Swipe back to previous card props

Make sure you set showSecondCard={false} for smoother and proper transitions while going back to previous card.

Methods

To trigger imperative animations, you can use a reference to the Swiper component.

Usage example

render () {
    <View style={styles.container}>
        <Swiper
            cards={['DO', 'MORE', 'OF', 'WHAT', 'MAKES', 'YOU', 'HAPPY']}
            renderCard={(card) => {
                return (
                    <View style={styles.card}>
                        <Text style={styles.text}>{card}</Text>
                    </View>
                )
            }}
            onSwiped={(cardIndex) => {console.log(cardIndex)}}
            onSwipedAll={() => {console.log('onSwipedAll')}}
            cardIndex={0}
            backgroundColor={'#4FD0E9'}
            stackSize= {3}>
            <Button
                onPress={() => {console.log('oulala')}}
                title="Press me">
                You can press me
            </Button>
        </Swiper>
    </View>
}

Stylesheet example

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#F5FCFF"
  },
  card: {
    flex: 1,
    borderRadius: 4,
    borderWidth: 2,
    borderColor: "#E8E8E8",
    justifyContent: "center",
    backgroundColor: "white"
  },
  text: {
    textAlign: "center",
    fontSize: 50,
    backgroundColor: "transparent"
  }
});

Updating props on card content? (dynamic card content)

Card properties may change, including on already swiped cards, which would yield no effects to users as the cards would no longer be displayed [based on initial issue].

A possible fix for the situation is setting the cardIndex on the parent component whenever deck re-renders are needed.

const { cardIndex } = this.props;
return (<Swiper
  ref={swiper => {
    this.swiper = swiper;
  }}
  {...customSwiperProps}
  cardIndex={cardIndex}
/>)

Passing along the cardIndex to the swiper will allow external changes on the property, thus triggering a re-render of the deck of cards. All onSwipe callbacks return the cardIndex that can be used to push the updated cardIndex to app state (redux or something else).

By making sure that external changes on the cardIndex match those the swiper performs (increment on swipes, decrement on swipeBack) one can ensure no re-renders occur when not needed.

Development

If you've encountered issues while running the example app located in the Example folder, try the following steps:

If you're using yarn

rm -rf node_modules && rm yarn.lock
yarn cache clean
yarn
react-native run-ios
react-native run-android

If you're using npm

rm -rf node_modules && rm package-lock.json
npm cache clean --force
npm install
react-native run-ios
react-native run-android

If bundler doesn't automatically start Simply run yarn start or npm start in the Example folder.

Don't forget to bump project and example versions in package.json whenever you submit a PR.
