Common Problems: RNMapsAirModule Error The error says: TurboModuleRegistry.getEnforcing(...): 'RNMapsAirModule' could not be found. Verify that a module by this name is registered in the native binary.

Fix: This means you are using a library (likely react-native-maps) that requires native code, which is not available in Expo Go. You must use a development build (not Expo Go) to use this module. Run: npx expo run:android or npx expo run:ios to create a development build.

If android doesn't work, you might need to install Android Studio.
