Code Examples for Carousel Slider Flutter
Now that we have discussed the features and benefits of Carousel Slider Flutter let's dive into some code examples that demonstrate how to use the package to create beautiful and dynamic carousels in Flutter applications.
Example 1:
To add the Carousel Slider package to your Flutter project, you need to include the following dependencies in your pubspec.yaml file.
dependencies:
carousel_slider: ^2.3.1
In the next step, create a new Flutter project, import the carousel_slider package in your main.dart file, and add the following code snippet.
import 'package:carousel_slider/carousel_slider.dart';
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: CarouselSlider(
options: CarouselOptions(
height: 400.0,
enlargeCenterPage: true,
enableInfiniteScroll: true,
autoPlay: true,
autoPlayInterval: Duration(seconds: 2),
autoPlayAnimationDuration: Duration(milliseconds: 800),
autoPlayCurve: Curves.fastOutSlowIn,
pauseAutoPlayOnTouch: true,
scrollDirection: Axis.horizontal,
),
items: [
Container(
decoration: BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.circular(10),
),
child: Center(
child: Text(
'Slide 1',
style: TextStyle(fontSize: 22, color: Colors.white),
),
),
),
Container(
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(10),
),
child: Center(
child: Text(
'Slide 2',
style: TextStyle(fontSize: 22, color: Colors.white),
),
),
),
Container(
decoration: BoxDecoration(
color: Colors.green,
borderRadius: BorderRadius.circular(10),
),
child: Center(
child: Text(
'Slide 3',
style: TextStyle(fontSize: 22, color: Colors.white),
),
),
),
],
),
),
);
}
}
Explanation:
In the above code snippet, we have created a simple carousel slider with three slides (red, blue, and green). Here, the Center widget is used to position the carousel slider in the center of the screen. The CarouselSlider widget is used to create the carousel itself, and the options parameter is used to customize the carousel's appearance and behavior.
Example 2:
Let's add some more advanced features to the Carousel Slider and see how it affects the carousel. Here's the code snippet for the same:
import 'package:carousel_slider/carousel_slider.dart';
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Carousel Slider Example'),
backgroundColor: Colors.blue,
),
body: Container(
margin: EdgeInsets.all(8),
child: CarouselSlider(
options: CarouselOptions(
height: 350,
enlargeCenterPage: false,
autoPlay: true,
autoPlayInterval: Duration(seconds: 3),
autoPlayAnimationDuration: Duration(milliseconds: 500),
autoPlayCurve: Curves.fastOutSlowIn,
pauseAutoPlayOnTouch: true,
aspectRatio: 1 / 1,
scrollDirection: Axis.horizontal,
onPageChanged: (index, reason) {
//TODO: add your onPageChanged logic here
},
enableInfiniteScroll: true,
viewportFraction: 0.8,
),
items: [
'https://picsum.photos/350/200?image=1',
'https://picsum.photos/350/200?image=2',
'https://picsum.photos/350/200?image=3',
'https://picsum.photos/350/200?image=4',
'https://picsum.photos/350/200?image=5',
'https://picsum.photos/350/200?image=6',
].map((url) {
return Builder(
builder: (BuildContext context) {
return Container(
width: MediaQuery.of(context).size.width,
margin: EdgeInsets.symmetric(horizontal: 5.0),
decoration: BoxDecoration(
color: Colors.grey.withOpacity(0.5),
borderRadius: BorderRadius.circular(10),
image: DecorationImage(
image: NetworkImage(url),
fit: BoxFit.cover,
),
),
child: Column(
mainAxisAlignment: MainAxisAlignment.end,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
margin: EdgeInsets.only(left: 8, bottom: 4),
child: Text(
'Lorem Ipsum is simply dummy text of the printing and typesetting industry.',
style: TextStyle(
fontSize: 14,
color: Colors.white,
),
),
),
Container(
margin: EdgeInsets.only(left: 8, bottom: 8),
child: Text(
"By John Doe",
style: TextStyle(
fontSize: 12,
color: Colors.white,
),
),
),
],
),
);
},
);
}).toList(),
),
),
);
}
}
Explanation:
In the above code snippet, we have created a more advanced carousel slider example that contains some of the most commonly used features. Here, we have created a carousel slider with six slides, which are fetched from the web using the Picsum API. We have also added the CarouselOptions parameter to customize the carousel's appearance and behavior, added an aspect ratio to each slide, and used the Builder-widget to create a container with a background image. The container contains two text containers with white fonts, which are positioned at the bottom of each slide.
