use expose-typedefs to get the native type.

4.0.0-dev.1 #

This package now targets package:lints for the generated code. The generated code uses C symbol names as is. Use either // ignore_for_file: lintRule1, lintRule2 in the preamble, or rename the symbols to make package:lints happy.
Name collisions are now resolved by suffixing <int> instead of _<int>.

4.0.0-dev.0 #

Example C Code	Generated Dart typedef
`typedef struct A{ ... } TA, *PA; TA func(PA ptr);`	`class A extends ffi.Struct {...} typedef TA = A; typedef PA = ffi.Pointer<A>; TA func(PA ptr){...}`

All declarations that are excluded by the user are now only included if being used somewhere.
