React Native Navigation

Priority: P0 (CRITICAL)

Use React Navigation (official solution).

Implementation Guidelines

• Architecture: Use Native Stack (createNativeStackNavigator) by default for native performance. Only use JS Stack for custom transitions.
• Deep Linking: Use prefix arrays in linking config. Validate Universal Links (iOS) and App Links (Android). Handle unrecognized paths with a 404 screen.
• Typing: Use NativeStackScreenProps for screens. CompositeScreenProps for nested Navigators. useNavigation must be typed with NativeStackNavigationProp.
• Logic: Use Tab Navigators for bottom navigation. Drawer for side menus. Auth/App split with conditional rendering in NavigationContainer.
• Transitions: Native-like feel via presentation: 'modal'. Custom headerLeft/Right in options.
• Redirection: Handle auth state changes in the top-level Navigator (Auth Stack vs App Stack). Clear the navigation state after logout.
• Data Flow: Use route.params for small IDs only. Use global state (Zustand/RTK) for complex data objects.
