How to Use navigation in Class Components within React Native

React Native allows us to build beautiful mobile applications, but sometimes you might encounter challenges when dealing with navigation—especially when you mix functional and class components. One common problem is wanting to use navigation in a class component that does not automatically receive it as a prop. In this guide, we’ll explain how to effectively pass the navigation object from a functional component to a class component.

The Problem at Hand

You have a functional component where you have access to the navigation object through React Navigation hooks and want to utilize it in a child class component. Here’s a simple summary of the code structure you’re dealing with:

Parent component: A functional component where navigation can be accessed using hooks.

Child component: A class component that does not automatically receive the navigation prop.

Goal: Pass the navigation object to the child component so it can perform navigation actions (like transitioning to another screen) when triggered.

Example Structure

Let's have a quick look at the existing structure:

The Solution: Passing navigation as Props

If you want to access navigation methods like navigate in your class component, you can easily pass it from the parent functional component as follows:

Step-by-Step Breakdown

Extend the Parent Component: Modify the parent component so that it passes the navigate function to the ChildComponent as a prop.

Update the Child Component: Now you need to utilize that prop in your class component. This is where you’ll directly use this.props.navigate to perform navigation actions.

Conclusion

By passing the navigation prop from a functional component to a class component, you unlock the potential to perform navigation actions seamlessly throughout your application. This approach fosters better integration and functionality within mixed component structures.

Make sure to follow the above steps for successful navigation management in your React Native apps. Happy coding!
