MyPoint extends Point does not return values

Hi all

As there is no active discussionsomewhere I ask my question here, event it is not the place to do.
I need to Extend Points with a PointID to be able to load data of this point later in the code

This is how I initialise Points

        pointAnnotationManager?.create(PointAnnotationOptions(
          geometry: **MyPoint(
            coordinates: Position(
              double.parse(place.attributes!.longitude.toString()),
              double.parse(place.attributes!.latitude.toString()),
            ),
            pinNumber: place.id,
            trailPinNumber: place.id,
          ).toJson(),**
          textField: "${place.id}",
          ///ToDo Set textOpacity to 0 when no text should be displayed
          textOpacity: 1,
          textOffset: [0.0, -4.0],
          iconOpacity: 0.5,
          iconSize: 0.75,
          iconOffset: [0.0, -30.0],
          symbolSortKey: 10,
          image: selectedImageData,
        ));

The next step is reading a point when Clicked

class AnnotationClickListener extends OnPointAnnotationClickListener {
  _MapBoxMapScreenState mapState;
  Animation<double>? animation;
  AnimationController? controller;
  AnnotationClickListener(this.mapState);

  @override
  void onPointAnnotationClick(PointAnnotation selectedannotation) async {
    if (await mapState.mapboxMap.style.styleSourceExists("source")) {
      await mapState.mapboxMap.style.removeStyleLayer("layer");
      await mapState.mapboxMap.style.removeStyleSource("source");
    }

    // build route from puck position to the clicked annotation
    final start = await mapState.mapboxMap.style.getPuckPosition();
    **final end = MyPoint.fromJson((selectedannotation.geometry)!.cast());**
    final coordinates = await fetchRouteCoordinates(start, end.coordinates, ZadaApp.mapboxAccessToken);
    final selectedpinNumber = end.pointid;
    final selectedtrailPinNumber = end.trailspointid;

    **print('PinInformation: ${end.pointid}');**
    **print('TrailPintInformation: ${end.trailspointid}');**
  }
}

here is the toJson and fromJson Funcion to serialise end deserialise

part 'utils.g.dart';

@JsonSerializable(explicitToJson: true)
class MyPoint extends Point {
  int? pointid;
  int? trailspointid;
  MyPoint({
    super.bbox,
    required super.coordinates,
    this.pointid,
    this.trailspointid
  });

  @override
  factory MyPoint.fromJson(Map<String, dynamic> json) => _$MyPointFromJson(json);

  @override
  Map<String, dynamic> toJson() => super.serialize(_$MyPointToJson(this));

  @override
  MyPoint clone() => MyPoint(coordinates: coordinates.clone(), bbox: bbox?.clone(), pointid: pointid, trailspointid: trailspointid);

  @override
  int get hashCode => Object.hashAll([
    type,
    ...coordinates,
    if (bbox != null) ...bbox!,
    if (pointid != null) pointid!,
    if (trailspointid != null) trailspointid!,
  ]);

  @override
  bool operator == (Object other) => other is MyPoint
      ? coordinates == other.coordinates
      : false;
}

The output of end.pointid is always empty in the code

print('PinInformation: ${end.pointid}');
print('TrailPintInformation: ${end.trailspointid}');

Any hit are welcome many thanks for your help

Commencez par examiner MyPoint.toJson et MyPoint.fromJson dans la classe présentée, puis comparez-les avec la sérialisation générée par utils.g.dart. Suivez les points d’entrée de la création de PointAnnotation et de AnnotationClickListener.onPointAnnotationClick, et vérifiez que pointid et trailspointid survivent à la sérialisation et sont disponibles après le clic.
