When attempting to release the Flutter 3.24.1 hotfix, Flutter framework post submits failed due to the following error:

```

```

I've updated the tests to include the listed artifact.  

### Open questions
1. Is it possible that the test failed only on the first binary?
2. Do we expect a need to add the remainder of the [entitlement changes](flutter-team-archive/engine@c9b9d57)?
3. I am under the assumption that the bots pull from master and are not branch specific, is this a correct assumption?

### Problem

Enabling the Swift Package Manager feature caused post-submit tests to fail on Mac x64 hosts:

<details>
<summary>Example error...</summary>

</details>

### Reproduction

On a mac x64 host:

1. Switch to the latest master channel: `flutter channel master ; flutter upgrade`
1. Disable the Swift Package Manager feature: `flutter config --no-enable-swift-package-manager`
2. Create a Flutter project
2. [Edit the Xcode project manually to add the prepare pre-action](https://docs.flutter.dev/packages-and-plugins/swift-package-manager/for-app-developers#step-2-add-run-prepare-flutter-framework-script-pre-action)
3. Run `flutter run` (`flutter build ios` does not reproduce this issue).

### Background

Previously, the Flutter framework was unpacked in the Xcode target's build. Unfortunately, this happens after Swift packages are built; this prevented Swift packages from using the Flutter framework.

To fix this, we added an Xcode pre-action that unpacks the Flutter framework _before_ Swift Package Manager builds packages. The Xcode target still runs the Flutter framework unpack step, but this step no-ops if the unpack step has the exact same inputs. 

```mermaid
flowchart LR
  A[flutter run -d iphone] --> B(Build Xcode project)
  B --> C(Xcode 'prepare framework' pre-action)
  B --> G[Build Swift packages]
  B --> D(Build 'Runner' target)
  C --> E[Unpack Flutter framework #1]
  D --> F["
  Unpack Flutter framework #2
  (No-ops if inputs are same as #1)
  "]
```

flutter#150052 added an optimization that made it more likely the second unpack step no-ops by fixing a case where the target architecture input could be different:

> When using SwiftPM, we use `flutter assemble` in an Xcode Pre-action to run the `debug_unpack_macos` (or profile/release) target. This target is also later used in a Run Script build phase. Depending on `ARCHS` build setting, the Flutter/FlutterMacOS binary is thinned. In the Run Script build phase, `ARCHS` is filtered to the active arch. However, in the Pre-action it doesn't always filter to the active arch. As a workaround, assume arm64 if the [`NATIVE_ARCH`](https://developer.apple.com/documentation/xcode/build-settings-reference/#NATIVEARCH) is arm, otherwise assume x86_64.

This optimization is only applied if [`ONLY_ACTIVE_ARCH`](https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/XcodeBuildSettingRef/1-Build_Setting_Reference/build_setting_ref.html#//apple_ref/doc/uid/TP40003931-CH3-SW157) is `YES`.

### Problem

`buildXcodeProject` incorrectly always sets `ONLY_ACTIVE_ARCH` to `YES` if the Xcode built is for a single architecture:

https://github.com/flutter/flutter/blob/6abef222514e8039bde5c47ab7864abbc4caf7e8/packages/flutter_tools/lib/src/ios/mac.dart#L353-L361

This is incorrect! If the host architecture is `x64` but the target architecture is `arm64`, [`ONLY_ACTIVE_ARCH`](https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/XcodeBuildSettingRef/1-Build_Setting_Reference/build_setting_ref.html#//apple_ref/doc/uid/TP40003931-CH3-SW157) should be `NO`.

This caused the prepare pre-action to incorrectly use x64 as the target architecture for arm64 devices on an x64 host, which in turn caused builds to fail if Swift Package Manager was enabled.

### Solution

This change updates `buildXcodeProject` to set `ONLY_ACTIVE_ARCH` correctly.

This change also updates the prepare pre-action's to be more conservative in applying the optimization that filters the target architecture. This ensures that the build still works (but without the optimization) if `ONLY_ACTIVE_ARCH` is incorrectly set.

This unblocks: flutter#151567

### DeviceLab test

This problem reproduces if you `flutter run` to an iPhone Arm64 device from an x64 mac host with the Swift Package Manager feature enabled.

I ran an affected DeviceLab test to verify the fix works as expected:

Description | CI test | Result
-- | -- | --
SwiftPM enabled without this fix: flutter#154750 | [Link](https://ci.chromium.org/ui/p/flutter/builders/try.shadow/Mac_ios%20rrect_blur_perf_ios__timeline_summary/7/overview) | � 
SwiftPM enabled with this fix: flutter#154749 | [Link](https://ci.chromium.org/ui/p/flutter/builders/try.shadow/Mac_ios%20rrect_blur_perf_ios__timeline_summary/8/overview) | â�

The crash indicates that FlutterJNI is returning a nullptr
SurfaceControl.Transaction. That likely indicates that we're trying to
rasterize a frame before the platform view controller is setup.
Potentially a startup race?

At any rate, if the PVC is null that means there is no platform views -
so it should be safe to create a tx on the fly. Interestingly I cannot
repro this locally even on the same device.

```

Currently when using a `CustomScrollView`, screen readers cannot list or
move focus to elements that are outside the current Viewport and cache
extent because we do not create semantic nodes for these elements.

This change introduces `SliverEnsureSemantics` which ensures its sliver
child is included in the semantics tree, whether or not it is currently
visible on the screen or within the cache extent. This way screen
readers are aware the elements are there and can navigate to them /
create accessibility traversal menus with this information.
* Under the hood a new flag has been added to `RenderSliver` called
`ensureSemantics`. `RenderViewportBase` uses this in its
`visitChildrenForSemantics` to ensure a sliver is visited when creating
the semantics tree. Previously a sliver was not visited if it was not
visible or within the cache extent. `RenderViewportBase` also uses this
in `describeSemanticsClip` and `describeApproximatePaintClip` to ensure
a sliver child that wants to "ensure semantics" is not clipped out if it
is not currently visible in the viewport or outside the cache extent.
* `RenderSliverMultiBoxAdaptor.semanticBounds` now leverages its first
child as an anchor for assistive technologies to be able to reach it if
the Sliver is a child of `SliverEnsureSemantics`. If not it will still
be dropped from the semantics tree.
* `RenderProxySliver` now considers child overrides of `semanticBounds`.

On the engine side we move from using a joystick method to scroll with
`SemanticsAction.scrollUp` and `SemanticsAction.scrollDown` to using
`SemanticsAction.scrollToOffset` completely letting the browser drive
the scrolling with its current dom scroll position "scrollTop" or
"scrollLeft". This is possible by calculating the total quantity of
content under the scrollable and sizing the scroll element based on
that.

This change reverts the following previous change:
Currently when using a `CustomScrollView`, screen readers cannot list or
move focus to elements that are outside the current Viewport and cache
extent because we do not create semantic nodes for these elements.

This change introduces `SliverEnsureSemantics` which ensures its sliver
child is included in the semantics tree, whether or not it is currently
visible on the screen or within the cache extent. This way screen
readers are aware the elements are there and can navigate to them /
create accessibility traversal menus with this information.
* Under the hood a new flag has been added to `RenderSliver` called
`ensureSemantics`. `RenderViewportBase` uses this in its
`visitChildrenForSemantics` to ensure a sliver is visited when creating
the semantics tree. Previously a sliver was not visited if it was not
visible or within the cache extent. `RenderViewportBase` also uses this
in `describeSemanticsClip` and `describeApproximatePaintClip` to ensure
a sliver child that wants to "ensure semantics" is not clipped out if it
is not currently visible in the viewport or outside the cache extent.
* `RenderSliverMultiBoxAdaptor.semanticBounds` now leverages its first
child as an anchor for assistive technologies to be able to reach it if
the Sliver is a child of `SliverEnsureSemantics`. If not it will still
be dropped from the semantics tree.
* `RenderProxySliver` now considers child overrides of `semanticBounds`.

On the engine side we move from using a joystick method to scroll with
`SemanticsAction.scrollUp` and `SemanticsAction.scrollDown` to using
`SemanticsAction.scrollToOffset` completely letting the browser drive
the scrolling with its current dom scroll position "scrollTop" or
"scrollLeft". This is possible by calculating the total quantity of
content under the scrollable and sizing the scroll element based on
that.

When building
https://github.com/flutter/samples/tree/main/add_to_app/multiple_flutters,
the `[CP-User] Run Flutter Build multiple_flutters_module Script` step
failed with:
```
Showing Recent Messages
[   +3 ms] Improperly formatted define flag: 
[        ] 
           #0      throwToolExit (package:flutter_tools/src/base/common.dart:34:3)
           #1      AssembleCommand._parseDefines (package:flutter_tools/src/commands/assemble.dart:279:9)
```

the command was:
```
 /Users/<User>/flutter/bin/flutter --verbose assemble --no-version-check --output=/Users/<User>/Library/Developer/Xcode/DerivedData/MultipleFluttersIos-<Hash>/Build/Products/Debug-iphonesimulator/ -dTargetPlatform=ios -dTargetFile=lib/main.dart -dBuildMode=debug -dConfiguration=Debug -dIosArchs=arm64 -dSdkRoot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator26.0.sdk -dSplitDebugInfo= -dTreeShakeIcons=false -dTrackWidgetCreation=true -dDartObfuscation=false -dAction=build -dFrontendServerStarterPath= --ExtraGenSnapshotOptions= --DartDefines= --ExtraFrontEndOptions= -dSrcRoot=/Users/<User>/flutter_debug/samples/add_to_app/multiple_flutters/multiple_flutters_ios -dTargetDeviceOSVersion=26.0 -dCodesignIdentity=- debug_ios_bundle_flutter_assets
```

the empty `--DartDefines=` comes from
https://github.com/flutter/flutter/blob/68cddc9bf5c449d5a55fe48ebb9b446ef76ae6b0/packages/flutter_tools/bin/xcode_backend.dart#L660

This PR makes `_parseDefines` ignore these empty dart defines.

Try copying this configuration used by other tests as a speculative fix.
I can't get this test to kick off in presubmit, so I suppose we will
just try this. The test is marked bringup anyways so it won't block the
tree if this doesn't help.

Reason for revert: removal of some snapshot binaries break mac code
signing

Looks like the removal of the MCP server snapshot (and others) caused
the codesigning failure.

Log from the Dart SDK roll that was in the reverted patch:
https://dart.googlesource.com/sdk.git/+log/6833224264116d1becc20dd037d6c25c92194612..3cdc25e8ffe98c61b36af485573639dc833b75cb

Failure logs for arm64 and x64 bots both show the same errors:

/Volumes/Work/s/w/ir/x/w/flutter/bin/cache/dart-sdk/bin/snapshots/kernel-service.dart.snapshot

If this commit is removing binaries from the cache, this test should be fixed by
removing the relevant entry from either the "binariesWithEntitlements" or
"binariesWithoutEntitlements" getters in dev/tools/lib/codesign.dart.

Fixes flutter#184725

This PR makes the tool exit when building with XCode and we didn't parse
any build setting. I understand that there are no cases where this map
can be empty, as it includes the app bundle ID, which is required when
building.

If we don't exit, it can show unrelated error messages to the users
which could be confusing and hard to debug.
For instance, from the linked issue, one could end up getting: `No valid
code signing certificates were found` simply because the development
team build setting was not available, despite having valid certificates
installed.

Sample output:

…on documentation (flutter#190842)

There are 2 files in this pr. One is a document the ai used to keep
track of work. More importantly it acts kind of like issues so it
references the items in future prs. The second is user facing website
documentation. I do not know if we will use it verbatim but for the set
of prs lets treat that md doc as human understandable documentation that
we must understand before landing the next pr.

Reviewers: When the pr is out of draft and your comments are fully
addressed please prioritize this pr over other work. The review bar is
higher, the number of reviews has more people and the work for the next
pr is already done.

Standard review context for this pr stack

This is PR is part of an 11 pr stack to migrate the "newdsl"
`gradle-api` specifically in agp 9.1.0.
The complete stack has pass pre submits, post submits and customer
tests.
https://flutter-dashboard.appspot.com/#/build?repo=flutter&branch=experimental/agp-gradle-api

All of the code was LLM authored. A mix of manual prompting, automatic
prompting, several models and adversarial review. The combined sessions
are enough that I cannot include relevant prompts like I have been doing
on other prs.

If you want to review the pr stack you can find it here. These prs will
be abandoned/closed as prs land into flutter/flutter.

agp-api-doc)
2. reidbaker-agent#2 (branch:
agp-internal-utils)
3. reidbaker-agent#3 (branch:

10. reidbaker-agent#10 (branch:
agp-newdsl-flip)
11. reidbaker-agent#11 (branch:
agp-gradle-api)

Follow up work is tracked in
flutter#190964

This work is urgent in the sense that we are worried that android will
publish agp 10 with no opt out but not so urgent that we are willing to
break flutter users because we didn't review or understand the code
because we were in a rush.

Breaking changes are expected as part of this work. There are patterns
the android team explicitly does not want apps to use and apis that have
no equivalent.

As part of the effort to ensure this work does not slip into ai slop,
prs from this stack will be reviewed by me (@reidbaker) before asking
for review. Then we will have 2 android expert reviewers also review the
every pr.

Agent authored pr description
This is PR 1 of 11 in the AGP 9.1.0 / public `gradle-api` migration
stack.

It adds the contributor-facing and website draft documentation for the
Flutter Gradle Plugin's migration to the Android Gradle Plugin public
Variant API, which unblocks building Flutter Android apps with AGP's
`newDsl=true` enabled.

Part of flutter#180137 and flutter#166550.

…#192650)

Fixes flutter#192227

**Problem**

`AppDomain.launch` sends the `app.start` event, which carries the app
ID, before `ResidentRunner.run()` has compiled and called
`generator.accept()`. A client that acts on that ID immediately can land
an `app.restart` in the gap, producing a `recompile` against a compiler
with no accepted baseline. `frontend_server` then crashes on
`lastKnownGoodResult!`, and the app fails to start.

**Fix**

`AppDomain.restart` now waits on a new `AppInstance.started` before
entering the debounce queue, so the compiler is never asked to recompile
before it has a baseline.

**Demo**

No URLs: the bug is in the `flutter run --machine` daemon protocol, not
in rendered output, so a deployed build has no daemon to race.

Verified locally with a harness that sends `app.restart` during the
initial compile, which is the window this closes. Before, it reproduces
the exact trace from the issue and the app
dies:

    Null check operator used on a null value
#0 FrontendCompiler.writeJavaScriptBundle (frontend_server.dart:1100)
#1 FrontendCompiler.recompileDelta (frontend_server.dart:1312)
#2 listenAndCompile.<anonymous closure> (frontend_server.dart:1806)
    App failed to start

After, the restart is held until `app.started` and returns `code: 0`.

Fixes flutter#110488.

### Background: The `testWidgets` Lifecycle
Understanding this change requires distinguishing between two layers of
`Future`s and two distinct verification steps in `testWidgets`:

#### 1. Two Layers of `Future`s
* **`testBody()` Future**: The closure containing the user's test logic.
* **`runTest()` Future**: The overall async harness returned by
`binding.runTest()`. It manages the test zone, unmounts the widget tree,
and resolves only after `testBody()` and test-specific verifications
finish.

#### 2. Two Distinct Verification Phases
* **Test-specific verifications (`invariantTester`)**: Passed as a
callback to `runTest` and executed synchronously inside `_runTestBody`
immediately after the `testBody()` Future completes and the widget tree
is unmounted. In `testWidgets`, this runs
`tester._endOfTestVerifications` to verify that tickers and semantics
handles were disposed.
* **Framework-level invariant checks**: Verifies global framework state,
including ensuring foundation/rendering/widgets debug flags were reset
and no non-periodic timers or animations remain.

#### 3. The Teardown Lifecycle & Root Cause of flutter#110488
When `testWidgets` runs:
1. `testWidgets` registers `test_package.addTearDown(binding.postTest)`
with `package:test`.
2. `testWidgets` calls and returns `binding.runTest(...)`.
3. Inside `testBody()`, users may register cleanups using `addTearDown`
(for example, `addTearDown(() => debugDefaultTargetPlatformOverride =
null)`).
4. `package:test` executes teardowns in **LIFO (reverse registration)
order** only *after* the Future returned by `runTest` completes.

Previously, framework-level invariant checks ran at the end of
`_runTestBody` *before* the `runTest` Future completed. As a result,
they ran before `package:test` executed any user-registered
`addTearDown` callbacks, causing tests that clean up debug flags via
`addTearDown` to fail invariant verification (flutter#110488).

            └── reportTestException(...)                 (if Verification 2 failed)
```
### Changes & Design Rationale
#### 1. Defer Framework Invariant Checks to `postTest`

Framework invariant checks (`_verifyInvariants()`,
`_verifyAutoUpdateGoldensUnset`, etc.) are moved from `_runTestBody`
into `TestWidgetsFlutterBinding.postTest`.
Because `testWidgets` registers `binding.postTest` before running the
test body, `package:test`'s LIFO teardown ordering guarantees that all
user-registered `addTearDown` callbacks execute before
`binding.postTest`.

#### 2. Clarifying the `postTest` Error Contract

Previously, `postTest` only performed state cleanup and did not check
invariants. Moving invariant checks into `postTest` introduced the
question of how invariant failures should be propagated: allowing
`postTest` to throw, or absorbing errors and reporting them via
`reportTestException`.

We explicitly define the contract of `postTest` to **not throw
exceptions**, reporting any invariant failures via
`reportTestException`:

* **Rationale & Trade-offs**:
* *Alternative considered (throwing)*: If `super.postTest()` threw on an
invariant failure, `package:test` would still capture the failure.
However, subclasses (`AutomatedTestWidgetsFlutterBinding`,
`LiveTestWidgetsFlutterBinding`, or custom bindings) override `postTest`
to reset their own state (e.g. nulling `_currentFakeAsync` / `_clock`,
or setting `_inTest = false`). Allowing `super.postTest()` to throw
would require every subclass to defensively wrap `super.postTest()` in
`try ... finally`. If any subclass omitted this, an invariant failure
would leave the binding in a dirty state and trigger cascading `!inTest`
failures in subsequent tests.
* *Chosen approach (non-throwing)*: Absorbing errors in `postTest` and
forwarding them to `reportTestException` guarantees that all cleanup in
base and subclass implementations executes sequentially without
defensive `try ... finally` boilerplate, while still cleanly failing the
test.

**Why this does not break existing behavior:**
In the previous implementation, when invariant assertions failed inside
`_runTestBody`, they were caught by `_testZone.handleUncaughtError` and
forwarded to `reportTestException` (which delegates to
`package:test.registerException`). They never escaped `runTest` as
unhandled thrown exceptions. Catching invariant failures in `postTest`
and routing them to `reportTestException` preserves this exact error
reporting pipeline, diagnostic output, and failure semantics without
disrupting teardown execution.

#### 3. Preserving Existing Behavior on Failed Tests
(`_shouldVerifyInvariants`)

Historically, `_runTestBody` only verified invariants if the test body
did not fail:

```dart
if (_pendingExceptionDetails == null) {
  // We only try to clean up and verify invariants if we didn't already
  // fail. If we got an exception already, then we instead leave everything
  // alone so that we don't cause more spurious errors.
  ...
  _verifyInvariants();
}
```

When invariant checks are moved to `postTest`,
`_pendingExceptionDetails` is no longer available because it has already
been reported and cleared by `testCompletionHandler` when `runTest`
completed.

To preserve this exact existing behavior across the lifecycle boundary,
`_shouldVerifyInvariants` is introduced. It is set to `true` at the end
of `_runTestBody` only when `_pendingExceptionDetails == null`. If a
test fails in its body, `_shouldVerifyInvariants` remains `false`, and
`postTest` skips invariant checks—ensuring no behavior change and
preventing spurious errors (e.g. active animations on an unmounted tree)
from masking the real failure.

#### 4. Documentation Updates
Updated the doc comments on:
* `TestWidgetsFlutterBinding.postTest`: Documents the non-throwing
contract, the `@mustCallSuper` requirement, and error reporting via
`reportTestException`.
* `TestWidgetsFlutterBinding.runTest`: Clarifies the distinction between
`invariantTester` (which runs before `runTest` completes) and framework
invariant checks (which run in `postTest` after `runTest` and user
teardowns complete).

### Tests
- Added unit tests in
`packages/flutter_test/test/bindings_invariants_test.dart` verifying
that foundation variables (`debugDefaultTargetPlatformOverride`,
`debugDoublePrecision`, `debugBrightnessOverride`),
`autoUpdateGoldenFiles`, `ErrorWidget.builder`, and
`shouldPropagateDevicePointerEvents` can all be reset using
`addTearDown`.
- Added test cases verifying invariant failures in `postTest` and
ensuring invariant checks are skipped when the test body throws.

…rror 206) (flutter#194867)

When a Flutter project, SDK, or subprocess command path on Windows
exceeds `MAX_PATH` (260 characters), Win32 process and file operations
fail with OS error code `206` (`ERROR_FILENAME_EXCED_RANGE`: `The
filename or extension is too long`). Previously,
`_handleWindowsException` in `error_handling_io.dart` did not recognize
error code `206`, causing `ErrorHandlingProcessManager` and
`ErrorHandlingFileSystem` to rethrow an unhandled
`ProcessPackageException` or `FileSystemException` and trigger a crash
report.

Add `kFilenameExcedRange = 206` to `_handleWindowsException` so
operations failing with error code `206` exit cleanly with a `ToolExit`
instructing the user to move the Flutter SDK and/or project to a shorter
path or enable long paths on Windows.
