How to Display Images from Objects in React Native FlatList

When developing applications with React Native, one common challenge developers face is displaying images stored as paths within an object or data structure. This guide will walk you through how to take an image from an object and display it correctly within a FlatList component.

Understanding the Problem

In our use case, we have an array of objects representing dishes, each with properties such as id, name, image, category, label, price, featured, and description. While the textual properties display correctly in a FlatList, the images don't render as expected, leaving an important part of the user experience missing.

Here’s the structure of the DISHES object we’re working with:

The Solution

The issue arises from how React Native handles image assets. When you want to use an image in React Native, it needs to be required statically so that the bundler can find it. Below, we’ll modify the image property in each dish object to require the images correctly.

Step-by-Step Modification

Modify Image Properties: Update the image fields in the DISHES array to use the require function. This informs the React Native bundler that these images should be included in the app’s assets. Here's how it looks after the change:

Ensure File Path is Correct: Confirm that the path inside the require() statement reflects the correct location of your image files relative to the JavaScript file where DISHES is defined.

Using FlatList: Your FlatList setup remains unchanged; it will automatically pick up these updates when rendering each item. Here’s an example of how you integrate it within your FlatList component:

Conclusion

By leveraging the require function to define your image paths, you can ensure that images stored as properties in your objects are properly rendered within your FlatList component in React Native. This not only enhances the visual appeal of your app but also provides a better user experience by showcasing the dish images alongside their descriptions.

So, next time you encounter issues displaying images from objects in React Native, remember to always require your image files directly within the object!
