this.map.animateCamera is not a function

[tj1122]

Here is my code below

onMapReady = () => { this.map.animateCamera({ pitch: 80, }); };

<ClusterMap ref={r => this.map = r} onRegionChangeComplete={this.onMapReady} style={{flex: 1}} region={this.state.region} customMapStyle={mapStyle} provider={PROVIDER_GOOGLE} showsUserLocation={true} maxZoomLevel={20} renderClusterMarker={this.renderCustomClusterMarker} isClusterExpandClick={true} superClusterOptions={{radius: 20, maxZoom: 15, minZoom: 1, nodeSize: 16}} // annotations={this.state.markers} >
