import 'package:flutter_carousel_widget/flutter_carousel_widget.dart';

Usage

Simply create a FlutterCarousel widget, and pass the required params:

FlutterCarousel(
  options: CarouselOptions(
    height: 400.0, 
    showIndicator: true,
    slideIndicator: CircularSlideIndicator(),
  ),
  items: [1,2,3,4,5].map((i) {
    return Builder(
      builder: (BuildContext context) {
        return Container(
          width: MediaQuery.of(context).size.width,
          margin: EdgeInsets.symmetric(horizontal: 5.0),
          decoration: BoxDecoration(
            color: Colors.amber
          ),
          child: Text('text $i', style: TextStyle(fontSize: 16.0),)
        );
      },
    );
  }).toList(),
)

Option Customization

FlutterCarousel(
   items: items,
   options: CarouselOptions(
    height: 400.0,
    aspectRatio: 16 / 9,
    viewportFraction: 1.0,
    initialPage: 0,
    enableInfiniteScroll: true,
    reverse: false,
    autoPlay: false,
    autoPlayInterval: const Duration(seconds: 2),
    autoPlayAnimationDuration: const Duration(milliseconds: 800),
    autoPlayCurve: Curves.fastOutSlowIn,
    enlargeCenterPage: false,
    onPageChanged: callbackFunction,
    pageSnapping: true,
    scrollDirection: Axis.horizontal,
    pauseAutoPlayOnTouch: true,
    pauseAutoPlayOnManualNavigate: true,
    pauseAutoPlayInFiniteScroll: false,
    enlargeStrategy: CenterPageEnlargeStrategy.scale,
    disableCenter: false,
    showIndicator: true,
    floatingIndicator = true,
    slideIndicator: CircularSlideIndicator(),
   )
 )

Build item widgets on demand

This method will save memory by building items once it becomes necessary. This way they won't be built if they're not currently meant to be visible on screen. It can be used to build different child item widgets related to content or by item index.

FlutterCarousel.builder(
  itemCount: 15,
  itemBuilder: (BuildContext context, int itemIndex, int pageViewIndex) =>
    Container(
      child: Text(itemIndex.toString()),
    ),
)

Carousel controller

In order to manually control the pageview's position, you can create your own CarouselController, and pass it to CarouselSlider. Then you can use the CarouselController instance to manipulate the position.

class CarouselDemo extends StatelessWidget {
  CarouselController buttonCarouselController = CarouselController();

 @override
  Widget build(BuildContext context) => Column(
    children: <Widget>[
      FlutterCarousel(
        items: child,
        carouselController: buttonCarouselController,
        options: CarouselOptions(
          autoPlay: false,
          enlargeCenterPage: true,
          viewportFraction: 0.9,
          aspectRatio: 2.0,
          initialPage: 2,
        ),
      ),
      RaisedButton(
        onPressed: () => buttonCarouselController.nextPage(
            duration: Duration(milliseconds: 300), curve: Curves.linear),
        child: Text('→'),
      )
    ]
  );
}
