Differences between SliverList vs ListView in Flutter

Solution 1:

There's almost no difference.

ListView is a SliverList. Same with GridView, which is a SliverGrid.

They are doing exactly the same thing. The only difference between them is that SliverList is a sliver, not a widget. Which means it's used inside a ScrollView, usually CustomScrollView.

ListView is nothing else but a biding of SliverList to transform it into a Widget to make it usable alongside other widgets such as Row/Container.

Most of the time, use ListView.

But if you want advanced scroll behavior such as appbar animations with scroll ; you'll need to use a CustomScrollView. Which will force you to use SliverList instead of ListView.

Solution 2:

According this article,

All of the scrollable views you use, like ListView and GridView, are actually implemented using Slivers. You can kind of think of Slivers as a lower-level interface, providing finer-grained control on implementing scrollable area. Because slivers can lazily build each item just as it scrolls into view, slivers are particularly useful for efficiently scrolling through large numbers of children.
