Experimental binding generator for FFI bindings.
For some header file example.h:
int sum(int a, int b);
Add configurations to Pubspec File:
ffigen: output: 'generated_bindings.dart' headers: - 'example.h'
Output (generated_bindings.dart).
DynamicLibrary _dylib; /// Initialises dynamic library void init(DynamicLibrary dylib) { _dylib = dylib; } int sum(int a,int b) { return _sum(a,b); } final _dart_sum _sum = _dylib.lookupFunction<_c_sum, _dart_sum>('sum'); typedef _c_sum = Int32 Function(Int32 a,Int32 b); typedef _dart_sum = int Function(int a,int b);

(or directly under a seperate yaml file which when u specify it passing --config filename
when running the tool)pub run ffigen
.A dynamic library for a wrapper to libclang needs to be generated as it is used by the parser submodule.
sudo apt-get install libclang-dev
.cd tool/wrapped_libclang
, then run dart build.dart
.cd tool\wrapped_libclang
, then run dart build.dart
.cd tool/wrapped_libclang
, then run dart build.dart
.cd examples/<example_u_want_to_run>
, Run pub get
.pub run ffigen
.Dynamic library for some tests need to be built before running the examples.
cd test/native_functions_test
.dart build_test_dylib.dart
.Run tests from the root of the package with pub run test
