This adds a ShortcutsRegistry for ShortcutActivator to Intent mappings that can be modified from its descendants.
This is so that descendants can make shortcuts dynamically available to a larger portion of the app than just their descendants. This is a precursor needed by the new MenuBar, for instance, so that the menu bar itself can be placed where it likes, but the shortcuts it defines can be in effect for most, if not all, of the UI surface in the app. For example, the "Ctrl-Q" quit binding would need to work even if the focused widget wasn't a child of the MenuBar.
This just provides the shortcut to intent mapping, the actions activated by the intent are described in the context where they make sense. For example, defining a "Ctrl-C" shortcut mapped to a "CopyIntent" should perform different functions if it happens while a TextField has focus vs when a drawing has focus, so those different areas would need to define different actions mapped to "CopyIntent". A hypothetical "QuitIntent" would probably be active for the entire app, so would be mapped in an Actions widget near the top of the hierarchy.
This adds a simple VoidCallbackAction and VoidCallbackIntent that allows configuring an intent that will invoke a void callback when the intent is sent to the action subsystem. This allows binding a shortcut directly to a void callback in a Shortcuts widget.
I also added an instance of VoidCallbackAction to the default actions so that simply binding a shortcut to a VoidCallbackIntent works anywhere in the app, and you don't need to add a VoidCallbackAction at the top of your app to make it work.
Roll dependendencies
This rolls depdendencies to latest using
flutter update-packages --force-upgrade
This change includes three code changes:
* Removes charcode from the dependencies allowlist since it no longer
appears in the transitive closure of dependencies of the flutter,
flutter_test, flutter_driver, flutter_localizations, and
integration_test packages.
* Uses Resolver.create instead of the deprecated Resolver constructor.
The default Resolver constructor has been deprecated in favour of the
static Resolver.create() factory function, which unfortunately happens
to be async. Propagated the async-ness up the chain.
This change was partially reverted and the deprecation ignored in this
patch until package:coverage can be rolled internally at Google.
* Eliminates the use of the deprecated packagesPath parameter to
HitMap.parseJson. This parameter was deprecated and replaced with
packagePath in https://github.com/dart-lang/coverage/pull/370 which
was part of the overall deprecation of the .packages file in Dart
itself https://github.com/dart-lang/sdk/issues/48272. The overall goal
being that end-user code shouldn't need to know about implementation
details such as whether dependency information is stored in a
.packages file or a package_info.json file, but rather use the
package_config package to obtain the package metadata and perform
other functions such as resolving its dependencies to filesystem
paths. packagesPath was replaced by packagePath, which takes the path
to the package directory itself. Internally, package:coverage then
uses package_config to do the rest of the package/script URI
resolution to filesystem paths.
This change was partially reverted and the deprecation ignored in this
patch until package:coverage can be rolled internally at Google.
This is a pre-update prior to updating flutter_template_images in
https://github.com/flutter/flutter/pull/103739

When re-applying the partially-reverted changes to code coverage,
we'll need to patch host_entrypoint.dart internally to await the Future
that we'll be returning rather than a non-async value.
When I added localizations for shortcut keys, I added some that actually can't be shortcut keys, so I'm removing them again. These are mostly Japanese-specific keys that don't even appear on modern keyboards for the most part.
Also, added menuBarMenuLabel for an accessibility label for menu bar menus.
I modified the code for the localization generation scripts to add a --remove-undefined flag that will remove any localizations that don't appear in the canonical locale.
