What is a sliver flutter?

In Flutter, a sliver is a slice of a scrollable area you can use to achieve custom scrolling behaviors.

It consists of displaying an image or background in the upper part of the screen, occupying a fixed space, so that later, by scrolling upwards, the content changes and becomes a navigation bar in iOS or toolbar in the case of Android. …

The SliverList widget takes in a delegate where you provide the list of items you want to show. Here, you can use SliverChildListDelegate if you want to show a predefined list of widgets or you can choose to build your items lazily with SliverChildBuilderDelegate.
