This definition is incorrect because it fails to properly de-structure the props, leading to confusion in how React handles children.

Key Steps to Successfully Fix the Issue:

Conclusion

By following these steps, you should easily solve the header issue in your React Navigation 6 application. Properly handling props is vital for the smooth operation of your components. Remember to always check how you're passing and de-structuring props in your custom components.

Next time you're creating a header or any component that relies on props, make sure to use de-structuring to keep your components clean and avoid frustrating errors.
