expo

Expo Router uses file-based routing where every file in the app/ directory becomes a route. Use _layout.tsx files for shared layouts, (group) directories for layout groups, and [param].tsx for dynamic routes with useLocalSearchParams().

Use react-native-keyboard-controller instead of the built-in KeyboardAvoidingView. For forms use KeyboardAwareScrollViewCompat with bottomOffset, and for chat UIs use KeyboardAvoidingView with behavior="padding" plus an inverted FlatList.

Yes, but only version 1.18.0 is compatible with Expo Go—pin it exactly in package.json. Do not add react-native-maps to the plugins array in app.json, as that will crash the app.

The uuid package requires crypto.getRandomValues(), which is unavailable in React Native. Use Date.now() combined with Math.random(), or expo-crypto's Crypto.randomUUID() pinned to version 15.0.x.

No, Android publishing is not currently supported on Replit. Replit's Expo Launch flow handles production builds and App Store submission for iOS only, triggered via the Publish button.

Use permission hooks like Camera.useCameraPermissions() or Location.useForegroundPermissions(). Show a request button when not granted, and if denied with canAskAgain false, show an Open Settings button guarded by a platform check.
