In this Flutter post, we will be implementing Flutter carousel slider full width and explain it step by step with the help of a proper Flutter example. Everything about implementing Flutter carousel slider full width will be discussed in detail so you can easily set Flutter carousel slider full width in your own Flutter apps.
What is Flutter Carousel Slider Full Width?
It means that each item of Flutter carousel slider should have a full width. We will see what the default width of slider items are. Then we will change it to Flutter carousel slider full width.
Default Flutter Carousel Slider Items Width
To see the default width of Flutter carouse slider items, we have to define a simple Flutter carousel slider.
We first have to import the carousel slider package in our pubspec.yaml file, then we can use it. If you want to learn how to import that package then click here.
We have created a list of colors. They will be used to give different color to each item of carousel slider. The items constructor of Flutter carousel slider is used to show items in the carousel slider. For demonstration, we will use a Flutter container widget with a child text widget. Each container will have a different color. See the below code for practical understanding.
List itemColors = [Colors.green, Colors.purple, Colors.blue];
SizedBox( height: 200, width: double.infinity, child: CarouselSlider( items: [ for (int i = 0; i < itemColors.length; i++) Container( color: itemColors[i], alignment: Alignment.center, child: Text( 'Item $i', style: TextStyle(color: Colors.white, fontSize: 20), ), ) ], options: CarouselOptions( autoPlay: true, autoPlayInterval: Duration(seconds: 3)), ), )
Implementing Flutter Carousel Slider Full Width
For that, we have to use the options constructor of Flutter carousel slider. It takes carousel options and by using its view port fraction constructor, we can easily set the full width of carousel items. This constructor takes a double(decimal value) but we can also pass integer to it.
For demonstration, we will pass 1 to that constructor. See the below code:
options: CarouselOptions( viewportFraction: 1 )
You can see that the Flutter carousel slider full width is successfully implemented. Hope you now will set full width of Flutter carousel slider items in your Flutter apps with ease. I would be glad to answer your questions regarding the implementation of Flutter carousel slider full width, if you still have any.
Below section has the complete source code in which Flutter carousel slider full width is also implemented.
Flutter Carousel Slider Full Width Implementation Source Code
import 'package:carousel_slider/carousel_slider.dart';
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Homepage(),
);
}
}
class Homepage extends StatelessWidget {
List itemColors = [Colors.green, Colors.purple, Colors.blue];
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
body: Center(
child: SizedBox(
height: 200,
width: double.infinity,
child: CarouselSlider(
items: [
for (int i = 0; i < itemColors.length; i++)
Container(
color: itemColors[i],
alignment: Alignment.center,
child: Text(
'Flutter Carousel Slider Full Width Items',
style: TextStyle(color: Colors.white, fontSize: 20),
),
)
],
options: CarouselOptions(
viewportFraction: 1,
autoPlay: true,
autoPlayInterval: Duration(seconds: 3)),
),
),
),
));
}
}Conclusion
