How to Display Clicked Images in React Native with Navigation

React Native is a powerful framework for building mobile applications using JavaScript and React. However, when it comes to handling user interactions, such as clicking on images, you might run into a few challenges. One common problem developers face is how to display a clicked image on a different screen based on user navigation.

In this guide, we will guide you through a step-by-step solution to this problem by demonstrating how to navigate between screens and pass the relevant image data.

Understanding the Problem

You have a React Native application where users can tap on images, and you want to show the corresponding image on a new screen. The key elements are:

Each image acts as a button.

Upon clicking an image, the name of the image file should be sent to a new screen for display.

The challenge lies in comparing the received image name and ensuring the corresponding image is displayed correctly.

Solution Overview

To tackle this, we will:

Send the image name and the actual image to the next screen upon clicking.

Use navigation parameters to retrieve and display the image on the new screen.

Step-by-Step Implementation

Step 1: Set Up the Image Buttons

First, let's create the image buttons that users can click. Each button will send the image name and the actual image file when clicked.

TouchableOpacity: This component acts as a button to house your images.

onPress: This triggers the navigation to the next screen while sending the required parameters.

Step 2: Create the Image Display Screen

Now that we have the buttons set up, let's create the new screen that receives the parameters and displays the correct image.

view: This contains the layout for displaying the image and the image name.

navigation.goBack(): This function allows users to return to the previous screen.

Conclusion

By following these steps, you'll be able to create a seamless user experience where clicking an image dynamically displays it on a new screen in your React Native application. This not only enhances the usability of your app but also makes navigation more intuitive for users.

Now you have a solid understanding of how to pass and display image data between screens in React Native. Happy coding!
