React Native Paper Bottom Navigation New update

React Native Paper is a popular UI library for building React Native applications. It provides a set of reusable components that follow Google’s Material Design guidelines. One of the components it provides is the Bottom Navigation, which is used to navigate between different screens in the application.

To use React Native Paper’s Bottom Navigation component, you will first need to install the library by running the following command:

java
npm install react-native-paper

Once you have installed the library, you can import the BottomNavigation component and use it in your code like this:

javascript
import * as React from 'react';
import { BottomNavigation, Text } from 'react-native-paper';

const HomeScreen = () => <Text>Home</Text>;
const SettingsScreen = () => <Text>Settings</Text>;

const BottomNav = () => {
  const [index, setIndex] = React.useState(0);
  const [routes] = React.useState([
    { key: 'home', title: 'Home', icon: 'home' },
    { key: 'settings', title: 'Settings', icon: 'settings' },
  ]);

  const renderScene = BottomNavigation.SceneMap({
    home: HomeScreen,
    settings: SettingsScreen,
  });

  return (
    <BottomNavigation
      navigationState={{ index, routes }}
      onIndexChange={setIndex}
      renderScene={renderScene}
    />
  );
};

export default BottomNav;

In this example, we have defined two screens, HomeScreen and SettingsScreen, and added them to the routes array along with their respective icons. We then use the BottomNavigation.SceneMap method to create a mapping between the screens and their respective components. Finally, we render the BottomNavigation component and pass in the navigationState, onIndexChange, and renderScene props.

The navigationState prop is an object that contains the current index and the list of routes. The onIndexChange prop is a function that is called when the user taps on a different screen. The renderScene prop is a function that maps each route to its respective component.

You can customize the appearance of the Bottom Navigation component by passing in additional props such as color, shifting, labeled, and barStyle. For more information, you can refer to the React Native Paper documentation.

Sure! Here’s an example of how to implement a bottom navigation using React Native Paper:

First, install the necessary dependencies:

java
npm install react-native-paper @react-navigation/native @react-navigation/bottom-tabs

Then, create a new component for your bottom navigation:

javascript
import * as React from 'react';
import { BottomNavigation, Text } from 'react-native-paper';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';

const MusicRoute = () => <Text>Music</Text>;

const AlbumsRoute = () => <Text>Albums</Text>;

const RecentsRoute = () => <Text>Recents</Text>;

const Tab = createBottomTabNavigator();

const MyTabs = () => {
  const [index, setIndex] = React.useState(0);
  const [routes] = React.useState([
    { key: 'music', title: 'Music', icon: 'queue-music' },
    { key: 'albums', title: 'Albums', icon: 'album' },
    { key: 'recents', title: 'Recents', icon: 'history' },
  ]);

  const renderScene = BottomNavigation.SceneMap({
    music: MusicRoute,
    albums: AlbumsRoute,
    recents: RecentsRoute,
  });

  const renderTabBar = props => (
    <BottomNavigation {...props} />
  );

  return (
    <Tab.Navigator
      initialRouteName="music"
      tabBar={renderTabBar}
    >
      <Tab.Screen
        name="music"
        component={MusicRoute}
        options={{
          tabBarLabel: 'Music',
          tabBarIcon: 'queue-music',
        }}
      />
      <Tab.Screen
        name="albums"
        component={AlbumsRoute}
        options={{
          tabBarLabel: 'Albums',
          tabBarIcon: 'album',
        }}
      />
      <Tab.Screen
        name="recents"
        component={RecentsRoute}
        options={{
          tabBarLabel: 'Recents',
          tabBarIcon: 'history',
        }}
      />
    </Tab.Navigator>
  );
};

export default MyTabs;

In this example, we’re using the BottomNavigation and Text components from react-native-paper, as well as the createBottomTabNavigator function from @react-navigation/bottom-tabs.

We’re creating three different routes for our bottom navigation, each with their own component: MusicRoute, AlbumsRoute, and RecentsRoute.

We’re then using the createBottomTabNavigator function to create a new tab navigator, with three different screens: MusicRoute, AlbumsRoute, and RecentsRoute. We’re also using the BottomNavigation component to render the bottom navigation itself.

Finally, we’re using the options prop for each screen to define the title and icon for each tab in the bottom navigation.

That’s it! You should now have a working bottom navigation using React Native Paper.

React Native Paper is a UI library for React Native that provides customizable components for building mobile applications. It is available as an npm package and can be installed using the following command:

java
npm install react-native-paper

Once installed, you can import the components you need from the package and use them in your React Native application. For example, to use the Button component, you would import it like this:

python
import { Button } from 'react-native-paper';

Then, you can use the Button component in your JSX code like this:

javascript
<Button mode="contained" onPress={() => console.log('Pressed')}>
  Press me
</Button>

React Native Paper provides a wide range of customizable components, such as buttons, text inputs, navigation bars, and more. You can learn more about the available components and how to use them by checking out the React Native Paper documentation.
