It uses the [audioplayer](https://pub.dartlang.org/packages/audioplayer#-readme-tab-) plugin to play files, and [path_provider](https://pub.dartlang.org/packages/path_provider#-readme-tab-) to locate the external directory and search it for playable files. Metadata is gathered through native java code. I also used this [Waves widget](https://github.com/i-protoss/wave).
