如何在用flutter构建的世界时间应用程序上同时显示位置和时间

class WorldTimeApp extends StatefulWidget {

  String location = '';
  String time = '';

  @override
  void initState() {
    super.initState();
    getLocation();
  }

  void getLocation() async {
    // 获取设备的位置信息
    Position position = await Geolocator.getCurrentPosition(
        desiredAccuracy: LocationAccuracy.high);

    // 将经纬度转换为地理位置
    List<Placemark> placemarks =
        await placemarkFromCoordinates(position.latitude, position.longitude);
    Placemark placemark = placemarks[0];
    String address =
        '${placemark.locality}, ${placemark.administrativeArea}, ${placemark.country}';
    setState(() {
      location = address;
    });

    // 获取世界各地的时间
    String url = 'http://worldtimeapi.org/api/timezone';
    http.Response response = await http.get(Uri.parse(url));
    List<dynamic> data = jsonDecode(response.body);
    String currentTime = data[0]['datetime'];
    setState(() {

  }

  @override

}
