Since RelativeRect's whole purpose in life is to make work with Stack
easier, it's silly that you can't directly use it with Positioned.
Also, tests for RelativeRect.
And fixes for the bugs that found...
This patch adds grid supports to slivers and introduces a ScrollGrid
convenience class for making the common types of scrollable grids.
This patch also deploys ScrollGrid in an example in the Flutter Gallery.
Add SliverList
A SliverList is a linear layout of box children in a viewport that all
have a common, fixed extent along the scroll axis. The layout is similar
to a SliverBlock but more efficient.
I plan to use this to implement similar logic in SliverPadding.
To make this easier to test I extended the paints matcher to accept a
function that takes a canvas. While I was at it I also made it accept
a Finder, it'll go and find the render object for you.
Also added support for paints..path and fixed some grammar in the
error messages.
Also improved the docs for debugPaint*.
This widget is a replacement for ScrollableViewport that uses the new
Scrollable2 machinery. The widget is not based on Slivers but does use the new
scroll behavior classes.
MockCanvas to use it instead.
Currently it only supports a very limited set of drawing features, but
adding new ones is easy.
Once the feature set is more complete, and we've used this a bunch, if
it feels right, this API will get promoted to flutter_test.
This patch changes the default appearance of Slider to not have the
thumb be an open circle at its minimum position. The `thumbOpenAtMin`
property can enable drawing an open thumb at the min position, which was
the previous behavior.
Fixes#6941
More idiomatic use of constraints in performResize.
Trivial fixes to comments.
Make ProxyBox not use BoxParentData since it ignores the field.
Make applyPaintTransform more helpful if you use a different ParentData
subclass than RenderBox expects.
Make debugAssertIsValid actually fulfill its contract in RenderObject as
documented.
Add a childBefore for symmetry (we already had childAfter).
Fix the way we dump the child list when there's no children in a
multichild render object.
More asserts in the rendering test library.
* globalToLocal was just broken when there was a rotation and a
translation at the same time. This fixes that and adds a test.
* update graphic used by spinning_mixed since the old one went 404.
* simplify some of the code in the demo.
* fix MatrixUtils.transformPoint to be consistent with how we transform
points elsewhere.
* stop transforming points elsewhere, just use
MatrixUtils.transformPoint.
* make the Widget binding handle not having a root element.
* make the spinning_mixed demo update its widget tree.
This rewrites imports of various mojom.dart files from the Flutter
engine repo to instead import normal-looking dart files from the
(new) flutter_services package. This package handles exporting the
correct symbols from generated code wherever that may live.
Includes an engine roll to 3551e7a48e2e336777b15c7637af92fd7605b6c5
which contains the new flutter_services package.
This property now applies only to the free space in the flex layout (i.e.,
minimize or maximize the amount of free space). Previously, the flexible
children were always allocated a size of zero when MainAxisSize was min. Now
they're allocated the same size that would be if the MainAxisSize was max.
Previously, flexible children were always required to fill their allocated
space. After this change, they can fit loosely into that space and not fill it.
When that happens, the remaining free space is allocated according to the
maixAxisAlignment.
Fixes#5858
