Yes, I have read the documentation. But didn't find any differences. That is why I asked about it. – Rafiqul Hasan May 16 '18 at 10:15

@Pascal This question was asked in 16 may, 2018. In that time flutter was in alpha stage. There was not much of documentation or article to find. – Rafiqul Hasan Jan 20 '20 at 06:28

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.

1with `SliverList` it's possible to use `SliverToBoxAdapter`, is there any equivalent for `ListView` which is not inside a sliver list ? – Pars Feb 11 '19 at 15:10

According this article,
All of the scrollable views you use, like
ListViewandGridView, areactually 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.
