## Installation

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

### Full example

```js
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;

## How to animate to region?

Full example of how to use `animateToRegion()`.

```js
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
        mapRef={mapRef}
        initialRegion={INITIAL_REGION}
        style={{ flex: 1 }}
      />
      <Button onPress={animateToRegion} title="Animate" />
    </>
  );
};

export default App;
```
