fixes #112207 ## What's new? - Added a `view_id` on `UpdateSemantics` - Added a `view_id` on `DispatchSemanticsAction` - Piped the `view_id` all over creation - Updated tests for these actions across the different platforms - Added `FlutterEngineSendSemanticsAction` to the embedder API in order to not break `FlutterEngineDispatchSemanticsAction` - Using this view ID properly on the Windows platform (see `engine/src/flutter/shell/platform/windows/flutter_windows_engine.cc`) ## How to test 1. Checkout [foundation-plus-framework](https://github.com/canonical/flutter/pull/36) from canonical/flutter 2. Merge this branch into it 3. Enable the "Narrator" screen reader on windows 4. Run the Multi window reference app (see [PR](https://github.com/canonical/flutter/pull/36) for details) 5. Open up another window, and note that the right buttons and things are being highlighted, as the screenreader would expect 🎉 ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
