Unlike the Dart-C FFI, this repo shows some demo for the Dart-Zig FFI.
Used those versions as of Feb 2024:
- Zig SDK: 0.12.0-dev.2250
- Dart SDK: 3.4.0-00.0.dev (Flutter 3.19.0-0.3.pre)
- Debian Sid
There are 2 different ways:
- Manual FFI (under the src directory)
- Automatic FFI with the ffigen command (under the src-ffigen directory)
To build all the Zig libraries:
# Build the library
$ cd src/library
$ zig build --summary allFor the hello world example:
# Install packages and run the caller
$ cd src/dart/01-hello-world
$ dart pub get
$ dart run hello.dartFor the primitives example:
# Install packages and run the caller
$ cd src/dart/02-primitives
$ dart pub get
$ dart run primitives.dartFor the structs example:
# Install packages and run the caller
$ cd src/dart/03-structs
$ dart pub get
$ dart run structs.dartFor the async example:
# Install packages and run the caller
$ cd src/dart/04-async
$ dart pub get
$ dart run async.dartTo build all the Zig libraries:
# Build the library
$ cd src-ffigen/library
$ zig build --summary allManually update the header files:
$ nv src-ffigen/library/zig-cache/hello.h
$ mv src-ffigen/library/zig-cache/hello.h src-ffigen/dart/01-hello-worldUpdate the pubspec.yaml:
$ nv src-ffigen/app/01-hello-world/pubspec.yamlGenerate the ffi file:
$ cd src-ffigen/app/01-hello-world
$ dart run ffigenRun the demo:
$ dart run hello.dart
