android-maps-utils 中的 DefaultClusterRenderer 在 v1.2.1 中损坏了吗？

Question

当试图覆盖 DefaultClusterRenderer 中的任何函数时，它不会在 v1.2.1 中编译。在 v1.1.0

中似乎一切正常

在这里我想为集群图标设置颜色，并覆盖 DefaultClusterRenderer onBeforeClusterItemRendered 以根据值设置颜色。

以下代码在 v1.2.1 中失败，在 v1.1.0 中完全正常

package no.rogo.emptyfuel.utilities.cluster

import com.bumptech.glide.load.resource.bitmap.BitmapDrawableEncoder

class CustomClusterRenderer(
    context: Context,
    map: GoogleMap,
    clusterManager: ClusterManager<ClusterStation?>?
) : DefaultClusterRenderer<ClusterStation?>(context,map,clusterManager)
{
    private val TAG by lazy { this::class.java.simpleName }

    private val clusterIconGenerator = IconGenerator(context.applicationContext)

    override fun onBeforeClusterItemRendered(
        item: ClusterStation?,
        markerOptions: MarkerOptions?
    ) {

        var markerHue = when(item?.statusLevel)
        {
            StatusLevel.SINCE_NEW -> BitmapDescriptorFactory.HUE_GREEN
            StatusLevel.SINCE_FAIR -> BitmapDescriptorFactory.HUE_YELLOW
            StatusLevel.SINCE_OLD -> BitmapDescriptorFactory.HUE_RED
            StatusLevel.SINCE_OLDER -> BitmapDescriptorFactory.HUE_BLUE
            StatusLevel.NOT_SET -> BitmapDescriptorFactory.HUE_CYAN
            StatusLevel.NOT_AVAILABLE -> BitmapDescriptorFactory.HUE_AZURE
            StatusLevel.HIDDEN -> BitmapDescriptorFactory.HUE_ROSE
            StatusLevel.UNCERTAIN -> BitmapDescriptorFactory.HUE_ORANGE
            StatusLevel.UNKNOWN -> BitmapDescriptorFactory.HUE_MAGENTA
            else -> BitmapDescriptorFactory.HUE_VIOLET
        }



        //Color.colorToHSV(markerColor,markerHue)

        //Log.i(TAG,"map3: markerHue = ${markerHue[0]}")

        val markerDescriptor = BitmapDescriptorFactory.defaultMarker(markerHue)
        markerOptions?.icon(markerDescriptor)

        super.onBeforeClusterItemRendered(item, markerOptions)
    }

    override fun onClusterItemRendered(clusterItem: ClusterStation?, marker: Marker?) {
        super.onClusterItemRendered(clusterItem, marker)
    }

    override fun onBeforeClusterRendered(
        cluster: Cluster<ClusterStation?>?,
        markerOptions: MarkerOptions?
    ) {
        super.onBeforeClusterRendered(cluster, markerOptions)
    }


}

有谁知道发生了什么变化以及如何解决？

我找到了问题的解决方案，在这个 pull (https://github.com/googlemaps/android-maps-utils/pull/687) 中，他们将参数更改为 nullsafe，因此更改时：

override fun onBeforeClusterItemRendered(
    item: ClusterStation?,
    markerOptions: MarkerOptions?
)

到

override fun onBeforeClusterItemRendered(
    item: ClusterStation, 
    markerOptions: MarkerOptions
)

已修复。这实际上是一个 kotlin 问题...
