LatLngBounds visibleRegion =
  await gmController.getVisibleRegion();
LatLng centerLatLng = LatLng(
(visibleRegion.northeast.latitude +
        visibleRegion.southwest.latitude) /
    2,
(visibleRegion.northeast.longitude +
        visibleRegion.southwest.longitude) /

          onMapCreated: (GoogleMapController _cntlr) {
            _onMapCreated(_cntlr);
          },
          myLocationEnabled: true,
          onTap: (LatLng latLng) {
            if (_controller != null) {
              _controller!.animateCamera(
                CameraUpdate.newCameraPosition(CameraPosition(target: LatLng(latLng.latitude, latLng.longitude), zoom: 15)),
              );
            }
            _handleTap(latLng);
          },
          markers: _markers,
          gestureRecognizers: Set()
            ..add(

            ),
        ),


   HandleTap method will give you lat long.

_handleTap(LatLng point) {
   latLng = "${num.parse(point.latitude.toStringAsFixed(6))},${num.parse(point.longitude.toStringAsFixed(6))}";
   print("LAT ::: LNG ${latLng}");
 }

    To get the latitude and longitude (LatLng) of a specific position on the screen, you can use the GoogleMapController.getLatLng method.

     LatLng _getLatLng(Offset offset) async {
    return await _mapController.getLatLng(offset);
 }
