I previously made a PR (#136140) that used `switch` expressions to make some parts of the Flutter codebase easier to understand. It was assigned to the framework team, and @christopherfujino let me know that it was too large to effectively review and recommended breaking it up into smaller pull requests.
Here's a PR that only targets files in the `dev/` directory. Hopefully this will be easier to work with!
(solves issue https://github.com/flutter/flutter/issues/136139)
## Description
This converts some usages of `RawKeyEvent` to `KeyEvent` to prepare the repo for deprecation of `RawKeyEvent`, and swaps out the `raw_keyboard.dart` manual test for `hardware_keyboard.dart`.
## Related Issues
- https://github.com/flutter/flutter/issues/136419
## Tests
- Just refactoring code, no semantic changes.
## Description
This modifies the `MenuAnchor` `onPressed` activation to delay until after the current frame is built, and resolve any focus changes before it invokes the `onPressed`, so that actions that operate on the `primaryFocus` can have a chance of working on the focused item they were meant to work on.
## Related Issues
- Fixes https://github.com/flutter/flutter/issues/118731
## Tests
- No tests yet (hence draft still)
Deprecate `textScaleFactor` in favor of `textScaler`, in preparation for Android 14 [Non-linear font scaling to 200%](https://developer.android.com/about/versions/14/features#non-linear-font-scaling). The `TextScaler` class can be moved to `dart:ui` in the future, if we decide to use the Android platform API or AndroidX to get the scaling curve instead of hard coding the curve in the framework.
I haven't put the Flutter version in the deprecation message so the analyzer checks are failing. Will do so after I finish the migration guide.
**Why `TextScaler.textScaleFactor`**
The author of a `TextScaler` subclass should provide a fallback `textScaleFactor`. By making `TextScaler` also contain the `textScaleFactor` information it also makes it easier to migrate: if a widget overrides `MediaQueryData.textScaler` in the tree, for unmigrated widgets in the subtree it would also have to override `MediaQueryData.textScaleFactor`, and that makes it difficult to remove `MediaQueryData.textScaleFactor` in the future.
## A full list of affected APIs in this PR
Deprecated: The method/getter/setter/argument is annotated with a `@Deprecated()` annotation in this PR, and the caller should replace it with `textScaler` instead. Unless otherwise specified there will be a Flutter fix available to help with migration but it's still recommended to migrate case-by-case.
**Replaced**: The method this `textScaleFactor` argument belongs to is rarely called directly by user code and is not overridden by any of the registered custom tests, so the argument is directly replaced by `TextScaler`.
**To Be Deprecated**: The method/getter/setter/argument can't be deprecated in this PR because a registered customer test depends on it and a Flutter fix isn't available (or the test was run without applying flutter fixes first). This method/getter/setter/argument will be deprecated in a followup PR once the registered test is migrated.

A lot of material widgets (`Slider`, `RangeSlider`, `TimePicker`, and different types of buttons) also change their layout based on `textScaleFactor`. These need to be handled in a case-by-case fashion and will be migrated in follow-up PRs.
* Add MenuMenuAcceleratorLabel to support accelerators.
* Review Changes
* Review Changed
* Fix default label builder to use characters
* Remove golden test that shouldn't have been there.
This implements a MenuBar widget that can render a Material menu bar, and a MenuAnchor widget used to create a cascading menu in a region. The menus are drawn in the overlay, while the menu bar itself is in the regular widget tree. Keyboard traversal works between the two.
This implementation of the MenuBar uses MenuAnchor to create a cascading menu that contains widgets representing the menu items. These menu items can be any kind of widget, but are typically SubmenuButtons that host submenus, or MenuItemButtons that have shortcut hints (but don't actually activate the shortcuts) and don't host submenus.
Cascading menus can be created outside of a MenuBar by using a MenuAnchor. They can be either given a specific location to appear (a coordinate), or they can be located by the MenuAnchor region that wraps the control that opens them.
The developer may also create a MenuController to pass to the various menu primitives (MenuBar or MenuAnchor) to associate menus so that they can be traversed together and closed together. Creating a controller is not required.
* Update parameters to the `styleFrom` button methods.
* Updated the Flutter fix data to point to this PR.
* Updated handling of background color to better maintain backwards compatibility with previous API.
