* 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.
We were trying to cram too much functionality in to the Dialog widget. Now we
have AlertDialog and SimpleDialog to cover to two different kinds of dialogs in
the spec.
Rather than scrolling the entire contents of the dialog, we should instead
scroll only the part between the title and the button bar.
Also, polish up the padding in the simple dialog demo.
Fixes#6057
The code previously assumed that paint would be called before hitTest, but that
assumption isn't valid because RenderOpacity hit tests its children without
painting them.
Fixes#6089
The spec forbids persistent bottom sheets from overlapping the app bar. There
are also some fancy scroll-linked effects that we're supposed to do with
persistent bottom sheets, but those will need to wait for another patch.
Fixes#5143
Previously, we were getting double padding: both inside and outside the button.
This patch moves all the padding inside the button so that the whole region is
hittable and the text is positioned correctly.
Fixes#6059
This requires all AnimationController objects to be given a
TickerProvider, a class that can create the Ticker.
It also provides some nice mixins for people who want to have their
State provide a TickerProvider. And a schedulerTickerProvider for those
cases where you just want to see your battery burn.
Also, we now enforce destruction order for elements.
This silences an assertion that fired when reparenting a widget with a
global key inside a LayoutBuilder callback when that callback also
happened to call setState (directly or indirectly) on that widget.
Normally such setStates are considered ok since we know we haven't
cleaned that subtree yet, but we were not correctly handling the case
where the list needed resorting in that situation.
This structure for the API is hopefully less confusing that the previous one
(which implied that vertical drags would not trigger horizontally draggable
widgets).
Fixes#1987
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.
It wasn't taking padding into account when deciding which children were
visible. I modeled the solution off of the way ScrollableList handles
this.

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
Changed MergableMaterial to animated between states that have dividers
and those that don't in order not to have dividers that appear
unanimatedly. Fixes#5847.
