Sounds provide a complete api and Widgets for audio playback and recording. Both iOS and Android are supported.

Sounds #

Sounds is a fork of the Flutter Sound project.

Sounds is almost a complete rewrite of the dart code from Flutter Sound. The aim of the rewrite has been resolve a number of issues apparent in Flutter Sound:

  • jank during playback.
  • crashes due to threading issues.
  • redesign the api so it is clean and consistent.
  • design an api that will accomodate future expansion of the core feature set.
  • provide additional features.
  • Hide internal apis from the public api.
  • Provide a consistent error handling mechanisim via exceptions.
  • Remove duplicated code.
  • Bring the code in line with Google's recommended best practices.
