ContentPlaceholder class
A widget that creates a placeholder for content.
The ContentPlaceholder widget can be used to create a placeholder for your content
while it is being loaded or fetched asynchronously. It can be used with or without
a child widget. If a child widget is provided, the placeholder will overlay the child
with a shimmer effect, otherwise, it will create a standalone placeholder block.
