Are clusterProperties not implemented for iOS?

Hi there,

Referencing this comment:

https://github.com/m0nac0/flutter-maplibre-gl/blob/d2463047306140b747c5f9f692d32d80078fe63e/ios/Classes/SourcePropertyConverter.swift#L102

I've been trying to implement cluster coloring via clusterProperties to use to count the number of like properties and color the cluster accordingly. I'm testing on iOS.

I'm using the following expression for clusterProperties:

var source = GeojsonSourceProperties(
        data: observationLayer,
        cluster: true,
        clusterMaxZoom: 17,
        clusterRadius: 20,
        clusterProperties: {
          "nonCompliantCount": [
            '+',
            ['get', 'nonCompliant']
          ],
          "nullCompliantCount": [
            '+',
            ['get', 'nullCompliant']
          ],
        },
      );

Then I try to access the nonCompliantCount and nullCompliantCount aggregators in the cluster layer, and it is null, as in:

      var clusterProperties = CircleLayerProperties(
        // circleColor: '#34C759',
        circleColor: [
          'case',
          [
            '>',
            ['get', 'nonCompliantCount'],
            0
          ],
          '#D10505',
          [
            '>',
            ['get', 'nullCompliantCount'],
            0
          ],
          '#5C7070',
          '#34C759',
        ],
        circleStrokeWidth: 2,
        circleStrokeColor: '#FFF',
        circleRadius: [
          "step",
          ["get", "point_count"],
          20,
          100,
          30,
          750,
          40
        ],
      );

      addLayerOps.add(mapController.addLayer(
        'observations',
        'observation-clusters',
        clusterProperties,
        filter: [
          "has",
          "point_count",
        ],
      ));

Please let me know if this is not supported at the moment, thank you!

I also tested android, and cluster properties are not working there either. clusterProperties are working good in our node/.vue backend however.

Same here. Also missing getClusterExpansionZoom method to handle cluster zoom.

I just stumbled across the same issue, trying to color clusters based on the most common properties within the cluster.

Is there any workaround?
