RawEditableLine is now responsible for the scrolling behavior, which
removes the need for callbacks between RawEditableLine and Input. It
also fixes a bug whereby the whole Input widget (including its icon)
would scroll when the text got long.
This patch restructures how we size the editing region of the Input widget. Now
RenderEditableLine understands that it's a single-line editing widget and sizes
itself correctly.
This patch removes Performance and AnimationValue now that we've ported the
framework over to AnimationController and Tween. This patch also cleans up the
names of the AnimationController classes now that they don't have to avoid
conflicts with the old animation API. Specifically, I've made the following
renames:
* Animated -> Animation
* Evaluatable -> Animatable
* PerformanceStatus -> AnimationStatus
This patch is just renames and moving code around. There aren't any changes in
behavior.
RenderBlock wasn't constraining the results.
RenderPadding wasn't constraining the results (which matters
especially when the constraints can't fit the padding in the first
place).
RenderViewport wasn't constraining the results.
Add a test for the block case.
To catch this kind of thing in the future, add some asserts to
debugDoesMeetConstraints() that all four intrinsic functions return
values that are within the constraints.
RenderBlockViewport doesn't support returning intrinsics, so turn off
the "no intrinsic support" asserts (and return zero) when we're doing
this new assert.
This new assert screwed up the custom layout classes' tests, so adjust
those tests to ignore the callbacks invoked from these asserts.
Add to the _debugReportException() method a short summary of the
descendants of this node. It's important to have this information when
debugging errors like these intrinsic constraints contract violations
because often nodes just pass the values through to their child so you
have to go several steps down to find the actual problem.

Introduces a new Tooltip class.
Adds support for tooltips to IconButton and Scaffold.
Adds some tooltips to various demos.
Also some tweaks to stack.dart that I made before I decided not to go
down a "CustomPositioned" route.
The pointer router was using an iteration pattern that always delivers
handleEvent calls even if you remove a route during the iteration.
That's awkward to program against and causes trouble for the double-tap
gesture.
This patch switches PointerRouter to using a re-entrant iteration
pattern that supports removing routes (but not adding routes) during the
iteration.
This makes it more consistent with tightFor(), and also makes it
easier to tighten both directions at once when you're not sure you
will always do so (e.g. if you have a height and width that might be
null, and want to tighten whichever ones aren't null).
This patch also changed ScrollableList2 to use an Iterable instead of an
List for its children. This change lets clients map their underlying
data lazily. If the clients actually have a concrete list, we skip the
extra copy and grab the child list directly.
This patch make grid layout much more flexible. The behavior is factored
out into a GridDelegate that's modeled after the custom layout
delegates. The patch includes a MaxTileWidthGridDelegate that implements
the old behavior and a FixedColumnCountGridDelegate that implements a
grid layout with a fixed number of columns.
Fixes#1048
When assigning a new overlayPainter, we were detaching the old overlay
painter even if the render object itself wasn't attached. Now we only
twiddle the attach/detach state of the overlay painter when we're
attached ourselves.
Fixes#1047
Require a Key on Input.
Simplify the API for Focus.at() and Focus.moveTo().
Fixes#236.
This will require an e-mail to flutter-dev.
Make Input grab focus onTap not onPointerDown.
Fixes#189.
Complain when you use Focus.at() with two different GlobalKeys that
are both in the tree at the same time.
Fixes#181.
Add dartdocs for Focus.moveTo() and Focus.moveScopeTo().
- Add RenderFractionalTranslation, a render box that does a
translation based on a FractionalOffset.
- Make FractionalOffset more like Offset
- dx/dy instead of x/y
- add /, ~/, %
- add .zero
- Add alongOffset and alongSize to FractionalOffset so that you can
easily apply FractionalOffset to Offsets and Sizes. (Better name
suggestions welcome.)
- Add transformHitTests boolean to RenderTransform (also on
RenderFractionalTranslation), and to classes based on it.
- Remove the fade from Dismissable. We can add it back using the
builder-with-child pattern like Draggable if we need it. See #1003
for tha feature request.
- Rename a bunch of variables in dismissable.dart.
- Change the test for dismissable to not handle leftwards dismisses
one pixel different from rightwards dismisses, and cleaned up the
resulting effect on the test (mostly making sure we had the right
number of pumps, with comments explaining what each one was).
Fixes#174.
Use the same technique for updating compositing bits as layout and
painting. This avoids walking the entire rendering tree when all you
need to update is a small subtree.
The TabBarSelection change animation needs to start where the fling's drag gesture ended rather than from zero. The intial vlaue of progress for the TabBarSelection's performance is now converted from the range used during an interactive drag, to the range used when animating from the previously selected tab to the new one.
TabBarSelection now requires a maxIndex parameter.
