Also:
* Add three explicit sizing modes to Stack for non-positioned
children: loose, expand, and passthrough. (All three are used.)
* Fix a bug whereby layers would try to paint in the same frame as
they were removed from layout (but not detached).
* Fix a bug whereby Offstage wasn't properly marking the parent dirty
when changing its sizedByParent flag.
* Explicitly make Overlay expand non-positioned children.
* Explicitly have InputDecoration pass through the constraints from
its Row to its Stack children.
This patch reworks some of the guts of scrolling to make it easier to
implement nested scrolling effects. The actually nested scrolling effect
will be included in a later patch.
* Make Cupertino page transition elevation animated too
* Rename and change physical model to a decorated box
* Tests
* Add a comment
* still need to handle null in the tween somewhere
* nits
* Tweens evaluate to the actual begin/end instances. Let them be non-null
* Rename no decoration to none
With this patch, you can do:
```dart
Future<Null> foo() async {
try {
await controller.forward().orCancel;
await controller.reverse().orCancel;
await controller.forward().orCancel;
} on TickerCanceled {
// did not complete
}
}
```
...in a State's async method, and so long as you dispose of the
controller properly in your dispose, you'll have a nice way of doing
animations in sequence without leaking the controller. try/finally
works as well, if you need to allocate resources and discard them when
canceled.
Simultaneously, you can do:
```dart
Future<Null> foo() async {
await controller.forward().orCancel;
await controller.reverse().orCancel;
await controller.forward().orCancel;
}
```
...and have the same effect, where the method will just silently hang
(and get GC'ed) if the widget is disposed, without leaking anything,
if you don't need to catch the controller being killed.
And all this, without spurious errors for uncaught exceptions on
controllers.
* Manually fix every use of Point.x and Point.y
Some of these were moved to dx/dy, but not all.
* Manually convert uses of the old gradient API
* Remove old reference to Point.
* Mechanical changes

* Further improvements and a test
* Fix minor errors from rebasing...
* Roll engine
* Fix tests to use Ahem, and helpful changes around that
- Fix fonts that had metric-specific behaviours.
- LiveTestWidgetsFlutterBinding.allowAllFrames has been renamed
to LiveTestWidgetsFlutterBinding.framePolicy.
- LiveTestWidgetsFlutterBinding now defaults to using a frame policy
that pumps slightly more frames, to animate the pointer crosshairs.
- Added "flutter run --use-test-fonts" to enable Ahem on devices.
- Changed how idle() works to be more effective in live mode.
- Display the test name in live mode (unless ahem fonts are enabled).
- Added a toString to TextSelectionPoint.
- Style nit fixes.
* Roll engine to get Ahem changes.
* Update tests for dartdoc changes.
* Fix flutter_tools tests
Rename State.config to State.widget
Rename State.didUpdateConfig to State.didUpdateWidget
Renamed all State subclasses' local variables named config to something else
Fixes https://github.com/flutter/flutter/pull/8643
Fixes https://github.com/flutter/flutter/issues/8804 by adding a test
to verify that Material elevation changes animate.
Also tweak some dartdocs, add some trailing commas, improve some
toString output, make the inkwell test agnostic to the PhysicalModel
logic, and move the material buttons test to the material test
directory.
The Wrap widget is a layout that places children in a run in order along its
main axis until it runs out of space. At that point, starts placing children in
a new run that is adjacent in the cross axis.
Fixes#8831
This method seemed overly specific to the needs of one particular
subclass. This patch duplicates some code but makes the API conceptually
cleaner.

* Remove a space
* Review notes
* Remove the last deprecated test
After this patch, there are three major text input widgets:
* EditableText. This widget is a low-level editing control that
interacts with the IME and displays a blinking cursor.
* TextField. This widget is a Material Design text field, with all the
bells and whistles. It is highly configurable and can be reduced down
to a fairly simple control by setting its `decoration` property to
null.
* TextFormField. This widget is a FormField that wraps a TextField.
This patch also replaces the InputValue data model for these widgets
with a Listenable TextEditingController, which is much more flexible.
Fixes#7031
We now have an explicit focus tree that we manage. Instead of using
GlobalKeys to manage focus, we use FocusNode and FocusScopeNode objects.
The FocusNode is Listenable and notifies when its focus state changes.
Focus notifications trigger by tree mutations are now delayed by one
frame, which is necessary to handle certain complex tree mutations. In
the common case of focus changes being triggered by user input, the
focus notificiation still arives in the same frame.
This patch adds a notification to SliverChildDelegate that says which
children are alive after each layout. The delegate can use this
information to optimize it's underlying model of the children (e.g., by
discarding models for children that are far outside the live range).
