# NavigationBar

A Jetpack Compose NavigationBar component for Material 3 bottom navigation.
Android, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

Expo UI NavigationBar matches the official Jetpack Compose [`NavigationBar`](https://developer.android.com/develop/ui/compose/components/navigation-bar) API. It displays a row of destinations for switching between top-level app sections.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Basic navigation bar

Manage the selected item in React state and pass `selected` to each `NavigationBarItem`.

```tsx
import { useState } from 'react';
import { Host, Icon, NavigationBar, NavigationBarItem, Text } from '@expo/ui/jetpack-compose';

const HOME_ICON = require('./assets/home.xml');
const SEARCH_ICON = require('./assets/search.xml');
const SETTINGS_ICON = require('./assets/settings.xml');

export default function BasicNavigationBar() {
  const [selectedTab, setSelectedTab] = useState('home');

  return (
    <Host matchContents>
      <NavigationBar>
        <NavigationBarItem selected={selectedTab === 'home'} onClick={() => setSelectedTab('home')}>
          <NavigationBarItem.Icon>
            <Icon source={HOME_ICON} />
          </NavigationBarItem.Icon>
          <NavigationBarItem.Label>
            <Text>Home</Text>
          </NavigationBarItem.Label>
        </NavigationBarItem>

        <NavigationBarItem
          selected={selectedTab === 'search'}
          onClick={() => setSelectedTab('search')}>
          <NavigationBarItem.Icon>
            <Icon source={SEARCH_ICON} />
          </NavigationBarItem.Icon>
          <NavigationBarItem.Label>
            <Text>Search</Text>
          </NavigationBarItem.Label>
        </NavigationBarItem>

        <NavigationBarItem
          selected={selectedTab === 'settings'}
          onClick={() => setSelectedTab('settings')}>
          <NavigationBarItem.Icon>
            <Icon source={SETTINGS_ICON} />
          </NavigationBarItem.Icon>
          <NavigationBarItem.Label>
            <Text>Settings</Text>
          </NavigationBarItem.Label>
        </NavigationBarItem>
      </NavigationBar>
    </Host>
  );
