Replacing the algorithm for finding the first focusable item in the focus tree. Somehow it was a kind of gibberish before, and really didn't work or make sense.
Updates documentation and non-public API to use American spellings for
consistency with the rest of the codebase.
No changes to behaviour... other than how it's spelt.
* Implement ExpandIcon custom color, expandedColor, and disabledColor
* Update to use pumpAndSettle instead of hard-coded duration
* Update colors to unfocused state, added dark mode test to active state
* Fix Colors.white30 doc opacity value
* Add links to Material Design specifications to color, expandedColor and disabledColor
* Update API docs to reference dark theme material page
This is another step towards supporting image loading
progress notification at the widgets layer.
This adds an `ImageChunkEvent` class along with associated
`ImageChunkListener` callback signature and an `onChunk`
property to `ImageStreamListener`. The events serve to
notify registered listeners when byte chunks are received
while loading an image.

This just fixes up some comments for DefaultFocusTraversal, and fixes a minor bug when setting the onKey on a FocusNode on creation before attaching to it.
The current API was broken in that you registered multiple
callbacks at once, but when you removed listeners, only the
primary listener was used to determine what was removed.
This led to unintuitive cases where the caller could get
unexpected behavior.
This updates the API to add and remove listeners using
a newly introduced [ImageStreamListener] object, a value
object that has references to the individual callbacks
that may fire.

Resets the enabled color for outline text field default borders to "On Surface 38%" instead of "On Surface 12%" to match spec. Also fixes the hover overlay to be "On Surface 12%" to match spec.
This will allow us to plumb the chunks in a chunked response
up to the higher levels of the framework to notify interested
parties of network loading progress.

Currently, the fact that NetworkImage uses a static HttpClient
makes it impossible to properly test, as a mock in one test will
be reused in another test. This change fixes that.

This adds support for an animated focusColor and hoverColor to InputDecorator. This color will blend with the background over a fade in period whenever the InputDecorator is focused or hovered, respectively.
It also adds a Listener to the TextField to listen for hover events.
Until this change, Focus.of would return a FocusScopeNode if it found a FocusScope widget. This isn't really all that useful, and can easily lead to bad situations where many widgets think that the scope they are in (or the root scope!) is their indication of being focused.
This changes Focus.of to throw an exception if it doesn't find a Focus widget before reaching the nearest FocusScope widget, or the root of the widget hierarchy.
It also adds a nullOk optional bool to Focus.of so that if a caller expects to not find a Focus widget, it can deal with that as it sees fit. I modified InkWell to use this new behavior.
This fixes an unreported issue that widgets using an InkWell will be drawn as focused the first time they are visited.
This adds a reverseDuration parameter to AnimationController so that the animation has a different duration when going in reverse as it does going forward.
Date picker tests have been flaky on Windows for a long time, and repeatedly require restarting of bots. In the interest of productivity, disabling them on Windows.
Related to #19696
The PlatformViewsService listens for `viewFocused` calls on the
platform_views system channel and fires a callback that focuses the
focus node for the relevant AndroidView widget.
This implements focus and hover handling for Material buttons. It inserts Focus widgets into the tree in order to allow buttons to be focusable via keyboard traversal (a.k.a. TAB traversal), and Listener widgets into the InkWell to allow the detection of hover states for widgets.
Addresses #11344, #1608, and #13264.
This fixes propagation of needsCompositing from child widgets.
When needsCompositing is turned on by a child widget, it necessarily sets the needsCompositing bit of its parent widget, but RenderPointerListener was ignoring that piece of information and only turning on compositing if it thought it needed it for itself.
This corrects that, and adds a test for the condition, and updates a test that was affected by the change.
Fixes#32525 (again)
This fixes#32525, because it now marks the compositing bits as needing to be recalculated if the mouse tracker changes its idea of whether or not a mouse is attached.
This bug occurred because the test framework was leaking state from one test to the next (the state about whether a mouse pointer was active), and so even though there was a "passing" test when run in order with the other tests in the file, when the test was run individually (or first), it would have failed and caught the bug.
This adds an assert to make sure that after each test there are no simulated mouse pointers connected, and now calls removePointer in all of the tests where this was a problem.
