Displaying a network image in a Flutter application is a common task, and there are multiple ways to achieve it. In this article, we will show you how to display a network image using the Flutter framework and a third-party library.
First, let’s take a look at how to display a network image using the Flutter framework. The most straightforward way to do this is to use the Image.network()
widget. This widget takes a single argument, the URL of the image you want to display. Here is an example of how to use it:
Copy codeImage.network(

height: 300,
width: 300,
fit: BoxFit.cover,
)
The height
, width
, and fit
arguments are optional. They allow you to set the size and fitting of the image. In this example, we set the height and width to 300 pixels and set the fit to BoxFit.cover
to fill the entire container.
Now, let’s take a look at how to display a network image using a third-party library. A popular library for displaying network images in Flutter is cached_network_image
. This library allows you to cache images and provides a CachedNetworkImage
widget that you can use to display network images. To use this library, you first need to add it to your pubspec.yaml
file and run flutter packages get
. Here is an example of how to use it:
Copy codeCachedNetworkImage(

height: 300,
width: 300,
fit: BoxFit.cover,
)
As you can see, the CachedNetworkImage
widget works in a similar way to the Image.network()
widget. It takes the same arguments and allows you to set the size and fitting of the image. The main difference is that this widget caches the image, so that it is faster to load when the user navigates back to the image.
In conclusion, displaying a network image in a Flutter application is a simple task that can be achieved using either the Flutter framework or a third-party library. By using Image.network()
widget or cached_network_image
package, you can easily display network images in your app.
