* Bump Dart SDK to `1.20.0-dev.10.0`.
`1.20.0-dev.10.0` corresponds to `1.20-RC0`.
* pubspec.lock cleanup
* check for pubspec.lock existence
* cleaned up conditional remove
This patch removes the Mozart dependencies from object.dart and
layer.dart, which will make it easier for us to move the Mozart
dependencies purely into the Fuchsia tree.
* 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.
Switch our pubspec.yamls to using SDK sources so that we can have consistent
source types when we depend on these packages from external packages using SDK
sources.
