@override
void debugFillProperties(DiagnosticPropertiesBuilder description) {
  super.debugFillProperties(description);
  description.add(DiagnosticsProperty<ImageInfo>('current', _currentImage, ifNull: 'unresolved', showName: false));
  description.add(ObjectFlagProperty<List<_ImageListenerPair>>(
    'listeners',
    _listeners,
    ifPresent: '${_listeners?.length} listener${_listeners?.length == 1 ? "" : "s" }',
  ));
}
