this method change the zoom level of the map by setting direcly the zoomLevel or stepZoom

if stepZoom specified zoomLevel will be ignored if zoomLevel negative,the map will zoomOut

return Future

Will throw exception if zoomLevel > of maxZoomLevel or zoomLevel < minZoomLevel

zoomLevel : (double) should be between minZoomLevel and maxZoomLevel

stepZoom : (double) step zoom that will be added to current zoom

Implementation

Future<void> setZoom({double? zoomLevel, double? stepZoom}) async {
  await osmBaseController.setZoom(zoomLevel: zoomLevel, stepZoom: stepZoom);
}
