Installation

npm install react-native-map-clustering react-native-maps --save
// yarn add react-native-map-clustering react-native-maps

Full example

import React from "react";
import MapView from "react-native-map-clustering";
import { Marker } from "react-native-maps";

const INITIAL_REGION = {
  latitude: 52.5,
  longitude: 19.2,
  latitudeDelta: 8.5,
  longitudeDelta: 8.5,
};

const App = () => (
  <MapView initialRegion={INITIAL_REGION} style={{ flex: 1 }}>
    <Marker coordinate={{ latitude: 52.4, longitude: 18.7 }} />
    <Marker coordinate={{ latitude: 52.1, longitude: 18.4 }} />
    <Marker coordinate={{ latitude: 52.6, longitude: 18.3 }} />
    <Marker coordinate={{ latitude: 51.6, longitude: 18.0 }} />
    <Marker coordinate={{ latitude: 53.1, longitude: 18.8 }} />
    <Marker coordinate={{ latitude: 52.9, longitude: 19.4 }} />
    <Marker coordinate={{ latitude: 52.2, longitude: 21 }} />
    <Marker coordinate={{ latitude: 52.4, longitude: 21 }} />
    <Marker coordinate={{ latitude: 51.8, longitude: 20 }} />
  </MapView>
);

export default App;

| Name | Type | Default | Note | | ------------------------------------------- | --------------------- | -------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | clusterColor | String | #00B386 | Background color of cluster. | | clusterTextColor | String | #FFFFFF | Color of text in cluster. | | clusterFontFamily | String | undefined | Font family of text in cluster. | | onClusterPress(cluster, markers) | Function | () => {} | Allows you to control cluster on click event. Function returns information about cluster and its markers. | | tracksViewChanges | Bool | false | Sets whether the cluster markers should track view changes. It's turned off by default to improve cluster markers performance. | | width | Number | window width | map's width. | | height | Number | window height | map's height. | | radius | Number | window.width * 6% | SuperCluster radius. | | extent | Number | 512 | SuperCluster extent. | | minZoom | Number | 1 | SuperCluster minZoom. | | maxZoom | Number | 20 | SuperCluster maxZoom. | | minPoints | Number | 2 | SuperCluster minPoints. | | preserveClusterPressBehavior | Bool | false | If set to true, after clicking on cluster it will not be zoomed. | | edgePadding | Object | { top: 50, left: 50, bottom: 50, right: 50 } | Edge padding for react-native-maps's fitToCoordinates method, called in onClusterPress for fitting to pressed cluster children. | | animationEnabled | Bool | true | Animate imploding/exploding of clusters' markers and clusters size change. Works only on iOS. | | layoutAnimationConf | LayoutAnimationConfig | LayoutAnimation.Presets.spring | LayoutAnimation.Presets.spring | Custom Layout animation configuration object for clusters animation during implode / explode Works only on iOS. | | onRegionChangeComplete(region, markers) | Function | () => {} | Called when map's region changes. In return you get current region and markers data. | | onMarkersChange(markers) | Function | () => {} | Called when markers change. In return you get markers data. | | superClusterRef | MutableRefObject | {} | Return reference to supercluster library. You can read more about options it has here. | | clusteringEnabled | Bool | true | Set true to enable and false to disable clustering. | | spiralEnabled | Bool | true | Set true to enable and false to disable spiral view. | | renderCluster | Function | undefined | Enables you to render custom cluster with custom styles and logic. | | spiderLineColor | String | #FF0000 | Enables you to set color of spider line which joins spiral location with center location. |

How to animate to region?

Full example of how to use animateToRegion().

import React, { useRef } from "react";
import { Button } from "react-native";
import MapView from "react-native-map-clustering";
import { Marker } from "react-native-maps";

const INITIAL_REGION = {
  latitude: 52.5,
  longitude: 19.2,
  latitudeDelta: 8.5,
  longitudeDelta: 8.5,
};

const App = () => {
  const mapRef = useRef();

  const animateToRegion = () => {
    let region = {
      latitude: 42.5,
      longitude: 15.2,
      latitudeDelta: 7.5,
      longitudeDelta: 7.5,
    };

    mapRef.current.animateToRegion(region, 2000);
  };

  return (
    <>
      <MapView
        ref={mapRef}
        initialRegion={INITIAL_REGION}
        style={{ flex: 1 }}
      />
      <Button onPress={animateToRegion} title="Animate" />
    </>
  );
};

export default App;
