Possible to implement drop pin feature ?

[jesussmile]

Currently, to pick a location I am using your showSimplePickerLocation widget, However, is it possible to use it from the OSMflutter widget itself as I have to open two different screens? sth like this? https://pub.dev/packages/map_pin_picker

[liodali]

yeah you can open two different screen and each screen contain its own OSMFlutter

[jesussmile]

I meant in one screen. In osmflutter only. I dont want to open two screen. I want to use the picker in osmflutter widget as it takes time to load the map everytime I use mappicker.. Is that possible or if u could tell how I could do it. I will try it out.

[liodali]

i think to implemented you need some other feature should be add it to plugin like getGeoPointCenter() direclty

[liodali]

i will make more reseach about what mappicker propose to see how i can help you to acheive that

[liodali]

i think you can use pickerMapController and change isPicker OSMFlutter to true and the icon make it invisible or empty widget like SizedBox.shrink() and use method of pickerMapController to getCenterPosition

[jesussmile]

This, is what I want to achieve , Now in my OSMFlutter widget, I can get the MapPicker,

 child: MapPicker(
                    iconWidget: Icon(
                      Icons.location_pin,
                      size: 30,
                      color: Colors.red,
                    ),
                    //add map picker controller
                    mapPickerController: mapPickerController,
                    child: (OSMFlutter(
                      key: _mapKey,
                      controller: osmController,

                      staticPoints: [
                        StaticPositionGeoPoint(
                          driverKey,
                          MarkerIcon(
                            //icon: null,
                            icon: Icon(Icons.star),
                          ),
                          [GeoPoint(latitude: driverLat, longitude: driverLon)],
                        ),
                      ],
                      //currentLocation: false,
                      road: Road(
                        startIcon: MarkerIcon(
                          icon: Icon(
                            Icons.pin_drop,
                            size: 64,
                            color: Colors.green,
                          ),
                        ),
                        roadColor: Colors.yellowAccent,
                      ),
                      markerOption: MarkerOption(
                          defaultMarker: MarkerIcon(
                        icon: Icon(null
                            //Icons.star_half_rounded,
                            //color: Colors.blue,
                            //size: 56,
                            ),
                      )),
                    )),
                  ),

but to get the MapPicker working I need these three functions

onCameraMoveStarted: () {
                  // notify map is moving
                  mapPickerController.mapMoving();
                },
                onCameraMove: (cameraPosition) {
                  this.cameraPosition = cameraPosition;
                },
                onCameraIdle: () async {
                  // notify map stopped moving
                  mapPickerController.mapFinishedMoving();
                  //get address name from camera position
                  List<Address> addresses = await Geocoder.local
                      .findAddressesFromCoordinates(Coordinates(
                      cameraPosition.target.latitude,
                      cameraPosition.target.longitude));
                  // update the ui with the address
                  textController.text='${addresses.first?.addressLine ?? ''}';
                },

I know you are busy, if you can give me few suggestion then I will work on it.

[liodali]

yeah i should add onCameraMoveStarted,onCameraIdle but implementing onCameraIdle will be tricky on the android side

[liodali]

i can add getCenterPosition and you can compare between current value and previous to start or finishMoving

[jesussmile]

Okay! That would be great!

[liodali]

try to put isPicker in OSMFlutter to true and use PickerMapController as Controller and use this method getCurrentPositionAdvancedPositionPicker to get centerGeoPoint for comparaison between previous and current geoPoint and for icon use any icon with transparent color or withOpacity(0) to make it invisible and size equal to 0

[jesussmile]

Oh! That should work I think. I will give it a try. Thank you.
