Hello React Native Friends,
Building a visually appealing and responsive mobile app is crucial in today’s world. React Native, a popular framework for building cross-platform apps, offers powerful tools to achieve this. Flexbox layout is one such essential tool that simplifies the process of structuring your app’s UI components.
Flexbox, short for Flexible Box Layout, is a CSS layout model designed for building user interfaces. Flexbox layout has revolutionized the way developers design user interfaces, providing a powerful and intuitive way to create responsive layouts in web and mobile applications. In React Native, leveraging Flexbox is crucial for crafting beautiful and flexible UIs that adapt to various screen sizes and orientations.

Let’s implement Flexbox in our React Native application.
Our demo application will have a parent container with three boxes:
The parent and child container is a View Component.
import React from 'react'; import { View, StyleSheet } from 'react-native'; const FlexboxExample = () => { return ( <View style={styles.container}> <View style={styles.redBox} /> <View style={styles.whiteBox} /> <View style={styles.blueBox} /> </View> ) } export default FlexboxExample const styles = StyleSheet.create({ container: { backgroundColor: '#454545', }, redBox: { width: 80, height: 80, backgroundColor: 'red', }, whiteBox: { width: 80, height: 80, backgroundColor: 'white', }, blueBox: { width: 80, height: 80, backgroundColor: 'blue', }, });
Output:
After adding the property is flex: 1, the space is split into a single group; thus, our parent container will display on the entire screen.
container: { backgroundColor: '#454545', flex: 1 },
Output:
The flexDirection property in React Native’s Flexbox layout system determines the primary axis along which flex items are laid out within a flex container.
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row' },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row-reverse' },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'column' },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'column-reverse' },
Output:
Justify Content is used to align the child elements within the main axis of the parent container. You can set the elements horizontally and vertically by setting flexDirection as row and column.
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'flex-start', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'flex-end', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'center', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'space-between', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'space-around', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'space-evenly', },
Output:
AlignItems is used to align the child with the cross axis of its parent container. Similar to justifyContent that aligns with the main axis, this property will align the children with the cross axis.
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'flex-start', alignItems: 'flex-start', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'flex-start', alignItems: 'flex-end', },
Output:
container: { backgroundColor: '#454545', flex: 1, flexDirection: 'row', justifyContent: 'flex-start'', alignItems: 'center', },
Output:
By mastering Flexbox, you’ll gain the ability to create user-friendly and adaptable layouts for your React Native apps. With its intuitive approach and powerful features, Flexbox empowers you to build beautiful and responsive mobile experiences!
