Clusterer: React Native component getLeaves

[BinLei001]

I use Clusterer as React componet. When the point is clicked, if it is a cluster, I need to get all leaves. But Clusterer is a FunctionComponent I tried to use ref, failed. So how do I get superclusterer, and then call its method to getLeaves?

 <Clusterer
      // ref={ref => {this.clusterer = ref}}  can't use ref here
      data={ clusterCollection}
      region={region}
      options={{radius: 18,minZoom:clusterMinZoom}}
      mapDimensions={MAP_DIMENSIONS}
      renderItem={(item) => {
        return (
        <Point
            key={
            item.properties?.cluster_id ?? `point-${item.properties?.id}`
            }
            item={item}
            onPress={(item) => {

            }}
        />
        )
    }}
  />

The Clusterer component is just a simple wrapper and doesn't implement a ref. You can either use the getExpansionRegion() property (before v2.0.0 it was getClusterExpansionRegion()) that is provided for all clusters features in both Clusterer and useClusterer, or implement it yourself with the Supercluster class.
