Describe the bug
The plugin works fine in debug mode. When I deploy my app to web I am unable to get the length of an audio file.
That's what I see in the web console:

main.dart.js:3437 Uncaught Error: MissingPluginException(No implementation found for method openPlayer on channel xyz.canardoux.flutter_sound_player)
    at Object.d (main.dart.js:3437:19)
    at main.dart.js:67180:15
    at aEz.a (main.dart.js:4820:63)
    at aEz.$2 (main.dart.js:37513:14)
    at aDA.$1 (main.dart.js:37507:21)

    at aa.q3 (main.dart.js:37827:3)
    at axK.$0 (main.dart.js:37863:13)

To Reproduce
Steps to reproduce the behavior:
try to run this piece of code on a web-hosted app:

await _audioPlayer.openPlayer();
    final duration = await _audioPlayer.startPlayer(
      fromURI: url,
    );
