ProgressiveAudioSource class Null safety

An AudioSource representing a regular media file such as an MP3 or M4A file. The following URI schemes are supported:

  • file: loads from a local file (provided you give your app permission to access that file).
  • asset: loads from a Flutter asset (not supported on Web).
  • http(s): loads from an HTTP(S) resource.

On platforms except for the web, the supplied headers will be passed with the HTTP(S) request.

If headers are set, just_audio will create a cleartext local HTTP proxy on your device to forward HTTP requests with headers included.
