Example of Bottom Sheet in React Native

React Native Bottom Sheet

This is an Example of Bottom Sheet in React Native. To make a Bottom Sheet we will use BottomSheet component provided by react-native-btr.

The bottom Sheet was first introduced in android material design and became very popular. Different people use the bottom sheet differently but the simple example which can be seen in day-to-day life is when you share something. When you share any data application opens a bottom sheet to ask you “share via”. We will make the same demo with the bottom sheet in this example.

How to use Bottom Sheet Component?

<BottomSheet
  visible={visible}
  //setting the visibility state of the bottom shee
  onBackButtonPress={toggleBottomNavigationView}
  //Toggling the visibility state on the click of the back botton
  onBackdropPress={toggleBottomNavigationView}
  //Toggling the visibility state
>
{/*Bottom Sheet inner View*/}
  <View style={styles.bottomNavigationView}>
    .....
  </View>
</BottomSheet>

In this example, we will make a button to open a bottom sheet that has some social icons. We will use react-native-elements to make social icons.

Social Icons to show on Bottom Sheet

<SocialIcon
  //Social Icon using react-native-elements
  type="twitter"
  //Type of Social Icon
  onPress={() => {
    //Action to perform on press of Social Icon
    toggleBottomNavigationView();
    alert('twitter');
  }}
/>

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 command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependencies

For installation of the dependencies, open the terminal and jump into your project using.

cd ProjectName

Run the following commands

1. For BottomSheet component you need to install react-native-btr package.
Run the following command for the installation

npm install react-native-btr --save

2. We are going to use SocialIcon component to show the Social icons so for that you have to install react-native-elements and react-native-vector-icons dependencies.
Run the following commands for the installation

npm install @rneui/themed --save

npm install react-native-vector-icons --save

Please visit Example to Use React Native Vector Icons for further instructions to complete the installation of Vector Icons.

npm install @react-native-community/toolbar-android --save

This command will copy all the dependencies into your node_module directory, You can find the directories in node_module. –save is optional, it is just to update the dependencies in your package.json file.

CocoaPods Installation

Now we need to install pods

npx pod-install

Code for the Bottom Sheet

Now Open App.js in any code editor and replace the code with the following code.

App.js

// Example of Bottom Sheet in React Native
// https://aboutreact.com/react-native-bottom-sheet/

// import React in our code
import React, {useState} from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  StyleSheet,
  View,
  Text,
  Button
} from 'react-native';

//import basic react native components
import { BottomSheet } from 'react-native-btr';

//import to show social icons
import { SocialIcon } from '@rneui/themed';

const App = () => {
  const [visible, setVisible] = useState(false);

  const toggleBottomNavigationView = () => {
    //Toggling the visibility state of the bottom sheet
    setVisible(!visible);
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text
          style={{
            fontSize: 20,
            marginBottom: 20,
            textAlign: 'center'
          }}>

        </Text>
        <Button
          onPress={toggleBottomNavigationView}
          //on Press of the button bottom sheet will be visible
          title="Show Bottom Sheet"
        />
        <BottomSheet
          visible={visible}
          //setting the visibility state of the bottom shee
          onBackButtonPress={toggleBottomNavigationView}
          //Toggling the visibility state
          onBackdropPress={toggleBottomNavigationView}
          //Toggling the visibility state
        >
          {/*Bottom Sheet inner View*/}
          <View style={styles.bottomNavigationView}>
            <View
              style={{
                flex: 1,
                flexDirection: 'column',
                justifyContent: 'space-between',

  bottomNavigationView: {
    backgroundColor: '#fff',
    width: '100%',
    height: 250,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device:

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
