The previous attempt to do this by setting the theme to
Theme_Translucent_NoTitleBar was reported to offsetting touch events on
specific Xiaomi devices.

By default alpha is not preserved for the VD's contents.
We make the window translucent as a side effect of doing so is preserving alpha.
There should not be extra performance cost for setting the window to be translucent as there is only a single window within the VD.

Fixes flutter/flutter#33756

libapp.so contains compiled application Dart code.  On most Android systems,
this library can be loaded by calling dlopen("libapp.so"), which will search
Android's default library directories.

On some Android devices this does not work as expected.  As a workaround, this
patch provides a fallback path to libapp.so based on ApplicationInfo.nativeLibraryDir.

Fixes https://github.com/flutter/flutter/issues/35838

Un-deprecated FlutterViewController's binaryMessenger.  Leaving it as
a valid convenience method and to help minimize a breaking change.

With this, plugins can know whether or not their input connection should
be cached. In very rare cases this can be used by plugins to know how to
more properly handle their own input connections, in cases where they're
overriding typical input behavior themselves.

Updates the way FLEViewController and FLEEngine interact,
making their APIs much more closely aligned with the iOS versions
of the classes.

As part of the change, removes the need for an explicit launch
call on FLEViewController. Also adds entrypoint support when
running an engine directly, matching iOS.

Breaking change for macOS runners.

Part of https://github.com/flutter/flutter/issues/31735

Rather than clients needing to create an appropriate view in a XIB and
attach it to an FLEViewController, which is error-prone, have
FLEViewController create its own view programatically. The view is now
an internal detail, so calling setView: on an FLEViewController will no
longer work.

As a result of the view being internal, the public API surface is
simplified.

This is a breaking change for macOS Runners.

Got rid of the black frame by synchronizing the main thread with the
gpu thread to make sure a frame is rendered before presenting the
view.

This patch reworks image decompression and collection in the following ways
because of misbehavior in the described edge cases.

The current flow for realizing a texture on the GPU from a blob of compressed
bytes is to first pass it to the IO thread for image decompression and then
upload to the GPU. The handle to the texture on the GPU is then passed back to
the UI thread so that it can be included in subsequent layer trees for
rendering. The GPU contexts on the Render & IO threads are in the same
sharegroup so the texture ends up being visible to the Render Thread context
during rendering. This works fine and does not block the UI thread. All
references to the image are owned on UI thread by Dart objects. When the final
reference to the image is dropped, the texture cannot be collected on the UI
thread (because it has not GPU context). Instead, it must be passed to either
the GPU or IO threads. The GPU thread is usually in the middle of a frame
workload so we redirect the same to the IO thread for eventual collection. While
texture collections are usually (comparatively) fast, texture decompression and
upload are slow (order of magnitude of frame intervals).

For application that end up creating (by not necessarily using) numerous large
textures in straight-line execution, it could be the case that texture
collection tasks are pending on the IO task runner after all the image
decompressions (and upload) are done. Put simply, the collection of the first
image could be waiting for the decompression and upload of the last image in the
queue.

This is exacerbated by two other hacks added to workaround unrelated issues.
* First, creating a codec with a single image frame immediately kicks of
  decompression and upload of that frame image (even if the frame was never
  request from the codec). This hack was added because we wanted to get rid of
  the compressed image allocation ASAP. The expectation was codecs would only be
  created with the sole purpose of getting the decompressed image bytes.
  However, for applications that only create codecs to get image sizes (but
  never actually decompress the same), we would end up replacing the compressed
  image allocation with a larger allocation (device resident no less) for no
  obvious use. This issue is particularly insidious when you consider that the
  codec is usually asked for the native image size first before the frame is
  requested at a smaller size (usually using a new codec with same data but new
  targetsize). This would cause the creation of a whole extra texture (at 1:1)
  when the caller was trying to “optimize” for memory use by requesting a
  texture of a smaller size.
* Second, all image collections we delayed in by the unref queue by 250ms
  because of observations that the calling thread (the UI thread) was being
  descheduled unnecessarily when a task with a timeout of zero was posted from
  the same (recall that a task has to be posted to the IO thread for the
  collection of that texture). 250ms is multiple frame intervals worth of
  potentially unnecessary textures.

The net result of these issues is that we may end up creating textures when all
that the application needs is to ask it’s codec for details about the same (but
not necessarily access its bytes). Texture collection could also be delayed
behind other jobs to decompress the textures on the IO thread. Also, all texture
collections are delayed for an arbitrary amount of time.

These issues cause applications to be susceptible to OOM situations. These
situations manifest in various ways. Host memory exhaustion causes the usual OOM
issues. Device memory exhaustion seems to manifest in different ways on iOS and
Android. On Android, allocation of a new texture seems to be causing an
assertion (in the driver). On iOS, the call hangs (presumably waiting for
another thread to release textures which we won’t do because those tasks are
blocked behind the current task completing).

To address peak memory usage, the following changes have been made:
* Image decompression and upload/collection no longer happen on the same thread.
  All image decompression will now be handled on a workqueue. The number of
  worker threads in this workqueue is equal to the number of processors on the
  device. These threads have a lower priority that either the UI or Render
  threads. These workers are shared between all Flutter applications in the
  process.
* Both the images and their codec now report the correct allocation size to Dart
  for GC purposes. The Dart VM uses this to pick objects for collection. Earlier
  the image allocation was assumed to 32bpp with no mipmapping overhead
  reported. Now, the correct image size is reported and the mipmapping overhead
  is accounted for. Image codec sizes were not reported to the VM earlier and
  now are. Expect “External” VM allocations to be higher than previously
  reported and the numbers in Observatory to line up more closely with actual
  memory usage (device and host).
* Decoding images to a specific size used to decode to 1:1 before performing a
  resize to the correct dimensions before texture upload. This has now been
  reworked so that images are first decompressed to a smaller size supported
  natively by the codec before final resizing to the requested target size. The
  intermediate copy is now smaller and more promptly collected. Resizing also
  happens on the workqueue worker.
* The drain interval of the unref queue is now sub-frame-interval. I am hesitant
  to remove the delay entirely because I have not been able to instrument the
  performance overhead of the same. That is next on my list. But now, multiple
  frame intervals worth of textures no longer stick around.

The following issues have been addressed:
* https://github.com/flutter/flutter/issues/34070 Since this was the first usage
  of the concurrent message loops, the number of idle wakes were determined to
  be too high and this component has been rewritten to be simpler and not use
  the existing task runner and MessageLoopImpl interface.
* Image decoding had no tests. The new `ui_unittests` harness has been added
  that sets up a GPU test harness on the host using SwiftShader. Tests have been
  added for image decompression, upload and resizing.
* The device memory exhaustion in this benchmark has been addressed. That
  benchmark is still not viable for inclusion in any harness however because it
  creates 9 million codecs in straight-line execution. Because these codecs are
  destroyed in the microtask callbacks, these are referenced till those
  callbacks are executed. So now, instead of device memory exhaustion, this will
  lead to (slower) exhaustion of host memory. This is expected and working as
  intended.

This patch only addresses peak memory use and makes collection of unused images
and textures more prompt. It does NOT address memory use by images referenced
strongly by the application or framework.

Adds an initial version of FLEDartProject, which contains the

FlutterDartProject, and likely share a significant portion of the
implementation.

This is a breaking change for macOS runners.

This is part of a bigger change that will facilitate us
to act on this `RasterStatus`. The specific case is where
after pre-roll we might decide to want to merge the threads
and re-submit the frame -- `RasterStatus::kResubmit` can then
let us achieve this result.

change.

Further changes will move channels from FLEViewController to FLEEngine,
and further align the APIs and functionality with the iOS version.

Part of #32421

Rename methods in the MutatorsStack to Pascal case to match standard cpp style
Refactor the operator== for Mutator class

* ExternalViewEmbedder can CancelFrame after pre-roll

  nested transactions.

* Update flow/embedded_views.h

* refactoring to move the mutator stack handling to preroll

* more review fixes

* Add support for external view embedded to know if it has changed

* remove the need to reset

* address comments

* Rename to HasPendingViewOperations

* refactoring to move the mutator stack handling to preroll

* more review fixes

Android Embedding Refactor PR31: Integrate platform views with the new embedding and the plugin shim. (#9206)

This is a reland of #9364 with fixes for Fuchsia.

000cf0560c clean up type_literal_test

b71d2d9996 [llvm] Add initial scaffolding
5f2bcd9d6c [vm/bytecode] Reuse flow graph building for recognized methods

This includes a breaking change: https://dart-review.googlesource.com/c/sdk/+/105241
```
  Dart_CreateIsolate -> Dart_CreateIsolateGroup
  Dart_IsolateCreateCallback -> Dart_IsolateGroupCreateCallback
  Dart_IsolateCleanupCallback -> Dart_IsolateGroupShutdownCallback
  Dart_CreateIsolateFromKernel -> Dart_CreateIsolateGroupFromKernel
  Dart_CurrentIsolateData -> Dart_CurrentIsolateGroupData
  Dart_IsolateData -> Dart_IsolateGroupData

  Dart_InitializeParams.create -> Dart_InitializeParams.create_group
  Dart_InitializeParams.cleanup -> Dart_InitializeParams.shutdown_group
  Dart_InitializeParams.shutdown -> Dart_InitializeParams.shutdown_isolate
```

This broke the Fuchsia build.

This reverts commit 45e1ad27.

These services will replace fuchsia.net.SocketProvider.

Note that dart_{aot,jit}_product_runner.cmx were invalid before this
change. I'm not sure how that was allowed to happen.

... replaced by fuchsia.tracing.provider.Registry.
