PlacePicker Google Location

I am trying to use PlacePicker, so I can use the location from the dropped pin on the map. However, my placepicker does not allows to use the pinned location, but I need to search on search bar. If I zoom or locate the map, searching appears little bit, but mainly it does not allow me to chose the location for the pin. Any help?

PlacePicker(
                            apiKey: "-------------------",
                            initialPosition: LatLng(widget.currentUser.posXuser,
                                widget.currentUser.posYuser),
                            useCurrentLocation: true,
                            selectInitialPosition: true,
                            usePlaceDetailSearch: true,
                            onPlacePicked: (result) {
                              selectedPlace = result;
                              Navigator.of(context).pop();
                              setState(() {
                                eventPlace = selectedPlace.formattedAddress;
                                posX = selectedPlace.geometry.location.lat;
                                posY = selectedPlace.geometry.location.lng;
                              });
                            },
