Flutter web: uncaught exception for getTemporaryDirectory (path_provider) when using just_audio

I'm using the new experimental LockCachingAudioSource with just_audio. It seems to work on Android and iOS but when I run my app on the web I get the following uncaught error:

Error: MissingPluginException(No implementation found for method getTemporaryDirectory on channel plugins.flutter.io/path_provider)
    at Object.throw_ [as throw] (http://localhost:49168/dart_sdk.js:5041:11)

Here is my code:

_playlist = ConcatenatingAudioSource(
  children: mediaItemList
      .where((item) => item.extras?['url'] is String)
      .map((item) {
    final String url = item.extras?['url'];
    return LockCachingAudioSource(Uri.parse(url));
  }).toList(),
);
await _player.setAudioSource(_playlist);

I found a solution so I am posting it below.

Currently just_audio doesn't support LockCachingAudioSource on the web. The solution is to use one of the supported AudioSources when running on on the web:

if (kIsWeb) {
  return AudioSource.uri(Uri.parse(url));
}
return LockCachingAudioSource(Uri.parse(url));
