获取地图上的特定点以获取地点选择器中的位置

Question

如何获取地点选择器插件上特定点的位置？除了在上面的文本框中搜索之外，我还需要获取特定点的纬度和经度。有没有办法触摸一个区域并获取位置？这是我当前的代码。谢谢。

PlacePicker(
            apiKey: "000000000000000000000000000000000",
            initialPosition: HomeScreen.kInitialPosition,
            useCurrentLocation: true,
            selectInitialPosition: true,

            //usePlaceDetailSearch: true,
            onPlacePicked: (result) async {
              selectedPlace = result;
              SharedPreferences prefs =
                  await SharedPreferences.getInstance();
              prefs.setString(
                  "Long", selectedPlace.geometry.location.lng.toString());
              prefs.setString(
                  "Lat", selectedPlace.geometry.location.lat.toString());
              // prefs.setString(
              //     "currentLoc", selectedPlace.formattedAddress.toString());
              Navigator.of(context).pop();
              Navigator.pushReplacement(
                  context,
                  MaterialPageRoute(
                      builder: (BuildContext context) =>
                          BottomNavBarWidget()));

              // setState(() {});
            },
            forceSearchOnZoomChanged: true,
            enableMyLocationButton: true,
            enableMapTypeButton: true,
            usePinPointingSearch: true,
            usePlaceDetailSearch: true,
            hintText: "Search here",
            searchingText: "Searching..",
            initialMapType: MapType.hybrid,
            forceAndroidLocationManager: true,
            pinBuilder: (context, state) {
              if (state == PinState.Idle) {
                return Icon(
                  FontAwesomeIcons.mapPin,
                  color: Colors.red,
                  size: 25,
                );
              } else {
                return Icon(
                  FontAwesomeIcons.locationArrow,
                  size: 20,
                );
              }
            },
          );

仅使用google_maps_flutter 包（地点选择器插件依赖它来显示地图），您可以执行以下操作以在您点击某个区域时获取该区域的位置：

 final GoogleMap googleMap = GoogleMap(
     onMapCreated: onMapCreated,
      initialCameraPosition: _kInitialPosition, //and/or any other parameters
      onTap: (LatLng pos) {
        setState(() {
         //assign pos value to your LatLng 
         print('${pos.latitude}, ${pos.longitude}');
        });
      },
