[just_audio_background] buttons not visible in Android in case of single audio source

[mbenci]

Which API doesn't behave as documented, and how does it misbehave? Using just_audio_background package and in Android platform only, control Buttons previous / play / pause / next that generally appear on the background running player if I reproduce only one audio or a playlist made of only one audio

Minimal reproduction project Provide a link here using one of two options: Modify the just_audio_background/example/lib/main.dart leaving only one audio in playlist then execute it The same problem appears if instead of playlist as AudioSource I set a single AudioSource.uri

To Reproduce (i.e. user steps, not code) Execute just_audio_background/example/lib/main.dart in Android device Start any song from a playlist with one element o ar single AudioSource Drag background running player from the top. You'll notice control buttons are not visible.

Error messages None on the debug console

Expected behavior As in iOS, all buttons must be visible. In particulary in case of single song next buttons must be disabled and play/pause button active.
