* 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
We used to use this mechanism to paint scrollbars, but it's awkward. The
new approach to scrollbars is much cleaner. This mechanism has no other
clients, so we should remove it.
This makes it possible to substitute 'flutter run' for 'flutter test'
and actually watch a test run on a device.
For any test that depends on flutter_test:
1. Remove any import of 'package:test/test.dart'.
2. Replace `testWidgets('...', (WidgetTester tester) {`
with `testWidgets('...', (WidgetTester tester) async {`
3. Add an "await" in front of calls to any of the following:
* tap()
* tapAt()
* fling()
* flingFrom()
* scroll()
* scrollAt()
* pump()
* pumpWidget()
4. Replace any calls to `tester.flushMicrotasks()` with calls to
`await tester.idle()`.
There's a guarding API that you can use, if you have particularly
complicated tests, to get better error messages. Search for
TestAsyncUtils.
Turns out a common use for Baseline is making sure that the child's
baseline is higher than it otherwise would be, e.g. with the Material
font or other symbols.
+ Add new demo to gallery to show data tables. (This currently doesn't
use a Card; I'll create a Card version in a subsequent patch.)
+ Fix checkbox alignment. It now centers in its box regardless.
+ Add Colors.black54.
+ Some minor fixes to dartdocs.
+ DataTable, DataColumn, DataRow, DataCell
+ RowInkWell
+ Augment dartdocs of materia/debug.dart.
+ DropDownButtonHideUnderline to hide the underline in a drop-down when
used in a DataTable.
+ Add new capabilities to InkResponse to support RowInkWell.
+ Augment dartdocs of materia/material.dart.
+ Add an assert to catch nested Blocks.
+ Fix a crash in RenderBox when you remove an object and an ancestor
used its baseline. (https://github.com/flutter/flutter/issues/2874)
+ Fix (and redocument) RenderBaseline/Baseline.
+ Add flex support to IntrinsicColumnWidth.
+ Document more stuff on the RenderTable side.
+ Fix a bug with parentData handling on RenderTable children.
+ Completely rewrite the column width computations. The old logic made
no sense at all.
+ Add dartdocs to widgets/debug.dart.
+ Add a toString for TableRow.
If two repaint boundaries mark themselves dirty, but the second one is a
child of the first, then the second one will get repainted by the first
and then when we come to paint it directly, we get confused because it
isn't dirty any more.
We ran into this in layout before. Apply the same fix. Also, apply the
same fix to composition while we're at it.
I ran into a case where I was setting minHeight=∞ and then calling
layout() with that constraint, which is all kinds of bad. To try to
catch this earlier, this patch now provides a way to catch constraints
that are requiring infinite values.
We don't _always_ check this because there are valid uses for
BoxConstraints.biggest, e.g. as an additionalConstraint.
Previously this was used by MixedViewport, but now we don't need it because
LazyBlockViewport has replaced MixedViewport.
I've also taken this opportunity to modernize RenderBlock.
- Add x and y to the parent data, in case it's useful. In point of fact,
I ended up not needing it.
- Make columnWidths settable rather than having a setter so that the
code in the widgets layer is more idiomatic.
- Teach setFlatChildren about avoiding unnecessary drop/adopt loops.
- Assert that the child list length is correct more aggressively so that
we catch the dumb bug I had more quickly next time.
- Improve the toString() to handle empty tables better.
- Resort the imports in framework.dart.
- Introduce a LocalKey for cases where you don't want to allow use of
GlobalKey.
- Make inflateWidget and deactivateChild public for subclass use.
- Table widget.
- Cell widget.
- TableRow fake widget.
New RenderAligningShiftedBox abstract class for render boxes with
"alignment", which as of now is:
- RenderPositionedBox
- RenderConstrainedOverflowBox (ex RenderOverflowBox)
- RenderSizedOverflowBox
- RenderFractionallySizedOverflowBox (ex RenderFractionallySizedBox)
(The respective widgets are Align, OverflowBox, SizedOverflowBox, and
FractionallySizedBox. They haven't been renamed.)
Also I added some toString details.
This reverts commit f41b3411da35929b09009e47cb52474389e42874, reversing
changes made to e33d8d96212f3e337a6660f1eb1118bffc945bf5.
This was a bad check-in due to my mangling uploading a new version of the branch from a different machine.
This reverts https://github.com/flutter/flutter/pull/2639 and will be replaced by https://github.com/flutter/flutter/pull/2640
