The getter 'rotation' isn't defined for the type 'MapPosition'

The getter 'rotation' isn't defined for the type 'MapPosition'. Try importing the library that defines 'rotation', correcting the name to the name of an existing getter, or defining a getter or field named 'rotation'

code is here below

MapOptions(
              center: _initialcameraposition,
              zoom: 13.0,
              onPositionChanged: (MapPosition position, bool hasGesture) {
                setState(() {
                  _targetcameraposition = position.center!;
                  _rotation = position.rotation;
                });
              },
            )
