PinnedHeaderSliver ( #143196 )
...
A sliver that remains âpinnedâ to the top of the scroll view. Subsequent slivers scroll behind it. Typically the sliver is created as the first item in the list however it can be inserted anywhere and it will always stop at the top of the scroll view. When the scrolling axis is vertical, the PinnedHeaderSliverâs height is defined by its widget child. Multiple PinnedHeaderSlivers will layout one after the other, once they've scrolled to the top.
This sliver is preferable to the general purpose SliverPersistentHeader - for its relatively narrow use case - because there's no need to create a [SliverPersistentHeaderDelegate] or to predict the header's size.
Here's a [working demo in DartPad](https://dartpad.dev/?id=3b3f24c14fa201f752407a21ca9c9456 ).

SliverResizingHeader ( #143325 )
...
A sliver that is pinned to the start of its `CustomScrollView` and reacts to scrolling by resizing between the intrinsic sizes of its min and max extent prototypes.
The minimum and maximum sizes of this sliver are defined by `minExtentPrototype` and `maxExtentPrototype`, a pair of widgets that are laid out once. You can use `SizedBox` widgets to define the size limits.
This sliver is preferable to the general purpose `SliverPersistentHeader` for its relatively narrow use case because there's no need to create a `SliverPersistentHeaderDelegate` or to predict the header's minimum or maximum size.
The sample shows how this sliver's two extent prototype properties can be used to create a resizing header whose minimum and maximum sizes match small and large configurations of the same header widget.

DecoratedSliver ( #127823 )
...
This is a second attempt to merge #107269 . Currently I've fixed two of the issues:
1. Fixed horizontal scrollview by using a switch statement to consider vertical/horizontal case.
2. Fixed issue of `paintExtent` not being the right extent for painting. Rather using a `scrollExtent` for the main axis length of the decoration box and painting it offsetted by the `scrollOffset`.
3. If the sliver child has inifinite scrollExtent, then we only draw the decoration down to the bottom of the `cacheExtent`. The developer is expected to ensure that the border does not creep up above the cache area.
This PR includes a test that checks that the correct rectangle is drawn at a certain scrollOffset for both the horizontal and vertical case which should be sufficient for checking that `SliverDecoration` works properly now.
Fixes https://github.com/flutter/flutter/issues/107498 .

Sliver Main Axis Group ( #126596 )
...
This widget implements the ability to place slivers one after another in
a single ScrollView in a way that all child slivers are drawn within the
bounds of the group itself (i.e. SliverPersistentHeaders aren't drawn
outside of the scroll extent provided by all of the child slivers). The
design document for SliverMainAxisGroup can be found
[here](https://docs.google.com/document/d/1e2bdLSYV_Dq2h8aHpF8mda67aOmZocPiMyjCcTTZhTg/edit?resourcekey=0-Xj2X2XA3CAFae22Sv3hAiA ).
Fixes https://github.com/flutter/flutter/issues/33137 .
