| # mini_audio |
| |
| This project is a minimal, cross-platform demonstration of how to use Dart's |
| [build hooks][], with code assets and `dart:ffi` to call a simple function from |
| a popular C library. This project uses the `miniaudio` library to play audio |
| files. |
| |
| [build hooks]: https://dart.dev/tools/hooks |
| |
| ## How it works |
| |
| The native code is built by the [`hook/build.dart`](hook/build.dart), which is |
| run by the Dart SDK CLI tools. This build hook compiles the C code from |
| [`third_party/miniaudio.c`](third_party/miniaudio.c) into a dynamic library. |
| |
| The Dart FFI bindings to the C code are generated by |
| [`tool/ffigen.dart`](tool/ffigen.dart). FFIgen generates Dart FFI bindings from |
| [`third_party/miniaudio.h`](third_party/miniaudio.h) into |
| [`lib/src/third_party/miniaudio.g.dart`](lib/src/third_party/miniaudio.g.dart). |
| |
| The Dart code in [`lib/src/mini_audio.dart`](lib/src/mini_audio.dart) uses the |
| generated FFI bindings to provide a Dart API (not exposing any C types). |
