ShapeSource dynamic clusterRadius

[nickmcblain]

Hey everyone,

I am trying to dynamically change the clusterRadius value on the ShapeSource component but it doesn't seem to account for any change in value. At the moment I have a state variable which maps to the clusterRadius prop and the value is changed upon click of either of 3 filter buttons.

I want the cluster radius to reduce based on the number of symbols I am displaying.

Does anyone know how I could accomplish this?

Hi I thinks it's just not implemented at the moment.

clusterMaxZoom has it but not other props.

Thanks. I'm trying to identify and attempt this change locally, starting with iOS. Trying to just keep it simple and add the same code as clusterMaxZoom within RNMBXShapeSource but I am running into issues where it says it cannot set property for my source.

// @objc public var clusterRadius : NSNumber?
@objc public var clusterRadius : NSNumber? {
  didSet {
    logged("RNMBXShapeSource.clusterRadius") {
      if let number = clusterRadius?.doubleValue {
        doUpdate { (style) in
          logged("RNMBXShapeSource.doUpdate") {
            try style.setSourceProperty(for: id, property: "clusterRadius", value: number)
          }
        }
      }
    }
  }
}

I can keep digging. But any ideas as to why I may be reaching a hurdle here? I can't see any other differences in how the properties are setup other than within this file.

The code looks ok, actually max zoom doesn't seems to work either - see
