Installation #

Add latest version of carousel_slider_plus to your pubspec.yaml dependencies. And import it:

import 'package:carousel_slider_plus/carousel_slider_plus.dart';

How to use #

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

CarouselSlider(
  options: CarouselOptions(height: 400.0),
  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(),
)

Params #

CarouselSlider(
  items: items,
  options: CarouselOptions(
    height: 400,
    aspectRatio: 16/9,
    viewportFraction: 0.8,
    initialPage: 0,
    enableInfiniteScroll: true,
    reverse: false,
    autoPlay: true,
    autoPlayInterval: Duration(seconds: 3),
    autoPlayAnimationDuration: Duration(milliseconds: 800),
    autoPlayCurve: Curves.fastOutSlowIn,
    enlargeCenterPage: true,
    enlargeFactor: 0.3,
    onPageChanged: callbackFunction,
    scrollDirection: Axis.horizontal,
  )
)

If you pass the height parameter, the aspectRatio parameter will be ignored.

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.

CarouselSlider.builder(
  itemCount: 15,
  itemBuilder: (BuildContext context, int itemIndex, int pageViewIndex) {
    return Container(
      child: Text(itemIndex.toString()),
    );
  }
)

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

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

  @override
  Widget build(BuildContext context) => Column(
    children: <Widget>[
      CarouselSlider(
        items: child,
        controller: 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('→'),
      )
    ]
  );
}
