FadeInImage in Flutter

Updated 28 April 2023


A FadeInImage works with images of any type: in-memory, local assets, or images from the internet.

Use FadeInImage class to display long-loading images, such as NetworkImage.new, so that the image appears on screen with a graceful animation rather than abruptly popping onto the screen.

You may also check our Flutter app development company page.

To implement the FadeInImage do follow the steps mentioned below.

1.) Create a Scaffold.

2.) Create the FadeInImage as you desire.

3.) Use the transparent_image package for a simple transparent placeholder.

1.) Create a Scaffold. :

Inside Scaffold widgets, it Implements the basic material design visual layout structure. First, initialize the main app as a stateless widget.

This class provides APIs for showing drawers and bottom sheets. We can add the background color inside the scaffold widget.

It also supports special Material Design components, such as Drawers, AppBars, and SnackBars.

2.) Create the FadeInImage as you desire.

Now, use to create a FadeInImage in the flutter we have to call the constructor of the FadeInImage class provided by the flutter.

3.) Use the transparent_image package for a simple transparent placeholder.

If the image emits an ImageInfo synchronously, such as when the image has been loaded and cached, the image is displayed immediately, and the placeholder is never displayed.

When the placeholder changes and the image has not yet emitted an ImageInfo, then the placeholder is resolved to a new ImageStream. If the new ImageStream.key is different, this widget subscribes to the new stream and replaces the displayed image with images emitted by the new stream.

The full code is mentioned below.

We can now run the app on how to create FadeInImage in a flutter.

Finally, we have implemented the flow of creating FadeInImage in a flutter.

Hope this blog helps you to create FadeInImage in a flutter.

So, I hope it will help you out in understanding and get a brief idea about it.
