Fix no op host debug builds doing work (#178077)
Fixes https://github.com/flutter/flutter/issues/176667

I don't really know what I'm doing here, but as far as I can tell from:

https://github.com/swiftlang/swift/blob/main/docs/Driver.md#output-file-maps
the swift dependencies file is only output for incremental builds, not
builds with whole module optimization enabled.

> "swift-dependencies" entries are required to perform incremental
builds (see below).

This would align with the logs from that issue saying the file is
missing every time (because it is never output in the first place). So
try simply removing it? Fixes the issue for me locally

[Android] Encode the original pointer count in messages that represent Android touch events (#178015)
Android touch events include updates to multiple pointers, but each
pointer data message sent from the embedder to the framework represents
a single pointer. So the Android embedder will send multiple messages
for each touch event, and the framework's AndroidViewController will
reassemble the messages and forward the resulting event to the platform
view.

The AndroidViewController tracks the number of active pointers in its
own local state. If that state is out of sync with the event handled by
the Android embedder, then the AndroidViewController may send duplicate
events to the platform view.

This PR encodes the Android touch event's pointer count in the messages
sent to the framework. This allows the AndroidViewController to reliably
determine whether it has received all of the pointer messages that
originated from an event.

Reland "Update all uses of mutable SkPath methods to use SkPathBuilder" (#178142)
This is a reland of https://github.com/flutter/flutter/pull/177738 with
a fix to the `Op` function in `tools/path_ops`.

To match the previous behavior, `Op` will use `SkPathBuilder::operator=`
to copy the result path so that attributes like the fill type will be
copied.

Use aria-hidden attribute for platform view accessibility on web (#177969)
Use aria-hidden attribute for platform view accessibility on web

Before change:
https://map-1023-before.web.app/

After change:
https://map-1023-after.web.app/

Fixes #171948.

Note: When a descendant element receives focus (for example, a marker),
the browser automatically overrides aria-hidden. This behavior is
correct and expected for accessibility compliance.

This change reverts the following previous change:
This PR introduces a significant refactoring of the web engine's
rendering layer by unifying the `Surface` and `Rasterizer`
implementations. These components have been moved from being
renderer-specific to a generic `compositing` directory, making the
architecture more modular and easier to maintain. The rasterizers are
now renderer-agnostic and are provided with renderer-specific surface
factories via dependency injection. A new `CanvasProvider` abstraction
has also been introduced to manage the lifecycle of the underlying
canvas elements.

A key outcome of this work is that the Skwasm backend now correctly
handles WebGL context loss events. This was achieved by refactoring
`SkwasmSurface` to allow the Dart side to manage the `OffscreenCanvas`
lifecycle. A communication channel between the main thread and the web
worker is now used to gracefully handle context loss and recovery. This
effort also included fixing several related bugs around surface sizing,
resource cleanup, and callback handling in multi-surface scenarios.

To validate these changes, new testing APIs have been added to allow for
the creation of renderer-agnostic surface tests. A new test file,
`surface_context_lost_test.dart`, has been added to verify the context
loss and recovery behavior across all supported renderers, ensuring the
new architecture is robust and reliable.

[web] Unify Surface code between Skwasm and CanvasKit (#177138)
This PR introduces a significant refactoring of the web engine's
rendering layer by unifying the `Surface` and `Rasterizer`
implementations. These components have been moved from being
renderer-specific to a generic `compositing` directory, making the
architecture more modular and easier to maintain. The rasterizers are
now renderer-agnostic and are provided with renderer-specific surface
factories via dependency injection. A new `CanvasProvider` abstraction
has also been introduced to manage the lifecycle of the underlying
canvas elements.

A key outcome of this work is that the Skwasm backend now correctly
handles WebGL context loss events. This was achieved by refactoring
`SkwasmSurface` to allow the Dart side to manage the `OffscreenCanvas`
lifecycle. A communication channel between the main thread and the web
worker is now used to gracefully handle context loss and recovery. This
effort also included fixing several related bugs around surface sizing,
resource cleanup, and callback handling in multi-surface scenarios.

To validate these changes, new testing APIs have been added to allow for
the creation of renderer-agnostic surface tests. A new test file,
`surface_context_lost_test.dart`, has been added to verify the context
loss and recovery behavior across all supported renderers, ensuring the
new architecture is robust and reliable.

[web] Don't add webparagraph suite to CI (#177681)
Fix `generate-builder-json` to only include test bundles that are needed
by enabled test suites.

## Before this PR
The script was unconditionally including all test bundles in CI. The
result is that the `dart2js-canvaskit-experimental-webparagraph` bundle
was being generated, even though it was only required by the
`chrome-dart2js-experimental-webparagraph-ui` suite, which had
`enable-ci: false`.

## After this PR
The script starts by finding all test suites with `enable-ci: true`,
then only adds the bundles required by those suites.

Replace rendering for solid color circles (both filled and stroked) to use SDFs (#177482)
Replace rendering for solid color circles (both filled and stroked) to
use SDFs. This change improves the visual quality of circle borders,
especially on platforms without MSAA support.

- Adds a vertex and fragment shader that support SDF rendering for both
filled and stroked circles.
- Adds a `Contents` subclass, `CircleContents` that uses these shaders
for rendering
- Modifies `Canvas::DrawCircle` to use this new contents for drawing
circles
- Only supports circles with a solid color paint. Everything else
continues to use the existing behavior
- Adds a playground test that interactively scales circles to ensure
fidelity at all scales.


- Partially fixes https://github.com/flutter/flutter/issues/167181

Add blockAccessibilityFocus flag (#175551)
Add a new flag for a11y focusable

- Accessibility focus, which is the focus used by screen readers like
TalkBack and VoiceOver, is different from input focus.
- Our current logic use some existing flags to decide if a node is
accessibilty focusable. like "if it's a slider / has a check state / has
keyboard focus/..., then it's a11y focusable"
ecbb115ae3/engine/src/flutter/shell/platform/android/io/flutter/view/AccessibilityBridge.java (L98)
- but we lack the ability to explicitly set a node to be unfocusable in
a11y!
- This flag can be used to explicitly set some semantics nodes to be
unfocusable in a11y mode. if it is false, we fall back to the logic "if
it's a slider / has a check state / has keyboard focus/..., then it's
a11y focusable"

future use case 1:
user can set live region to be not focusable, so when content changes,
it will still announce, but the content can't be focused by swiping.
future use case 2:
when pushing a new route like a dialog, setting the semantics nodes in
old pages to be un focusable.

fix(impeller): fix params to glDiscardFrameBufferEXT (#175589)
<!--

Fix parameters to
[glDiscardFramebufferEXT](https://registry.khronos.org/OpenGL/extensions/EXT/EXT_discard_framebuffer.txt)
when an application-defined framebuffer is bound. The `is_default_fbo`
parameter is set to `true` if `color_gles.IsWrapped()` is true, however
according to the GLES spec, a non-default framebuffer is bound if
`glBindFramebuffer(GL_FRAMEBUFFER, framebuffer)` is called with
`framebuffer != 0`:

> _The namespace for framebuffer objects is the unsigned integers, with
zero re-
served by OpenGL ES to refer to the default framebuffer. A framebuffer
object
is created by binding an unused name to the target FRAMEBUFFER._ 

To reproduce this issue, run a flutter application with
`--enable-impeller` on a platform where `glDiscardFramebufferEXT` is
available. The following error is reported:

```
[FATAL:flutter/impeller/renderer/backend/gles/proc_table_gles.h(43)] Fatal GL Error GL_INVALID_ENUM(1280) encountered on call to glDiscardFramebufferEXT
```

*List which issues are fixed by this PR. You must list at least one
issue. An issue is not required if the PR fixes something trivial like a
typo.*

closes #175588

[engine,build] Fix Fuchsia RBE build (#177865)
As in the Dart build here:


fc8b3d7927/build/toolchain/fuchsia/fuchsia_toolchain.gni (L24)

For unknown reasons, the `__config_site` file has to be explicitly
listed as an input to the build to ensure it is available in the RBE
workers.

This PR also cleans up unnecessary flags from the Fuchsia toolchain
definition. The target triple and sysroot flags are already injected
into the compiler flags by the Fuchsia build configs.

Fixes RuntimeEffect when used with ImageFilter.compose and gaussian blur (#177687)
fixes https://github.com/flutter/flutter/issues/170820
fixes https://github.com/flutter/flutter/issues/177611

This PR snapshots the input of a runtimeeffect if its transform is not
identity. This fixes the cases where we use compose with the runtime
effect and the inner effect evaluates to a snapshot that doesn't match
the size of x, such as`runtime_effect(blur(x))`. Blur will perform at
lower resolutions when the sigma is high as an optimization. Blur also
adds a halo around what it is blurring. Previously we could optimize
away this extra render pass when we assumed that the coverage of
inner(x) was the same as x (but potentially just translated), but we
can't do that in practice because of things like gaussian blur.

In order to make this PR work we had to come up with a way to disable
the extra padding that is added to every `RenderToSnapshot`. This is
because users want to to reference specific fragments. The extra border
of padding would increase the texture size of inner(x) and x which
created a jump in the locations calcuated in the fragment shaders when
the inner snapshot's transform would jump from identity to non-identity.
The only other alternative would be to pass in the offset to the
fragment shader but that would be a breaking change.

In order to get the shaders rendering in the right orientation on
opengles I had to switch the shaders to do a `uv.y = 1.0 - uv.y`. This
is in the documentation for ImageFilter.shader but it is an annoying
gotcha. Hopefully this doesn't break someone if the logic was different
previously for ImageFilter.compose but this is the correct thing to do
and since it wasn't tested, there is no breaking change.

Fixes SettingsChannelTest flake (#177061)
Fixes `SettingsChannelTest` failure that occurs when other Android
embedding tests touch the singleton queue that the `SettingsChannel`
manages.

Instead of the test making assertions based on the theoretical
generation number of `SentConfiguration`s added to the queue, the
assertions are isntead made relative to the exaction generation number
of those `SentConfiguration`s.

Fixes https://github.com/flutter/flutter/issues/176413. I tested this
fix in https://github.com/flutter/flutter/pull/175937; an example
passing build:
https://ci.chromium.org/ui/p/flutter/builders/try/Linux%20Engine%20Drone/3641486/overview.

Copy symlinks when creating android cipd package, and update to package w/ symlinks (#177638)
`cp -r` isn't [well
defined](https://unix.stackexchange.com/questions/18712/difference-between-cp-r-and-cp-r-copy-command),
but on my mac (and probably on the other android team members macs) it
doesn't copy symlinks (instead it follows the symlink and copies the
file).

`cp -a` is well defined, and copies the symlinks. This will probably fix
https://github.com/flutter/flutter/issues/177286, the symlinks are there
for sure locally so it is just a question of if the upload process
tramples them. But it sounds like cipd supports this, so I imagine it
will fix the issue.

Refactor OverlayPortal semantics (#173005)
Fixes https://github.com/flutter/flutter/issues/163576
Fixes https://github.com/flutter/flutter/issues/175184

This PR refactored the grafting part on `OverlayPortal`. Originally, the
semantics tree of `OverlayPortal` was constructed/grafted in render
object phase to make sure the correctness of the traversal order.
However this resulted wrong hit-test order and the issue surfaced on
web. With the fact that on web we are not able to graft/correct hit-test
order tree, this PR:
* Reverts the original grafting of the `OverlayPortal` so the hit-test
order is always correct.
* Then, we adds the grafting and updates the traversal order when we
send `childrenInTraversalOrder` to engine.
* Updating `childrenInTraversalOrder` causes it have different length
from the length of `childrenInHitTestOrder` and wrong hit-test transform
of the `OverlayPortal` children because when the transform is
calculated, it assumes a correct traversal order. To fix these issues,
this PR also:
  * recalculates the transform for `OverlayPortal` children.
  * adds `hitTestTransform` property and pass it to Android engine.
* skip grafting for web because it assumes the same length of
`childrenInTraversalOrder` and `childrenInHitTestOrder`.
* added grafting by using `ARIA-owns` in web engine to fix the traversal
order.

Adds a `gn` flag to optimize builds for size over speed when
optimization is requested. The existing behaviour is that Windows,
Android and iOS builds are always optimized for size. This has not
changed.

The flag allows other builds to prefer size over speed.
