pixelToLatLng method
Converts pixel point to MapLatLng.
Implementation
MapLatLng pixelToLatLng(Offset position) {
final Offset localPointCenterDiff = Offset(
(_state._size!.width / 2) - position.dx,
(_state._size!.height / 2) - position.dy);
final Offset actualCenterPixelPosition =
_pixelFromLatLng(_state._currentFocalLatLng, _state._currentZoomLevel);
final Offset newCenterPoint =
actualCenterPixelPosition - localPointCenterDiff;
return _pixelToLatLng(newCenterPoint, _state._currentZoomLevel);
}
