export const SimpleCarousel = () => {
  return (
    <Carousel
      isInfinity
      isAutoScroll={false}
      fakeImagePerSide={FAKE_PER_SIDE}

Props

Accepts all ScrollView props and these: | name | required | default | types | descriptions | |:----------------------------------|:---------|:---------------------------------- |:-------------------------------------------|:-------------| | images | ✅ | | { id: string; image: ImageSourcePropType } | Images for carousel, you can add local images and form url as well | | fakeImagePerSide | ❌ | 3 | number | Count of fake items per each side | | slideWidth | ❌ | Dimensions.get('window').width | number | Slide width | | isAutoScroll | ❌ | false | boolean | Should images auto scrolling or not | | autoScrollSlideInterval | ❌ | 4000 | number | Time between each autoscroll new slide | | autoScrollSlideInteractionDelay | ❌ | 1000 | number | If you interrupt auto scrolling or just scroll by fingers autoscroll waiting autoScrollSlideInteractionDelay + autoScrollSlideInterval until start next auto scrolling | | slideHorizontalOffset | ❌ | 10 | number | Offset between each slide | | slideAnimationType | ❌ | NEED YO ADD | {MOVE_UP,SCALE,ROLLING,SQUEEZE_ANDROID, SQUEEZE_MOVE_UP_IOS,NO_EFFECTS} | Already implemented animations for slides | | animationDuration | ❌ | 500 | number | Sliding duration during autoscroll or pressing pagination buttons | | slideAlign | ❌ | symmetric | 'symmetric' | 'left' | number | left - all you slides start from left edge (typically for scrollView). symmetric - slides looks symmetric, because adds number depends on device size. number - add any number for specific cases when you need to align your slides (like here). If you use paddingHorizontal inside contentContainerStyle this will override slideAlign because technically slideAlign is paddingHorizontal. | | onSelectSlide | ❌ | undefined | (index: number) => void | Calls on select slide, useful for getting current selected index | | containerWidth | ❌ | | number | This parameter not setting carousel width, it just says parent width. This parameter improves performance. Without one carousel make 1 rerender to defined own width | | dotsAnimationType | ❌ | SCALE_WITH_OPACITY | {SCALE_WITH_OPACITY,SCALE,MOVE_UP} | Already implemented animations for dots | | startFromIndex | ❌ | 0 | number | Sets index of first visible slide | | isInfinity | ❌ | true | boolean | Define should carousel be infinity or not | | dotStyles | ❌ | undefined | ViewStyle | Your custom styles for dots | | dotsContainerStyles | ❌ | undefined | ViewStyle | Your custom styles for dots container | | imageProps | ❌ | {} | Omit<ImageProps, 'source'> | Image props for slide images, like resizeMode, etc... | | imageStyles | ❌ | undefined | ImageStyle | Your custom styles for slide images | | slideStyles | ❌ | undefined | Omit<ViewStyle, 'width'> | Your custom styles for slides | | customSlides | ❌ | undefined | (slideStyles: any[]) => JSX.Element | Replace developed slides by your own implementation | | customSlideAnimation | ❌ | undefined | customSlideAnimation?: (hiddenIndexScrolling: undefined | number,i: number,interpolate: (slideItemIndex: number,minValue: number | string,maxValue: number | string) => any) => any | Custom animations fro slides | | customDots | ❌ | undefined | (dotsStyles: any[]) => JSX.Element | Replace developed dots pagination by your own implementation | | customDotsAnimation | ❌ | undefined | customDotsAnimation?: (i: number,interpolate: (slideItemIndex: number,minValue: number | string,maxValue: number | string) => any) => any | Custom animations fro slides |

Ref

name	required	default	types	descriptions
getCarouselRef	❌	undefined	(ref: {stopAutoPlay: () => void,tryStartAutoPlay: () => void, scrollToIndex: (index: number) => void}) => void	Return CarouselRef for easing handing autoplay and scrolling
getScrollViewRef	❌	undefined	(ref: React.RefObject) => void	Return ScrollView ref

Props

Animations You can use already implemented animations or create own. There are two way to create your custom animations

customDotsAnimation or customSlideAnimation provides you index and interpolate function. You need just add to interpolate index, minValue and maxValue. This useful for common cases, this animation depends on current selected slide

      customDotsAnimation={(index, interpolate) => ({
        transform: [{ translateY: interpolate(index, 0, -20) }],
      })}

Sometimes you may want to add specific animation, for this case nativeEvent for getting current offset and use interpolate on it. For more details see DotsAdvancedAnimation or CustomSlides

import React from 'react'
import { Carousel,  NativeScrollEvent, NativeSyntheticEvent } from 'react-native-carousel-infinity'

const Component = () => {
  const myAnim = useRef(new Animated.Value(0)).current

  const _onScroll = ({ nativeEvent }: NativeSyntheticEvent<NativeScrollEvent>) => {
    const value = nativeEvent.contentOffset.x
    myAnim.setValue(value)
  }

  const renderCustomDots = (dots: any[]) => {
    return (
      <Animated.View
        style={[
          {
            transform: [
              {
                translateX: myAnim.interpolate({
                  inputRange: [900, 960, 1440, 1500],
                  outputRange: [-107.5, 0, 140, 252.5],
                  extrapolate: 'clamp',
                }),
              },
            ],
          },
        ]}
      />
    )
  }

  return <Carousel onScroll={_onScroll} customDots={renderCustomDots} />
}
