Generator for FFI bindings, using LibClang to parse C header files.

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 #

  • Added support for generating typedefs (referred typedefs only).
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.
  • Improved struct/union include/exclude. These declarations can now be targetted by their actual name, or if they are unnamed then by the name of the first typedef that refers to them.

3.1.0-dev.1 #

  • Users can now specify exact path to dynamic library in llvm-path.

3.1.0-dev.0 #

  • Added support for generating unions.

3.0.0 #

  • Release for dart sdk >=2.13 (Support for packed structs and inline arrays).

3.0.0-beta.0 #

  • Added support for inline arrays in Structs.
  • Remove config key array-workaround.
  • Remove deprecated key llvm-lib from config, Use llvm-path instead.

2.5.0-beta.1 #

  • Added support for Packed structs. Packed annotations are generated automatically but can be overriden using structs -> pack config.
  • Updated sdk constraints to >=2.13.0-211.6.beta.

2.4.2 #

  • Fix issues due to declarations having duplicate names.
  • Fix name conflict of declaration with ffi library prefix.
  • Fix char not being recognized on platforms where it's unsigned by default.

2.4.1 #

  • Added /usr/lib to default dynamic library location for linux.

2.4.0 #

  • Added new config key llvm-path that accepts a list of path/to/llvm.
  • Deprecated config key llvm-lib.

2.3.0 #

  • Added config key compiler-opts-automatic -> macos -> include-c-standard-library (default: true) to automatically find and add C standard library on macOS.

2.2.5 #

2.2.3 #

2.2.2 #

  • Fixed generation of empty opaque structs due to forward declarations in header files.

2.2.1 #

  • Fixed generation of duplicate constants suffixed with _<int> when using multiple entry points.

2.0.3 #

2.0.1 #

  • Switch to preview release of package:quiver.

2.0.0 #

  • Upgraded all dependencies. package:ffigen now runs with sound null safety.

2.0.0-dev.6 #

  • Added support for Nested structs.

2.0.0-nullsafety.1 #

  • Removed the need for --no-sound-null-safety flag.

2.0.0-nullsafety.0 #

  • Migrated to (unsound) null safety.

1.2.0 #

  • Added support for Dart_Handle from dart_api.h.

  • Added config dart-bool (default: true) to use dart bool instead of int in function parameters and return type.

0.2.3+3 #

  • Wrapper dynamic library version now uses ffigen version from its pubspec.yaml file.

0.2.3+2 #

  • Handle code formatting using dartfmt by finding dart-sdk.

0.2.3+1 #

  • Comments config now has a style and length sub keys - style: doxygen(default) | any, length: brief | full(default), and can be disabled by passing comments: false.

0.1.3 #

  • Handled function arguments - dart keyword name collision
  • Fix travis tests: the dynamic library is created using pub run ffigen:setup before running the tests.

0.1.2 #

  • Fixed wrapper not found error when running pub run ffigen.

0.1.1 #

  • Address pub score: follow dart File conventions, provide documentation, and pass static analysis.

  • Support for Functions, Structs and Enums.
  • Glob support for specifying headers.
  • HeaderFilter - Include/Exclude declarations from specific header files using name matching.
