With Map view, how to segment stuff inside a region on a map?

my question is how to draw lines on the map view using expo map ?
Any example ?

Hi - Expo uses the Airbnb react native maps. You can find the docs for it in their README on github. Here’s a direct link to the Polyline component which I think might be what you want. react-native-maps/polyline.md at master · react-native-maps/react-native-maps · GitHub
