Flutter - Get geocode address from coordinates

问题

I've implemented a reliable way of getting user lat,long coordinates in an app I'm creating, but can't seem to turn these coordinates into a placemark.

I'd also like to figure out what I need to use to print this data.

This is what I'm trying to get this data with:

List<Placemark> place = [];

void _getPlace() async {
  List<Placemark> newPlace = await _geolocator.placemarkFromCoordinates(_position.latitude, _position.longitude);
  print(newPlace);
  setState(() {
    place = newPlace;
  });
}

Thanks

Edit:

After CopsOnRoad's response, I'm getting this error:

You are already there, extra stuff that you need is:

String _address = ""; // create this variable

void _getPlace() async {
  List<Placemark> newPlace = await _geolocator.placemarkFromCoordinates(_position.latitude, _position.longitude);

  // this is all you need
  Placemark placeMark  = newPlace[0]; 
  String name = placeMark.name;
  String subLocality = placeMark.subLocality;
  String locality = placeMark.locality;
  String administrativeArea = placeMark.administrativeArea;
  String postalCode = placeMark.postalCode;
  String country = placeMark.country;
  String address = "${name}, ${subLocality}, ${locality}, ${administrativeArea} ${postalCode}, ${country}";

  print(address);

  setState(() {
    _address = address; // update _address
  });
}
