Introduction

Have you ever faced issues with scrolling in a FlatList in React Native? If you're working on a horizontal FlatList that displays data in multiple rows but can't achieve the desired horizontal scrolling functionality, you're not alone! Many React Native developers encounter this frustrating scenario.

In this guide, we'll walk through a common problem faced by developers and provide a thorough solution to effectively create a horizontal scrolling FlatList with multiple rows.

The Problem

While trying to implement a FlatList that supports multiple rows and horizontal scrolling, many developers soon realize that the default configurations do not facilitate this smoothly. They may find that the FlatList is rendered, but scrolling is confined to the vertical direction.

As stated in the query, the objective is to create a visually appealing FlatList layout consisting of two rows, where users can scroll horizontally. Below is the original implementation:

The Solution

The solution to enabling horizontal scrolling in your FlatList with multiple rows is simpler than you might think! The key is to wrap your FlatList within a ScrollView. This adjustment allows users to scroll horizontally through the rows of content effortlessly.

Here's How to Implement It

Points to Remember

ScrollView Usage: Only use ScrollView when you need to scroll multiple columns horizontally. Overusing it can lead to performance issues if you have a large dataset.

Performance Consideration: Always be cautious with performance when using ScrollView and FlatList together. For large datasets, consider optimizing your lists with pagination or other techniques.

Conclusion

By simply wrapping your FlatList with a ScrollView, you solve the problem of horizontal scrolling and enhance the user experience in your React Native application. Now your app can display data in a more visually appealing format with smooth scrolling functionality!
