Let’s start the implementation
To Implement the Carousel Slider in Flutter you have to follow the following steps:
1: First add Carousel Slider dependency in your pubspec.yaml file
|
1 2 3 4 |
dependencies: carousel_slider: ^4.0.0 |
2: Let’s move to the next part
Here we will create the class for our demo (In my case “MyHomePage” )
|
1 2 3 4 5 6 7 8 9 10 11 |
class MyHomePage extends StatelessWidget { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('Carousel Demo'), ), body: Center(child: getSlider()), //===Will find the function in next step ); } } |
3: In this step, we will set up our slider according to our needs
In my case, I have used a simple container with a center align text field.
Note:- This is just a demo code you can modify this according to your needs
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
Widget getSlider() { return CarouselSlider( options: getOptions(), //=====Find the options in next step 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: const BoxDecoration(color: Colors.amber), child: Center( child: Text( 'text $i', style: const TextStyle(fontSize: 16.0), ), )); }, ); }).toList(), ); } |
4: In this step, we will set up our slider options
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
CarouselOptions getOptions() { return CarouselOptions( height: 400, aspectRatio: 16 / 9, viewportFraction: 0.8, initialPage: 0, enableInfiniteScroll: true, reverse: false, autoPlay: true, autoPlayInterval: const Duration(seconds: 3), autoPlayAnimationDuration: const Duration(milliseconds: 800), autoPlayCurve: Curves.fastOutSlowIn, enlargeCenterPage: true, onPageChanged: (position, reason){ print("Current Position:- $position"); print("Change Reason:- ${reason.name}"); }, scrollDirection: Axis.horizontal, ); } |
Now, we are ready to try this
As a result, you will get the 5 sliding cards on the center of your screen
