颤音地理定位器在某些地区不起作用

Question

我正在我的扑面项目中测试我的地理位置代码。我试图恢复当前位置。当我从法国进行测试时，它可以正常工作。但是在塞内加尔，它行不通。我需要帮助。谢谢。

这是我的代码：

void locationPosistion() async {
    bool serviceEnabled;
    LocationPermission permission;

    // Test if location services are enabled.
    serviceEnabled = await Geolocator.isLocationServiceEnabled();
    if (!serviceEnabled) {
      return Future.error('Location services are disabled.');
    }

    permission = await Geolocator.checkPermission();
    if (permission == LocationPermission.denied) {
      permission = await Geolocator.requestPermission();
      if (permission == LocationPermission.denied) {
        return Future.error('Location permissions are denied');
      }
    }

    if (permission == LocationPermission.deniedForever) {
      // Permissions are denied forever, handle appropriately.
      return Future.error(
          'Location permissions are permanently denied, we cannot request permissions.');
    }

    Position position = await Geolocator.getCurrentPosition(
        desiredAccuracy: LocationAccuracy.high,
        forceAndroidLocationManager: true);

    currentPosition = position;

    LatLng latLngPosition = LatLng(position.latitude, position.longitude);

    CameraPosition cameraPosition =
        CameraPosition(target: latLngPosition, zoom: 14);
    newGoogleMapController
        .animateCamera(CameraUpdate.newCameraPosition(cameraPosition));

 
  }
