The code below is no longer valid from audioplayers v1.0.1

final player = AudioCache();
player.play('note1.wave');

Instead U can do this

final player = AudioPlayer();
//
player.play(UrlSource('note1.wave'));

// If file located in assets folder like assets/sounds/note01.wave"
await player.play(AssetSource('sounds/note1.wave'));

consider look in migration guide from audioplayers

There seems to be the issue with your import. Do import this

import 'package:audioplayers/audioplayers.dart';

If the issue still exists, then use an older version of it. I think version 0.19.0 should work for you.

@Raj if You are doing LinkedIn course by London App Brewery and Angela Yu then an exact version that would work perfectly would be 0.10.0

audioplayers: 0.10.0

It's the one used by Angela and it worked perfectly for me :-) Wouldn't try it though if not for @Zain Basharat Ali advice. Thanks for Your tip! :-)

AudioCache is dead because of confusion in name. Now, if you want to play an audio file from assets you can use this.

// add this in imports
import 'package:audioplayers/audioplayers.dart';

// play audio
final player = AudioPlayer();
player.play(AssetSource('note1.wav'));

Use this instead of AssetSource if you want don't want to play from assets.

  1. UrlSource: get the audio from a remote URL from the Internet
  2. DeviceFileSource: access a file in the user's device, probably selected by a file picker
  3. AssetSource: play an asset bundled with your app, normally within the assets directory
  4. BytesSource (only some platforms): pass in the bytes of your audio directly (read it from anywhere).

You can see more from audioplayers documentation
