Add carousel_slider: ^3.0.0
to your pubspec.yaml
dependencies. And import it:
import 'package:carousel_slider/carousel_slider.dart';
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(),
)
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,
onPageChanged: callbackFunction,
scrollDirection: Axis.horizontal,
)
)
Since v2.0.0
, you'll need to pass the options to CarouselOptions
. For each option's usage you can refer to carousel_options.dart.
If you pass the height
parameter, the aspectRatio
parameter will be ignored.
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) =>
Container(
child: Text(itemIndex.toString()),
),
)
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>[
CarouselSlider(
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('โ'),
)
]
);
}
