renderCustomClusterMarker = (count) => <MyCluster count={count} />

render () {
  const { markers, region } = this.state;
  return (
    <ClusterMap
      renderClusterMarker={this.renderCustomClusterMarker}
      region={region}
    >
      {markers.map((marker) => (
          <Marker {...marker} />
      ))}
    <ClusterMap>
  )
}

MyCluster.jsx

import * as React from 'react';
import { View, Text, StyleSheet } from 'react-native';

export const MyCluster = (props) => {
  const { count } = props;
  return (
    <View style={styles}>
      <Text>{count}</Text>
