Rendering Widgets on annotation click repeats on ios

When I tap an annotation, I expect a bottomsheet to show some details about the annotation clicked.
It works fine on android but triggers multiple bottomsheet in ios emulator.

See my code:

class AnnotationClickListener extends OnPointAnnotationClickListener {
  final BuildContext context;
  final List<AirPorts> places;
  final MapboxMap? mapboxMap;

  AnnotationClickListener(this.context, this.places, this.mapboxMap);

  @override
  void onPointAnnotationClick(PointAnnotation annotation) {
    handleAnnotationClick(annotation);
  }

  void handleAnnotationClick(PointAnnotation annotation) {
    String? src;
    String? state;
    Country? country;
    if (annotation.id.isNotEmpty && annotation.geometry != null) {
      final coordinates = annotation.geometry!['coordinates'] as List<dynamic>?;
      if (coordinates != null && coordinates.length >= 2) {
        final double latitude = (coordinates.elementAt(1) as double?) ?? 0.0;
        final double longitude = (coordinates.elementAt(0) as double?) ?? 0.0;

        // Fly to the clicked annotation's coordinates
        mapboxMap?.flyTo(
          CameraOptions(
            zoom: 12.0,
            center: Point(
              coordinates: Position(longitude, latitude),
            ).toJson(),
          ),
          MapAnimationOptions(),
        );

        for (var place in places) {
          if (place.lon == longitude.toString() &&
              place.lat == latitude.toString()) {
            src = place.thumbImage!;
            state = place.state!;
            country = place.country!;
          }
        }

        print('this');

        showModalBottomSheet(
            context: context,
            builder: (BuildContext context) {
              return DiscoverMarkerPopup(
                country: country!,
                src: src!,
                state: state!,
              );
            });
      }
    } else {
      debugPrint('Annotation is null or represents URL images.');
    }
  }
}

Start by reproducing the provided AnnotationClickListener on the iOS emulator and compare its callback behavior with Android. Verify whether one annotation tap invokes the listener more than once, and consider the issue done when each tap produces exactly one bottom sheet without changing the Android behavior.
