From where the "PlayerState" class comes in audioPlayers flutter package?

Question

I needed some help regarding using audioplayer package in flutter, i found a piece of code thats understandable except the PlayerState.PLAYING part, is this PlayerState a part of audioPlayers package or what?

Code:

 //listen to states: playing paused stopped
    audioPlayer.onPlayerStateChanged.listen((state){
      setState(() {
        isPlaying = state == PlayerState.PLAYING;
      });
    });

Also if anyone can tell the right way to listen to states using audioPlayers.

Check this official documentation here to get your correct answer. Currently I guess its PlayerState.playing used.
