BookNest's checkout offers "Pick up in store", so readers need to know where the shops are and which is nearest. This section reads the phone's position with expo-location (57.0.20) and draws the shops with react-native-maps 15,999 , installed with npx expo install expo-location react-native-maps. That command chose react-native-maps 1.27.2, the version Expo SDK 57 6,418 is tested with, although npm 2,036 's latest is 1.29.8; keep the SDK's choice unless a fix you need is newer. Both are native modules, so they need a new development build.
