How To Easily Set Flutter Carousel Slider Full Width

flutter carousel slider full width

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)),
          ),
        )

You can see that we have specified the height and width of the Flutter carousel slide by wrapping it with Flutter sized box widget and giving that sized box widget some height and width. The default Flutter carousel items width can be seen in the above image.
Let’s now see how to set it to Flutter carousel slider full width.

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
            )
