Type-Safe Navigation in React Native with TypeScript
React Navigation uses TypeScript to type-check screens and params, giving you better autocompletion. You define types for route params and augment a global navigator type so hooks like `useNavigation` understand your app's structure.
React Navigation leverages TypeScript for strong type safety across screens, params, and actions, preventing runtime errors and boosting IntelliSense. This involves defining param types with `StaticScreenProps` and augmenting `@react-navigation/core` to declare a global `RootNavigator` type, making `useNavigation` fully type-aware. The footgun is using a generic `useNavigation` hook for navigator-specific methods like `push` or `openDrawer`; you must annotate it with the specific navigator's prop type to access them safely.
