Conclusion

By following the steps outlined above, you should be able to navigate between screens without encountering the frustrating TypeError. Using React Native's useNavigation hook effectively ensures that your components have the navigation functionalities they need.

Don’t let navigation errors deter you from your journey in building amazing applications. Happy coding!
