我想检查地图的边界，以便我可以根据边界应用聚类。
var bounds = map.getBounds();
var ne = bounds.getNorthEast(); // LatLng of the north-east corner
var sw = bounds.getSouthWest(); // LatLng of the south-west corner
我正在使用React-native地图群集的MapView和Marker和react-native-maps的标注。我无法使用animateToRegion。它告诉我this.mapView.animateToRegion is not a function
<MapView
ref={map=>{mapView = map}}
provider='google'
clustering={true}
onClusterPress={this.onPressCluster}
region={this.state.region}
onRegionChange={this.onRegionChange}
onRegionChangeComplete={this.onRegionChangeComplete}
style={styles.map}
showsUserLocation={true}
followUserLocation={true}
zoomEnabled={true}
ScrollEnabled={true}
showsBuildings={true}
showsMyLocationButton={false}/>
