How to Integrate Flutter Google Map in iOS

I, am using google_map_flutter in my app to show google map. It works fine on Android, but in iOS app crashes when I open the page where I integrate the Google Map. The console shows the this error. Thread 1: "-[__NSCFBoolean objectForKey:]: unrecognized selector sent to instance 0x7fff8a4b94f8" terminating with uncaught exception of type NSException

I Also enable Map SDK for Android & Map SDK for iOS and generate the key.

Container(
              width: double.infinity,
              height: double.infinity,
              child: GoogleMap(
                initialCameraPosition: CameraPosition(
                  target: LatLng(10, 10),
                  zoom: 11.0,
                ),
              ),
            )
