How to update camera position flutter google map?

Here we will see how to update camera position using flutter google map. First make sure you use GoogleMap() widget and create a google map object in your widget tree.

At the same time make sure that, you have created initial value for Camera Position.

   CameraPosition _cameraPosition=CameraPosition(target:
    LatLng(45.521563, -122.677433),zoom: 17);

If you class is stateful class, make sure that you initialize value before build() method.

Then inside GoogleMap() widget, we need to give value for initialCameraPosition property.

GoogleMap(
                        initialCameraPosition: CameraPosition(target: _initialPosition, zoom: 17),
                        onTap: (latLng) {


                        },
                        zoomControlsEnabled: false,
                        compassEnabled: false,
                        indoorViewEnabled: true,
                        mapToolbarEnabled: false,
                        myLocationEnabled: true,
                        onCameraIdle: () {
                          print("tapping for udpate");
                          //locationController.updatePosition(_cameraPosition, true);
                        },
                        onCameraMove: ((position){
                         
                          _cameraPosition = position;
                        }),
                        onMapCreated: (GoogleMapController controller) {
                          
                          //locationController.setMapController(controller);
                          //locationController.getCurrentLocation(true, mapController: controller);
                        },
                      )

As you can see, get position object for onCameraMove property. Position object is given to _cameraPosition.

But of course, you need to decode the position object using LatLng() class.
