Error: @staticInterop classes should not contain any generative constructors. Use factory constructors instead.

[Leramir1]

When building this app locally on latest flutter version. I ran into an issue with audio

../../../../AppData/Local/Pub/Cache/hosted/pub.dev/audioplayers_web-2.1.0/lib/web_audio_js.dart:8:12: Error: `@staticInterop` classes should
not contain any generative constructors.
Use factory constructors instead.
  external JsAudioContext();

I resolve it by modifying the code it's and implementing factory constructors.

import 'dart:html';
import 'package:js/js.dart';

@JS('AudioContext')
@staticInterop
class JsAudioContext {
  external factory JsAudioContext();
}

extension JsAudioContextExtension on JsAudioContext {
  external MediaElementAudioSourceNode createMediaElementSource(
    AudioElement element,
  );

  external StereoPannerNode createStereoPanner();

  external AudioNode get destination;
}

@JS()
@staticInterop
abstract class AudioNode {
  external factory AudioNode();
}

extension AudioNodeExtension on AudioNode {
  external AudioNode connect(AudioNode audioNode);
}

@JS()
@staticInterop
class AudioParam {
  external factory AudioParam();
}

extension AudioParamExtension on AudioParam {
  external num get value;
  external set value(num value);
}

@JS()
@staticInterop
class StereoPannerNode implements AudioNode {
  external factory StereoPannerNode();
}

extension StereoPannerNodeExtension on StereoPannerNode {
  external AudioParam get pan;
}

@JS()
@staticInterop
class MediaElementAudioSourceNode implements AudioNode {
  external factory MediaElementAudioSourceNode();
}

Although this resolved my issue, and I could hear the audio, I don't believe modifying a file in AppData should be the solution. Any idea on what the actual solution should be? I'm new to using Flutter.
