This implements the keyboard shortcut handling and action invocation in order to provide a place in the infrastructure for keyboard events to trigger actions. This will allow binding of key events to actions like "move the focus to the next widget" and "activate button".
This adds a list of key synonyms for non-printable keyboard keys that appear in more than one place So keys like LogicalKeyboardKey.shiftLeft and LogicalKeyboardKey.shiftRight now can be mapped to just LogicalKeyboardKey.shift.
I also fixed a bug in the gen_keycodes tool where GLFW entries would get removed if they weren't parsed from the source on the web.
- A refactor that moves the semantics declaration from detectors to recognizers to allow custom recognizers to respond to semantic gectures.
- Renames all handlers related to semantics from Gesture* to Semantics*.
This updates FadeInImage to use the new Image.frameBuilder
API (added in #33369), to greatly simplify the implementation
of FadeInImage.
This also removes the FadeInImage.placeholderSemanticLabel property.
This property was added in #28799 for the sake of completeness (the bug
it fixed was the lack of any semantic label support in FadeInImage), but a
placeholder is a transient visual artifact, not something that affects the
underlying semantic meaning of the image.
Tickers being disabled and re-enabled can cause the
condition of a synchronous notification happening after
image frames have been delivered, which is valid in that
case. As such, this removes the assert.

This adds DiagnosticableMixin as a mixin class that provides the implementaion for Diagnosticable, so that we can now add diagnostics to classes which already have a base class.
This PR solves two problems: currently, the onExit is called for a mouse pointer the moment the removal message is received, except that by the time it actually calls it, there is no _lastEvent for it in the mouse tracker (it's already been removed), resulting in an event being passed to the onExit that contains nulls for the position. Also, removePointer events don't actually get created with a position, although they easily could be, so that even the the _lastEvent in the mouse tracker were still populated, it would still give a null position and delta.
This PR adds support for the position and delta in a PointerRemovedEvent, and populates them. In addition, when a remove event is received, it doesn't actually remove the pointer until the mouse position check that gets scheduled actually happens.
- Fixed extentInside calculation in ScrollMetrics
- Added asserts to extentInside getter, as well as ScrollPosition.applyContentDimensions to enforce minScrollExtent <= maxScrollExtent
- Added padding to ScrollbarPainter, updated implementation. Took care of some edge cases.
- Changed some scroll bar constants on Cupertino side.
This adds two new builders to the `Image` class:
* `frameBuilder`, which allows callers to control the widget
created by an [Image].
* `loadingBuilder`, which allows callers fine-grained control
over how to display loading progress of an image to the user.
`FadeInImage` can be simplified by migrating to the new API.
This is done in a follow-on commit.

* Deprecates `BinaryMessages` in favor of a default instance of `BinaryMessenger`, called `defaultBinaryMessenger`
* Platform channels use the `defaultBinaryMessenger` for their binaryMessenger default argument.
