Assets is being loaded in cache but not found for AudioPlayer - flutter

Question

I'm using the package: audioplayers: ^1.0.1
I'm trying to follow the migration guide of audioplayers found in this link: https://github.com/bluefireteam/audioplayers/blob/main/migration_guide.md
But I can't make it to work.
Here's my pubspec
flutter:
assets:
- assets/sounds/
If I do it like this, it can't load the assets.
final playerSound = AudioPlayer();
await playerSound.setSource(AssetSource('assets/sounds/Pop (1).wav'));
Unhandled Exception: Unable to load asset: assets/assets/sounds/Pop (1).wav
But if I remove the assets, it is trying to find in the cache. I don't get why it is working. Please help to clarify. Thanks!
final playerSound = AudioPlayer();
await playerSound.setSource(AssetSource('sounds/Pop (1).wav'));
java.io.FileNotFoundException: /data/user/0/com.MyName.MyApp/cache/sounds/Pop%20(1).wav: open failed: ENOENT (No such file or directory)

Ok so what i see from the package structure.
If you Go into the AssetSource class which looks as follows :
source.dart file
/// Source representing the path of an application asset in your Flutter
/// "assets" folder.
/// Note that a prefix might be applied by your [AudioPlayer]'s audio cache
/// instance.
class AssetSource extends Source {
final String path;
AssetSource(this.path);
#override
Future<void> setOnPlayer(AudioPlayer player) {
return player.setSourceAsset(path);
}
}
Here if you go inside the setSourceAsset method :
/// Sets the URL to an asset in your Flutter application.
/// The global instance of AudioCache will be used by default.
///
/// The resources will start being fetched or buffered as soon as you call
/// this method.
Future<void> setSourceAsset(String path) async {
final url = await audioCache.load(path);
return _platform.setSourceUrl(playerId, url.path, isLocal: true);
}
if you see the line
final url = await audioCache.load(path);
so this in this AudioCache class if you see the constructor :
/// This is the path inside your assets folder where your files lie.
///
/// For example, Flame uses the prefix 'assets/audio/'
/// (you must include the final slash!).
/// The default prefix (if not provided) is 'assets/'
/// Your files will be found at <prefix><fileName> (so the trailing slash is
/// crucial).
String prefix;
AudioCache({this.prefix = 'assets/'});
So the prefix is assets added as a default in the constructor. So you don't have to call it every time only the file name followed by the folder if you are adding in any case.
