Here is an example of Bottom Navigation with Navigation Icon from Local Directory. This post is an extension of my previous post on How to Make React Native Bottom Navigation with Latest Navigation V. 3+.
In this example, we are making the same layout and flow as the previous one, Bottom Navigation with navigation options like Home and Setting. Each screen has other navigation options too but this time the navigation tab icon will be from the local directory.
This example is updated for the React Navigation 4.0+. For more about React Navigation 4 please have a look at Using React Navigation 4.0 in React Native apps.
To Make a React Native App
Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run
npm install -g react-native-cliRun the following commands to create a new React Native project
react-native init ProjectNameIf you want to start a new project with a specific React Native version, you can use the --version argument:
react-native init ProjectName --version X.XX.Xreact-native init ProjectName --version react-native@nextThis will make a project structure with an index file named App.js in your project directory.
Installation of Dependencies
To install the dependencies open the terminal and jump into your project
1 | cd ProjectName |
1. Install react-navigation dependency to import createAppContainer
1 | npm install react-navigation --save |
2. Install react-native-gesture-handler dependency to support gesture navigation
1 | npm install react-native-gesture-handler --save |
3. Install react-navigation-tabs to import createBottomTabNavigator
1 | npm install react-navigation-tabs --save |
4. Install react-native-reanimated for the bottom tab animation (Used internally by react-navigation-tabs)
1 | npm install react-native-reanimated --save |
These steps are enough for the bottom tab navigation but in this example we are also using createStackNavigator to switch screeens, so please follow the next step also
5. Install react-navigation-stack to import createStackNavigator
1 | npm install react-navigation-stack --save |
These commands will copy all the dependencies into your node_module directory.
CocoaPods Installation
After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the libraries but need to install pods.
In this example we need to install the pods for react-native-gesture-handler and react-native-reanimated.
Please use the following command to install CocoaPods
1 | cd ios && pod install && cd .. |
Project File Structure
To start with this Example you need to create
- A directory named pages in your project and create four files DetailsScreen.js, HomeScreen.js, ProfileScreen.js and SettingScreen.js in it.
- A directory named asset which will have our icons stored.
Now Open App.js in any code editor and replace the code with the following code.
App.js

Open pages/DetailsScreen.js in any code editor and the Replace the code with the following code.
