Navigation (React Navigation)

Setup

• Use @react-navigation/native with @react-navigation/native-stack as default.
• Wrap app root in NavigationContainer.
• Define navigators in dedicated navigation/ folder.
• One file per navigator (RootNavigator.tsx, TabNavigator.tsx, AuthNavigator.tsx).

Typed Routes

• Define RootStackParamList type for every navigator.
• Every route must have explicitly typed params (or undefined if none).
• Use typed useNavigation and useRoute hooks everywhere.
• Never pass untyped route params.
