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#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.
This implements a DefaultFocusTraversal widget to describe the focus traversal policy for its children, defined by a FocusTraversalPolicy object from which custom policies may be created. Pre-defined policies include widget-order traversal, "reading order" traversal and directional traversal.
This re-lands the Focus changes in #30040. Correctness changes in routes.dart, and removes the automatic requesting of focus on reparent when there is no current focus, which caused undesirable selections.
Addresses #11344, #1608, #13264, and #1678Fixes#30084Fixes#26704
Implements focus traversal for desktop platforms, including re-implementing the existing focus manager and focus tree.
This implements a Focus widget that can be put into a widget tree to allow input focus to be given to a particular part of a widget tree.
It incorporates with the existing FocusScope and FocusNode infrastructure, and has minimal breakage to the API, although FocusScope.reparentIfNeeded is removed, replaced by a call to FocusAttachment.reparent(), so this is a breaking change:
FocusScopeNodes must now be attached to the focus tree using FocusScopeNode.attach, which takes a context and an optional onKey callback, and returns a FocusAttachment that should be kept by the widget that hosts the FocusScopeNode. This is necessary because of the need to make sure that the focus tree reflects the widget hierarchy.
Callers that used to call FocusScope(context).reparentIfNeeded in their build method will call reparent on a FocusAttachment instead, which they will obtain by calling FocusScopeNode.attach in their initState method. Widgets that own FocusNodes will need to call dispose on the focus node in their dispose method.

This fixes the assumption that InputDecorator had where it expected baseStyle to be a complete style. Now it merges the baseStyle with the subhead style instead of substituting it entirely.
This fixes#12832.
This adds an optional character counter and maxLength parameter to the TextField, as described in the Material Design Spec.
The counter text and style in the input decorator may be specified, but will default to the "right thing" if not specified, where the "right thing" is a counter that looks like "3 / 10" (if there are three characters entered into a field where maxLength is set to 10).
To limit the number of characters entered, I created a LengthLimitingTextFormatter that will limit the number of characters (Unicode runes) in the input, which can be used independently. The formatter is applied after the other formatters supplied (if any). Even if there is no decorator, the text field will limit the number of characters input if maxLength is set.
If maxLengthEnforced is set to false (it defaults to true), then the max length will not be enforced. In that case, if the text exceeds the length, then the counter will turn red, and it will make the divider turn red.
* Theme provides all TextStyle properties
* match field declaration order in the test
* Theme.of returns text style with inherit == false
* change TextStyle.inherit logic; docs
* add TextStyle.debugLabel
* address comments
* add debug labels to Typography text styles
Correctly handle the case where the TextEditingController associated
with a TextField is set to null. Due to a typo (= vs ==), previously
this was a no-op and the existing TextEditingController was retained,
rather than copied.
* Introduce a Directionality inherited widget which sets the ambient LTR vs RTL mode (defaulting to null, which means you cannot use directionality-influenced values).
* Make it possible to configure Padding (including Container.padding and Container.margin) using a directionality-agnostic EdgeInsets variant.
* Provide textDirection and verticalDirection controls on Row and Column to make them RTL-aware.
* Introduce a variant of FractionalOffset based on the EdgeInsets variant. Not yet actually used.
* Fix all the tests that depended on Row defaulting to LTR.
Introduce CompositedTransformTarget and CompositedTransformFollower
widgets, corresponding render objects, and corresponding layers.
Adjust the way text fields work to use this.
Various changes I needed to debug the issues that came up.
* Add a text formatter interface used by EditingText. Provide some default implementations.
* self nits
* Handle -1 selection offsets
* review notes
* simplify regular expression
* Add whitelisting formatters. Use a custom phone number formatter in text demo.
* review notes
* not being able to addAll(null) is pretty annoying
* review notes
* partial tests
* Add tests
* didn’t end up needing mockito
* move to services
* 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
Fixes a bug where tapping in the text under edit moved the cursor but
did not push the updated selection to the engine.
Adds a test for caret position updates.
We should always use the maxWidth from the incomming constraints to size the
text inside the editable because the EditableText itself always expands to fill
its width.
Also, make sure InputDecoration always expands horizontially (even when there's
no icon) for consistency.
Fixes#9149
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
