flutter_silk #

A flutter ffi plugin for converting audio from silk to pcm/mp3. Support Macos, Ios, Linux, Windows and Android.

Usage #

final silkData = File("input.silk").readAsBytesSync();
var output = silkToMp3(silkData);
File("output.mp3").writeAsBytesSync(output!);

For a complete example, please go to /example folder.

Project structure #

This template uses the following structure:

  • src: Contains the native source code, and a CmakeFile.txt file for building that source code into a dynamic library.

  • lib: Contains the Dart code that defines the API of the plugin, and which calls into the native code using dart:ffi.

  • platform folders (android, ios, windows, etc.): Contains the build files for building and bundling the native code library with the platform application.

Binding to native code #

To use the native code, bindings in Dart are needed. To avoid writing these by hand, they are generated from the header file (src/flutter_silk.h) by package:ffigen. Regenerate the bindings by running flutter pub run ffigen --config ffigen.yaml.

Invoking native code #

Very native functions can be directly invoked from any isolate. For example, see silkToPcm pcmToMp3 silkToMp3 in lib/flutter_silk.dart.
