* Add test case for Flutter Issue #27677 as a benchmark.
See https://github.com/flutter/flutter/issues/27677
I got the following results running the test on a Moto E2 which
will help us determine how much we can gain by analyzing the
operations and eliminating unnecessary repaints based on
dirty rectangles/regions.
no blurs - avg 216.0 fps over 3 samples
blur the group - avg 22.9 fps over 3 samples
blur each txt - avg 3.4 fps over 3 samples
* Added the new benchmark to be tracked on the dashboard.
Updates the Podfile template to use the CocoaPod disable_input_output_paths installation option which prevents the [CP] Embed Pods Frameworks build phase from outputting the Flutter.framework files.
* Gradle generates ELF shared libraries instead of AOT snapshots.
* `flutter build apk/appbundle` supports multiple `--target-platform` and defaults to `android-arm` and `android-arm64`.
* `flutter build apk` now has a flag called `--split-per-abi`.

This adds support for game controller buttons. It adds some supplemental USB HID codes that aren't available from the Chromium source code, and maps those on Android to the game pad buttons that Android supports. Other platforms are not supported yet.

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.

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.
https://github.com/flutter/flutter/issues/32374
* Deprecates `BinaryMessages` in favor of a default instance of `BinaryMessenger`, called `defaultBinaryMessenger`
* Platform channels use the `defaultBinaryMessenger` for their binaryMessenger default argument.
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.
This adds a maintenance script that will allow us to "unpublish" a release: basically remove it from the cloud storage so that we're no longer serving it from the website.
Obviously, gsutil access to the cloud storage server is required for this to function.
* Clean up some flutter_tools tests
* Remove arbitrary retry that happens even for fundamental errors, and generally clean up _DevFSHttpWriter.
* Update dependencies (requires fixes; see next commit)
* Fixes for new dependencies.
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.

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.
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 is a re-land of #31561, after fixing performance regressions.
Added change listening to the MouseTracker so that the Listener and tooltip can react to whether or not a mouse is connected at all. Added a change check to make sure Listener only repaints when something changed.
Fixes#22817
Fixes a typo in the key generator readme.
Updated the examples in the readme to reflect that the examples were for physical key codes, where we're actually talking about logical key codes there.
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.

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.

* Added support for authentication codes for the VM service.
Previously, a valid web socket connection would use the following URI:
`ws://127.0.0.1/ws`
Now, by default, the VM service requires a connection to be made with a
URI similar to the following:
`ws://127.0.0.1:8181/Ug_U0QVsqFs=/ws`
where `Ug_U0QVsqFs` is an authentication code generated and shared by
the
service.
This behavior can be disabled with the `--disable-service-auth-codes`
flag.
Previously, I used the Android emulator for testing and everything
seemed to work fine with stdout (if I remember correctly). But our
devicelab uses real Android devices and the warnings are routed to
stderr. Hence change stdout to stderr in the test.
## Description
Print actionable warnings if `flutter drive` (where most of our performance benchmarks come from) is run in debug mode and it tries to gather benchmarks using `traceAction`.

## Tests
I added the following tests:
* drive_perf_debug_warning devicelab test
updates the regex the analyzer uses, so it should be able to recognize expressions such as
const Foo a = Foo(); as "other code" rather than a constructor call.
When we package Flutter, we used to find the "current" tag (which is the version number) by starting at the revision we are building on and looking backwards in time to find the most recent tag. This causes problems on release builds when we failed to tag properly.
This PR makes the packaging script be more strict by requiring the given revision to itself have a tag, but only when we're publishing the result. When we're not publishing the result, it's more lenient, since otherwise we couldn't test packaging on non-release commits.
I also renamed ProcessRunnerException to PreparePackageException, since we were using that exception more generally than just for processes.

## Description
This moves another 15-20ms from the animation jank of one of our important client to the startup latency. Unfortunately, this is probably not captured in our current benchmarks (presumably some other bottlenecks overshadow this shader compilation in the worst_frame benchmark). Considering that drawing images is such a common operation, maybe we should add one in the future to benchmark this.
We need this PR to land soon for our client because this changes the API to return Future.

Adds SHA256 checksums to the released package database, in preparation for showing them on the download website. (I'll update the existing data by hand).
Fixes#28465
This patch adds a default shader warm up process which moves shader compilation from the animation time to the startup time. This also provides an extension for `runApp` so developers can customize the warm up process.
This should reduce our worst_frame_rasterizer_time_millis from ~100ms to ~20-30ms for both flutter_gallery and complex_layout benchmarks. Besides, this should also have a significant improvement on 90th and 99th percentile time (50%-100% speedup in some cases, but I haven't tested them thoroughly; I'll let our device lab collect the data afterwards).
The tradeoff the is the startup time (time to first frame). Our `flutter run --profile --trace-startup` seems to be a little noisy and I see about 100ms-200ms increase in that measurement for complex_layout and flutter_gallery. Note that this only happens on the first run after install or data wipe. Later the Skia persistent cache will remove the overhead.
This also adds a cubic_bezier benchmark to test the custom shader warm up process.
This should fix https://github.com/flutter/flutter/issues/813 (either by `defaultShaderWarmUp`, or a `customShaderWarmUp`).
