DecoratedSliver #127823

thkim1011 · 2023-05-30T05:28:50Z

This is a second attempt to merge #107269. Currently I've fixed two of the issues:

Fixed horizontal scrollview by using a switch statement to consider vertical/horizontal case.
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.
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 #107498.

This reverts commit a02cd54.

I'd like to test this with the sliver group widgets once they land, that would make for a pretty great sample app to include here.

Also, looks like the analyzer is unhappy here.

Looks like the docs tests are failing since SliverDecoration was renamed but is still used throughout the docs.

+/// it is necessary to ensure that the bottom border does not creep
+/// above the top of the bottom cache.


What does this mean to the developer? Can you explain why/when this would happen?

Added an explanation on how this can happen.

Piinks · 2023-06-15T22:23:05Z

packages/flutter/lib/src/widgets/decorated_sliver.dart

+/// Commonly used with [BoxDecoration].
+///
+/// The [child] is not clipped. To clip a child to the shape of a particular
+/// [ShapeDecoration], consider using a [ClipPath] widget.


Does this mean users cannot provide a ShapeDecoration to DecoratedSliver.decoration? Or should not?

They could but it won't clip the contents of the child. I guess the developer should try to guarantee that the contents of the child fits within the decoration.
