Hi Guys,

This article is focused on bottom tab navigation example in react native. This post will give you simple example of how to use bottom tab navigation in react native. This tutorial will give you simple example of how to implement bottom tab navigation in react native. In this article, we will implement a react native bottom tab navigation example.

A simple tab bar on the bottom of the screen that lets you switch between different routes. Routes are lazily initialized -- their screen components are not mounted until they are first focused.

In this example, there are 4 screens (Home, Cart, Images, and Profile) defined using the Tab.Screen component. Similarly, you can define as many screens as you like.

In the first step run the following command to create a project.

expo init BottomTabNavigation

First, you need to install them in your project:

npm install @react-navigation/native     

after all you need to install bottom tab navigation:

npm install @react-navigation/bottom-tabs

you can set bottom tab icon to install vector icons:

npm i react-native-vector-icons

you have use any bundled Icon

import Icon from 'react-native-vector-icons/FontAwesome5';

Now, you need to wrap the whole app in NavigationContainer. Usually you'd do this in your entry file, such as App.js:

In this step, You will open the App.js file and put the code.

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import Icon from 'react-native-vector-icons/FontAwesome5';

const HomeScreen = () => {
    return(
        <View style={styles.container}>
            <Text style={styles.text}>HomeScreen</Text>
        </View>
    );
}

const CartScreen  = () => {
    return(
        <View style={styles.container}>
            <Text style={styles.text}>CartScreen</Text>
        </View>
    );
}

const ImageScreen = () => {
    return(
        <View style={styles.container}>
            <Text style={styles.text}>ImageScreen</Text>
        </View>
    );
}

const ProfileScreen = () => {
    return(
        <View style={styles.container}>
            <Text style={styles.text}>ProfileScreen</Text>
        </View>
    );
}

const Tab = createBottomTabNavigator();

const App = () => {
    return (
        <NavigationContainer>
            <Tab.Navigator>
                <Tab.Screen 
                    name='Home' 
                    component={HomeScreen}
                    options={{ 
                        tabBarIcon: ({ color, size }) => (
                            <Icon name="home" color={color} size={size} />
                        ),
                    }}
                />
                <Tab.Screen 
                    name='Cart'
                    component={CartScreen} 
                    options={{ 
                        tabBarIcon: ({ color, size }) => (
                            <Icon name="shopping-cart" color={color} size={size} />
                        ),
                    }}
                />
                <Tab.Screen 
                    name='Images'
                    component={ImageScreen} 
                    options={{ 
                        tabBarIcon: ({ color, size }) => (
                            <Icon name="images" color={color} size={size} />
                        ),
                    }}
                />
                <Tab.Screen 
                    name='Profile'
                    component={ProfileScreen} 
                    options={{ 
                        tabBarIcon: ({ color, size }) => (
                            <Icon name="user" color={color} size={size} />
                        ),
                    }}
                />
            </Tab.Navigator>
        </NavigationContainer>
    );
}

const styles = StyleSheet.create({
    container: {
        flex:1,
        justifyContent:'center',
        alignItems:'center',
    },
    text: {
        fontSize:20,
    },
});

export default App;

In the last step run your project using the below command.

expo start
