callstack/react-native-pager-view: React Native wrapper for the Android ViewPager and iOS UIPageViewController.

This component allows the user to swipe left and right through pages of data. Under the hood it is using the native Android ViewPager and the iOS UIPageViewController implementations. See it in action!

Warning

From version 7.x only new architecture is supported.

In version 6.x support for transitionStyle property has been dropped. More information here.

"@react-native-community/viewpager" library has been changed to react-native-pager-view. Here you can find more information, how to migrate pager view to the latest version

Bun:

bun add react-native-pager-view

Yarn:

yarn add react-native-pager-view

Autolinking will just do the job.

react-native link react-native-pager-view

Follow the instructions in the React Native documentation to manually link the framework or link using Cocoapods by adding this to your Podfile:

pod 'react-native-pager-view', :path => '../node_modules/react-native-pager-view'

include ':react-native-pager-view'
project(':react-native-pager-view').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-pager-view/android')

dependencies {
   ...
   implementation project(':react-native-pager-view')
}

On top, where imports are:

Add import com.reactnativepagerview.PagerViewPackage;

Add the PagerViewPackage class to your list of exported packages.

@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
    new MainReactPackage(),
    new PagerViewPackage()
  );
}

import React from 'react';
import { StyleSheet, View, Text } from 'react-native';
import PagerView from 'react-native-pager-view';

const MyPager = () => {
  return (
    <PagerView style={styles.pagerView} initialPage={0}>
      <View key="1">
        <Text>First page</Text>
      </View>
      <View key="2">
        <Text>Second page</Text>
      </View>
    </PagerView>
  );
};

const styles = StyleSheet.create({
  pagerView: {
    flex: 1,
  },
});

Attention: Note that you can only use View components as children of PagerView (cf. folder /example) . For Android if View has own children, set prop collapsable to false https://reactnative.dev/docs/view#collapsable-android, otherwise react-native might remove those children views and and its children will be rendered as separate pages

For advanced usage please take a look into our example project

See the contributing guide to learn how to contribute to the repository and the development workflow.

• flex:1 does not work for child views, please use width: '100%', height: '100%' instead

• [iOS]: In case of UIViewControllerHierarchyInconsistency error, please use below fix:

requestAnimationFrame(() => refPagerView.current?.setPage(index));

To attach reanimated handler with onPageScroll follow the below steps.

// 1. Define the handler
function usePageScrollHandler(handlers, dependencies) {
  const { context, doDependenciesDiffer } = useHandler(handlers, dependencies);
  const subscribeForEvents = ['onPageScroll'];

  return useEvent(
    (event) => {
      'worklet';
      const { onPageScroll } = handlers;
      if (onPageScroll && event.eventName.endsWith('onPageScroll')) {
        onPageScroll(event, context);
      }
    },
    subscribeForEvents,
    doDependenciesDiffer
  );
}

// 2. Attach the event handler
import PagerView from 'react-native-pager-view';
import Animated from 'react-native-reanimated';
const AnimatedPagerView = Animated.createAnimatedComponent(PagerView);

const pageScrollHandler = usePageScrollHandler({
  onPageScroll: (e) => {
    'worklet';
    offset.value = e.offset;
    console.log(e.offset, e.position);
  },
});

<AnimatedPagerView onPageScroll={pageScrollHandler} />;

The usePagerView hook is a convenient way to manage the state and control the behavior of the <PagerView /> component. It provides functions and variables to interact with the pager, such as navigating between pages and enabling/disabling scrolling.

Below is an example of how to use the usePager hook:

export function PagerHookExample() {
  const { AnimatedPagerView, ref, ...rest } = usePagerView({ pagesAmount: 10 });
  
  return (
    <SafeAreaView style={styles.container}>
      <AnimatedPagerView
        testID="pager-view"
        ref={ref}
        style={styles.PagerView}
        initialPage={0}
        layoutDirection="ltr"
        overdrag={rest.overdragEnabled}
        scrollEnabled={rest.scrollEnabled}
        onPageScroll={rest.onPageScroll}
        onPageSelected={rest.onPageSelected}
        onPageScrollStateChanged={rest.onPageScrollStateChanged}
        pageMargin={10}
        orientation="horizontal"
      >
        {useMemo(
          () =>
            rest.pages.map((_, index) => (
              <View
                testID="pager-view-content"
                key={index}
                style={{
                  flex: 1,
                  backgroundColor: '#fdc08e',
                  alignItems: 'center',
                  padding: 20,
                }}
                collapsable={false}
              >
                <LikeCount />
                <Text testID={`pageNumber${index}`}>
                  {`page number ${index}`}
                </Text>
              </View>
            )),
          [rest.pages]
        )}
      </AnimatedPagerView>
      <NavigationPanel {...rest} />
    </SafeAreaView>
  );
}

• Pager View Setup: The AnimatedPagerView component wraps PagerView in React Native's animation capabilities. It accepts multiple props from the usePager hook, such as overdragEnabled, scrollEnabled, onPageScroll, onPageSelected, and others to manage pager behavior.

• Rendering Pages: The pages are dynamically generated using the rest.pages array (initialized by usePager). The useMemo hook ensures the pages are only recomputed when necessary for performance reasons.

The usePager hook makes it easy to handle pagination with dynamic views. This example demonstrates how to set up a simple paginated interface where users can scroll through pages, interact with page elements, and control the pager with external navigation.
