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
If there's not enough height for the given aspect ratio, we now try to see if
using the height to infer the width will fit the given constraints. The
algorithm we use is similar to the one we use for RenderImage.
Fixes#2620
Transform applies its transform before painting, but sometimes you want
the widget to layout after its transform has been applied. We can't
handle general tranforms in this way because we can't couple width and
height constriants, but we can handle certain rotations.
Fixes#1214
We'll need this for RTL support because the RTL state will live in the widget
tree. Also, remove the `oldWidget` argument to updateRenderObject because there
aren't any clients for it.
Well, all the easy ones, anyway.
For some reason `// ignore:` isn't working for me so I've disabled
lints that need that. Also disabled those that require a ton of work
(which I'm doing, but not in this PR, to keep it reviewable).
This adds:
- avoid_init_to_null
- library_names
- package_api_docs
- package_names
- package_prefixed_library_names
- prefer_is_not_empty
- sort_constructors_first
- sort_unnamed_constructors_first
- unnecessary_getters_setters
Specifically:
* Handle null styles in TextSpan without crashing in toString().
* Handle null children in TextSpan child lists without crashing in
toString().
* Handle entirely empty TextSpans in toString() explicitly.
* Assert that TextSpans don't contain nulls in various places. This is
done more often than one might think necessary, because it turns out
that TextSpan takes a (mutable) List for one of its arguments, so
who knows what it will contain at any given time. By asserting all
over the place, hopefully we'll catch it near the change if they do
change it.
* Add a RichText example to Stocks to exercise RichText and TextSpans.

This patch prepares us to pass a BuildContext to RenderObjectWidgets, which
will make it possible to rebuild RenderObjectElements:
* Delay creation of the render object until mount(). That will let us pass
`this` to createRenderObject and have the inherited elements be initialized.
* Cleanup widgets that take builder closures to prepare for their
RenderObjectElement to be rebuilt more often.
* Add a test for the interaction between inherited widgets and
MixedViewport.
Related to #2598
After running a widget test, we now clear out the widget tree and check that we
didn't leak any timers or animations.
Also, fix several bugs that this addtional check revealed.
Fixes#2481
This patch tweaks the definition of max intrinsic size to give implementations
more wiggle room to compute there intrinsic sizes more efficiently.
Specifically, implementations can now ignore the incomming constraint in the
cross axis if they prefer.
This patch removes an assert that is no longer valid w.r.t. the new definition
of intrinsic sizing.
Fixes#2099
