Flutter audioplayers error (1, -19) - No audio is played and the app doesn't crash

I am trying to use the flutter audioplayers package to play audio files and am getting this error. While following an online flutter tutorial I had this exact code and it ran and produced sound correctly, but now it doesn't play audio. I think maybe there is a change in my IDE settings or a change on my computer, but I don't know how to find the issue.

E/MediaPlayerNative(13949): error (1, -19)
E/MediaPlayer(13949): Error (1,-19)
E/MediaPlayerNative(13949): stop called in state 0, mPlayer(0xb4e843c0)

Here is the code I'm using to test the audioplayers package.

import 'package:flutter/material.dart';
import 'package:audioplayers/audio_cache.dart';

void main() => runApp(XylophoneApp());

class XylophoneApp extends StatelessWidget {
  final player = AudioCache();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SafeArea(
          child: Center(
            child: FlatButton(
              color: Colors.red,
              onPressed: () {
                player.play('note1.wav');
              },
              child: Text('Click Me'),
            ),
          ),
        ),
      ),
    );
  }
}

AudioPlayer audioPlayer;
AudioCache audioCache = AudioCache();
String url = 'images/PID_meditation_demo_novoice.mp3';    //local mp3 file in asset folder

playLocal() async {
audioPlayer = await audioCache.play(url);      //audio play function
}

pauseAudio() async {                 // audio pause
await audioPlayer.pause();}

resumeAudio() async {
await audioPlayer.resume();                 //audio resume

}

stopAudio() async {
if(audioPlayer !=null){
await audioPlayer.stop();             //audio srope
}
}
