Using renderItems and data

import React from 'react';
import { Text, Dimensions, StyleSheet, View } from 'react-native';
import { SwiperFlatList } from '@hishprorg/vero-molestias';

const colors = ['tomato', 'thistle', 'skyblue', 'teal'];

const App = () => (
  <View style={styles.container}>
    <SwiperFlatList
      autoplay
      autoplayDelay={2}
      autoplayLoop
      index={2}
      showPagination
      data={colors}
      renderItem={({ item }) => (
        <View style={[styles.child, { backgroundColor: item }]}>
          <Text style={styles.text}>{item}</Text>
        </View>
      )}
    />
  </View>
);

const { width } = Dimensions.get('window');
const styles = StyleSheet.create({
  container: { flex: 1, backgroundColor: 'white' },
  child: { width, justifyContent: 'center' },
  text: { fontSize: width * 0.5, textAlign: 'center' },
});

export default App;

Using children

import React from 'react';
import { Text, Dimensions, StyleSheet, View } from 'react-native';
import { SwiperFlatList } from '@hishprorg/vero-molestias';

const App = () => (
  <View style={styles.container}>
    <SwiperFlatList autoplay autoplayDelay={2} autoplayLoop index={2} showPagination>
      <View style={[styles.child, { backgroundColor: 'tomato' }]}>
        <Text style={styles.text}>1</Text>
      </View>
      <View style={[styles.child, { backgroundColor: 'thistle' }]}>
        <Text style={styles.text}>2</Text>
      </View>
      <View style={[styles.child, { backgroundColor: 'skyblue' }]}>
        <Text style={styles.text}>3</Text>
      </View>
      <View style={[styles.child, { backgroundColor: 'teal' }]}>
        <Text style={styles.text}>4</Text>
      </View>
    </SwiperFlatList>
  </View>
);

const { width } = Dimensions.get('window');

const styles = StyleSheet.create({
  container: { flex: 1, backgroundColor: 'white' },
  child: { width, justifyContent: 'center' },
  text: { fontSize: width * 0.5, textAlign: 'center' },
});

export default App;

More props

This is a wrapper around Flatlist, all their props works well and the inherited props too (from ScrollView and VirtualizedList)

Name	Type	Use
scrollToIndex	({ index: number, animated?: boolean}) => void	Scroll to the index
getCurrentIndex	() => number	Returns the current index
getPrevIndex	() => number	Returns the previous index
onChangeIndex	({ index: number, prevIndex: number}) => void	Executed every time the index change, the index change when the user reaches 60% of the next screen

Right To Left

This library support RTL languages, when I18nManager.isRTL is true.

Limitations

• Vertical pagination is not supported on Android. Doc, that is way we have useReactNativeGestureHandler which is a workaround for this issue.
