In the article, I will discuss, how to Implement placeholder images in the custom image widget.

For this, I will use FadeInImage widget to handle placeholder images. This FadeInImage widget, displays a placeholder image before requesting an image from the internet. To know more about FadeInImage please click here.

Let’s start with the implementation part.

Firstly, I create an ImageView widget that accepts the URL and build the FadeInImage widget.

Here i have use 2 extra params that accept image height and width which manage image according to the given size.

You can also use the memoryNetwork to access transparent_image package.This package exports one constant: kTransparentImage which is a simple transparent image. To know more about transparent_image package please click here.

Now call this imageview widget in code where we want to show image.

Here is the output:
