The RN obtains the location function, automatically checks and requests permissions

rn-location.js

export async function getCurrentPosition(onSuccess, onError, error3) {
    if (isAndroid) {
        const granted = await PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION);
        if (!granted) {
            PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION)
                .then((status) => {
                    if (status == PermissionStatus.granted) {
                        //
                        getCurrentPosition(onSuccess, onError, false);
                    }
                    console.log('Location=' + status);
                }).catch((status) => {
                    console.log('Location=' + status);
                });
            return;
        }
    }
    GeoLocation.getCurrentPosition(
        (position) => onSuccess(position),
        (err) => {
            if (err.code === 3 && !error3) {
                getCurrentPosition(onSuccess, onError, true);
            } else {
                onError(err);
            }
        },
        { enableHighAccuracy: !error3, timeout: 1000 },
    )
}

cool, Thanks.
