How to make smooth location tracking react-native-maps

Hi all,

I build an app were I need a location tracking (for pedestrian). I searching a smooth way to way do this. I use watchPositionAsync, each time the position of user change, a function is called and on this function, I use animateToRegion with the new region in parametre and the time. That work well for the region, the camera track smoothly the user but the map does not load when I arrive in a new area unless I drag the map with finger movement.

there is a better way to do this? Or a method to fix the issue?

    followUser = async () => {
        try {
            await Location.watchPositionAsync(GEOLOCATION_OPTIONS, this.locationChanged);
        }
        catch (error) {
            let status = Location.getProviderStatusAsync();
            if (!status.locationServicesEnabled) {
                alert('Veuillez activer la géolocalisation de votre appareil.');
            }
        }
    };

    locationChanged = (location) => {
        const region = {
            longitude: location.coords.longitude,
            latitude: location.coords.latitude,
            latitudeDelta: BASIC_LATITUDE_DELTA,
            longitudeDelta: BASIC_LONGITUDE_DELTA
        };
        this.goToRegion(region);
        this.setState({ currentRegion: region });
    };

    goToRegion = (region) => {
        this.map.animateToRegion(region,1000*2);
    };


<MapView
                    initialRegion={this.state.currentRegion}
                    ref={ref => { this.map = ref; }}
                    showsUserLocation={true}
                    style={{ flex: 1 }}
                    customMapStyle={MAP_STYLE_SAM}
                    mapType={(this.state.switchValue) ? 'hybrid':'standard'}
                    provider='google'
                    onRegionChangeComplete={this.onMapMove}
                    loadingEnable={true}
                    moveOnMarkerPress={false}
                    onPress={this.pressOnMap}
