* Make FlAccessibleNode derivable
This allows introducing specialized subclasses that implement such a11y
interfaces as AtkEditableText that should not be implemented for the
generic node.
* FlAccessibleNode: add set value, text selection & perform action
Prepare API required for the upcoming AtkEditableText implementation.
* FlViewAccessible: postpone child node creation
This changes the a11y node creation flow so that (unknown) child nodes
are not pre-created when their parent is updated but "pending" child
node IDs are collected for later. Parent-child relationships are
established at the end of update batches when all nodes have been
created.
* Add FlAccessibleTextField that implements AtkEditableText
Solves: flutter/flutter#103191
* FlEngine: add fl_engine_update_accessibility_features()
* FlSettings: add API for high-contrast & animations
* FlEngine: allow passing mock messenger at construction time
* FlSettingsPlugin: report accessibility features
* Implement toGpuImage, a synchronous, GPU-resident version of
Picture.toImage.
This method kicks off asynchronous work on the raster task runner.
If it fails to rasterize, it will synchronously throw later when
the user attempts to draw to a canvas.
This supports several use cases:
- Quickly snapping off an expensive-to-rasterize image for reuse
across multiple frames.
- Applying multi-pass filters to a render target.
This patch amends flutter_tester so that it can produce an image
object, but that image will always be a grey and white four square checkerboard.
Adds support for CanvasKit on Web, which basically already used
this method for its Picture.toImage implementation.
Throws an UnsupportedError for HTML on Web, since any implementation
there would almost certainly be slower than drawPicture.
Roll Swiftshader, ANGLE, and Vulkan deps.
Updates license bot for new locations of licenses and new files
in roll.
Converts unit test harnesses to use SwANGLE, which is the
supported way of using SwiftShader as a software backend for GLES.
Updates goldens due to swiftshader changes.
Fixes up include paths to avoid directly including third_party
code by that name, which is unlikely to work in other build
environments.
Includes upstream patches to ANGLE and SwiftShader to build in our
windows environments, as well as patches to Skia to support
defining the location of VulkanMemoryAllocator and a patch to ANGLE
to support opting into a newer version of VMA.
Merges most (but not all) of the impeller .clang-tidy rules into the
main .clang-tidy config. Merges:
readability-identifier-naming.PrivateMemberSuffix (_)
readability-identifier-naming.EnumConstantPrefix (k)
modernize-use-default-member-init.UseAssignment
Does not merge:
readability-identifier-naming.PublicMethodCase (CamelCase)
readability-identifier-naming.PrivateMethodCase (CamelCase)
These last two are not merged due to the non-trivial number of existing
field accessors that use field_name() methods to directly return
field_name_. While these are permitted by the C++ style guide, we may
want to move to a single, simple rule and name everything in CamelCase.
These can be enabled in a followup patch.
No new tests added, since this change is style-only.
Let MockBinaryMessenger internally manage the FlBinaryMessenger wrapper
instance and provide it via operator FlBinaryMessenger*() to avoid
having to create two objects in every test. The same technique was used
for MockSettings in #32618.
Towards implementing the FragmentProgram API in Impeller.
Specifies an Impeller specific format for data the renderer can use to create
pipelines with user supplied shader stages at runtime.
The data is in the form of a flatbuffer with a known schema.
This patch implements the wire format, creating and loading the program
payloads, and creating pipeline state objects using these payloads.
If the user supplied SPIRV intended for the older API, the loader will reject
this invalid payload. This is probably not going to be too much of an issue
because the FragmentProgram API will probably be modified to only allow buffers
loaded from asset managers. But still, in the meantime, I am using the old API
to pass these new buffers.

This PR is a continuation of #33111 and includes necessary changes to test the `TextInputType.setClient()` platform channel call. Testing the actual text input flow requires a mock IM context that will follow in a separate PR.
* [Linux] pass GdkWindow instead of FlView to FlTextInputPlugin
* [Linux] add MockBinaryMessenger::ReceiveMessage()
* [Linux] add test for TextInputType.setClient
* Drop the offscreen window
GdkOffscreenWindow requires display & screen which is a problem in
headless mode. Luckily, we don't really need a window instance in tests
because its only passed as a client window to the IM context which will
be mocked out when we get to tests that depend on it.
