To show an Sliding image in flutter you need to add a library called Carousel Pro using which you can easily add image slider widget in your project, to do so follow below steps.

Adding dependencies

Library may come with latest feature in future so better visit official site to know about the latest version.

Step 2: Importing the carousel pro package

Then once you have added the required library depencencies in you flutter project now you can make use of the library just by importing the package of carousel pro package wherever required.

import 'package:carousel_pro/carousel_pro.dart';

Step 3: Snipped code of image slider flutter example

Carousel(
       images: [
         AssetImage('assets/image1.jpg'),
         NetworkImage(
             'imageurl'),
         AssetImage("assets/image2.jpg"),
         NetworkImage(
             "https://image.shutterstock.com/image-photo/micro-peacock-feather-hd-imagebest-260nw-1127238584.jpg"),
         AssetImage("assets/image3.jpeg"),
         NetworkImage(
             'https://i.pinimg.com/originals/94/dd/57/94dd573e4b4de604ea7f33548da99fd6.jpg'),
       ],
     )

Then to show image slider we can make use of carousel widget that has a images[] properties where you can show any number of slidling images into the widget.

In the above snipped example i have make use of NetworkImage() widget to show images from internet, and AssetImage() to show images that are locally stored in Flutter project.

How to add assets and images in flutter Project

then to add image or assets under you flutter project you need to create a directory and name it as anything(in my case it assets).

Right click on your flutter project > New > Directory

give a name to you directory and there you go.

creating image assets directory in flutter

once assets directory is ready now you  specify the assets directory in pubspec.yaml file so that our flutter project can easily get to know where assets image are been loacted

Now once you have added the path then you can add some images into assets folder to use then in your dart code.

Let’s come back to our main motive about this project to show image slider in flutter app.
