`dispose()` does not clear `_anyListeners`

[Lo4D]

There is an onAny() function which adds listener to final List _anyListeners = []; in socket.dart.

  /// Adds a listener that will be fired when any event is emitted. The event name is passed as the first argument to the
  /// callback.
  ///
  /// @example
  /// socket.onAny((event, ...args) => {
  ///   console.log(`got ${event}`);
  /// });
  ///
  /// @param listener
  @override
  Socket onAny(AnyEventHandler handler) {
    _anyListeners.add(handler);
    return this;
  }

But dispose() which claims to clear all event listeners never touches that List _anyListeners .

  /// Disposes the socket manually which will destroy, close, disconnect the socket connection
  /// and clear all the event listeners. Unlike [close] or [disconnect] which won't clear
  /// all the event listeners
  ///
  /// @since 0.9.11
  void dispose() {
    disconnect();
    clearListeners();
  }

It does call clearListeners() which is a method in parent class \ file event_emitter.dart

  /// This function unbinds all the handlers for all the events.
  void clearListeners() {
    this._events = new HashMap<String, List<EventHandler>>();
    this._eventsOnce = new HashMap<String, List<EventHandler>>();
    this._eventsAny.clear();
  }

But it does clear only private fields in that file and doesn't touch List _anyListeners

Currently I use that workaround:

socket.dispose();
socket.offAny();

Because offAny() indeed does clear previously mentioned list:

  /// Removes the listener that will be fired when any event is emitted.
  ///
  /// @example
  /// const catchAllListener = (event, ...args) => {
  ///   console.log(`got event ${event}`);
  /// }
  ///
  /// socket.onAny(catchAllListener);
  ///
  /// // remove a specific listener
  /// socket.offAny(catchAllListener);
  ///
  /// // or remove all listeners
  /// socket.offAny();
  ///
  /// @param listener
  @override
  Socket offAny([AnyEventHandler? handler]) {
    if (handler != null) {
      _anyListeners.remove(handler);
    } else {
      _anyListeners.clear();
    }
    return this;
  }

Is that by design?

it could be a bug.
