How do I choose the location on a map like a Snapp App Map? When the marker moves on the map, the marker stays constant and the location choices will occur with our stoppage

You should add marker in center of map using onRegionIsChanging in <Mapir/> component. See https://github.com/map-ir/mapir-mapbox/blob/ver2.0.0/docs/MapView.md
