Can not add image to the Snaphotter

This code works with MapBox controller object but when Snapshotter is used, marker is not drawn on the map.

  Future<void> _addMarker() async {
    final bytes = await rootBundle.load(Assets.image.mapPin.keyName);
    final list = bytes.buffer.asUint8List();
    await _snapshotter?.style.addStyleImage(
      'icon',
      1,
      MbxImage(width: 10, height: 10, data: list),
      true,
      [],
      [],
      null,
    );

    final geometry = {
      'type': 'Point',
      'coordinates': [
        widget.coordinates.longitude,
        widget.coordinates.latitude,
      ],
    };
    final data = {'type': 'Feature', 'geometry': geometry};
    final source = {'type': 'geojson', 'data': data};
    await _snapshotter?.style
        .addStyleSource('point_source', json.encode(source));

    final symbolLayer = SymbolLayer(
      id: 'point',
      sourceId: 'point_source',
      symbolPlacement: SymbolPlacement.POINT,
      iconAllowOverlap: true,
      iconAnchor: IconAnchor.BOTTOM_LEFT,
      iconImage: 'icon',
      iconColor: Colors.amber.value,
      iconSize: 1,
    );
    await _snapshotter?.style.addLayer(symbolLayer);
  }

Start at the _addMarker entry point and compare the Snapshotter.style image, source, and layer sequence with the working MapBox controller path described in the issue. Reproduce the supplied example and verify that the marker image is registered and drawn on the snapshot; done means the marker appears when Snapshotter is used.
