As explained in the linked issue above, interact with the flutter UI on top of the platform view. Notice that the platform view still receives the touches, despite that the platform view is under flutter UI and it shouldn't receive the touches. This only happens on iOS 26.

### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)
When building through Xcode, if you previously ran from a different build mode (debug, profile, release), it will show a warning (or error if archiving) that you need to run a Flutter command to have the correct build settings. This is no longer required.

### Impact Description:
This affects apps like the one in https://github.com/flutter/flutter/issues/174100 that render Cupertino widgets which use superellipses. The app may show flickering or other artifacts when rendered with Impeller (particularly on the GLES back end).
### Workaround:
Disable Impeller
### Risk:

### Risk:
What is the risk level of this cherry-pick?
### Test Coverage:

### Validation Steps:
The crash does not happen consistently. One way that I have been able to reproduce it is:
* run Gallery with Impeller/Vulkan on a slow phone
* scroll through the Shrine screen and start a lot of image decodes
* quickly exit the app before the decodes have completed
Without the fix, the app will often crash if an image decode tries to access the Vulkan context after it was partially shut down while exiting the app.

On Android builds that do not use flutter.minSdkVersion and do use a value lower than 24 in a kotlin build file, correct flutters auto migration to update value with kotlin syntax. https://github.com/flutter/flutter/pull/173825
### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)
3.35 bumped the min android api level to api 24. We have an auto migrator to handle if users did not use flutter.minSdkVersion and did set an integer to auto update. The auto update logic produces a syntax error in kotlin build files but the matcher matches kotlin build files. CP is a good idea because 3.35 users are the most likley to be impacted.

When running on Windows, `flutter widget-preview start` eventually crashes due to an unhandled exception from the Windows file system watcher that should not be considered fatal.
### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)
Given enough time, the file system watcher backing the `WindowsDirectoryWatcher` instance will add an error to the stream with the `Directory watcher closed unexpectedly` message. The `WindowsDirectoryWatcher` restarts the backing file system watcher, but if the event stream doesn't have an error handler registered, the tool crashes due to the unhandled exception.

(cherry picked from commit 4abea340e19db0c8cf2df804104335a503e37ec0)
Fixes of #171992 for the stable branch.
Cherry-pick of [https://github.com/flutter/flutter/pull/173807](https://github.com/flutter/flutter/pull/173807) onto stable.
**Impacted Users**
Developers and end-users of Flutter applications running on Samsung Galaxy S10 or Note 10 series devices equipped with Exynos 9820/9825 SoCs.
**Impact Description**
Due to malfunctioning Vulkan drivers on these SoCs, platform views that rely on `SurfaceView` fail to render correctly. The original PR addresses this by blocklisting the affected SoCs, forcing them to use Impeller with OpenGL ES instead of Vulkan.
**Workaround**
Aside from setting `io.flutter.embedding.android.ImpellerBackend` (which is not available in production) or disabling Impeller entirely, there is no practical workaround for this issue on affected devices.
**Risk**
The risk of this cherry-pick is low. The original PR only adds specific SoCs to the blocklist and renames a static variable, which does not affect other devices regardless of whether they use this mechanism.
**Test Coverage**
Due to the nature of the issue and the fix, validation can only be performed through manual testing on the affected devices. As the reporter of the original issue, I have verified the fix on the Galaxy S10 5G(SM-G977N, Exynos 9820), confirming that the change resolves the rendering problem.
**Validation Steps**
1. Create a test Flutter app that uses a platform view with `SurfaceView` (e.g., [https://github.com/bc-lee/test-flutter-android-texture](https://github.com/bc-lee/test-flutter-android-texture) or [https://github.com/gaaclarke/surface_platformview](https://github.com/gaaclarke/surface_platformview)).
2. Run the app on the targeted devices.
3. Verify that the application renders correctly without graphical issues.

Fixes https://github.com/flutter/flutter/issues/173959
This is a top-10 crasher on `3.35.{0,1}`, but the underlying preview detection logic has been completely rewritten since the stable branch cut.

Cherry pick of https://github.com/flutter/flutter/pull/173602
Impacted users: All Linux users of Flutter
Impact Description: Due to calling gtk_window_redraw on a Flutter thread a lock up may occur. The Flutter app will then become unresponsive.
Workaround: No workaround
Risk: Low - fix is to run the GTK call on the GTK thread which is what the correct behaviour should be.
Test coverage: Rendering covered by existing tests, use of thread not explicitly tested, but https://github.com/flutter/flutter/issues/173660 opened to add this in future.
Validation Steps: Run test program in https://github.com/flutter/flutter/issues/173447 which generates many frames and maximizes the chance of a lock up.
Updates Dart has for 3.35 stable release to Dart 3.9 hash -- https://dart.googlesource.com/sdk/+/54588cb8088890ea08fe1a31b95efe478a4609b5.
Steps I took:
1. Updated hash to desired version.
2. Run `engine/src/tools/dart/create_updated_flutter_deps.py -f DEPS` to update any Dart dependencies if needed (none updated).
3. Updated `engine/src/flutter/ci/licenses_golden/licenses_dart` with diff produced in error from https://ci.chromium.org/ui/p/flutter/builders/try/Linux%20linux_license/36032/overview build failure.
