dart Flutter geolocator插件Geolocator().placemarkFromAddress()和Geolocator().placemarkFromCoordinates()不起作用

我试图搜索一个地址,然后试图通过地理定位器获得该位置的位置,然后试图将相机位置设置为这个位置,但它不起作用。
我发现Geolocator的两个方法有一些例外。Geolodator的所有其他方法对我来说都很好:

1. Geolocator().placemarkFromAddress()显示:

PlatformException(ERROR_GEOCODING_ADDRESS,服务不可用,null)

2. Geolocator().placemarkFromCoordinates()显示:

PlatformException(ERROR_GEOCODING_COORDINATES,服务不可用,null)

这里我正在尝试的代码:

try {
  List<Placemark> placemark = await Geolocator().placemarkFromAddress(searchAddress);
  Placemark newPlace = placemark[0];
  controller.animateCamera(CameraUpdate.newCameraPosition(CameraPosition(
     target: LatLng(newPlace.position.latitude,newPlace.position.longitude),
     zoom: 15.0,
  )));
}catch(e){
   print(e);
}

placemarkFromCoordinates已从插件geolocator移动到geocoding,只需在pubspec.yaml中添加插件geocoding和用户placemarkFromCoordinates

我从here中找到了这个问题的答案。
我只是重新加载我的手机/设备,它对我来说工作正常。

现在移动到https://pub.dev/packages/geocoding

您必须添加geoCoding插件并使用它如下:

List<Placemark> placemark = await placemarkFromCoordinates(currentLocation.latitude, currentLocation.longitude);
