There is a package carousel_slider 4.1.1.

Add carousel_slider: ^4.1.1 to your pubspec.yaml dependencies. And import it:

import 'package:carousel_slider/carousel_slider.dart';

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),
