## Description This attempts to re-land #142942 after being reverted in https://github.com/flutter/flutter/pull/149741 because it broke the iOS [platform view UI integration test](https://github.com/flutter/flutter/blob/master/dev/integration_tests/ios_platform_view_tests/ios/PlatformViewUITests/PlatformViewUITests.m?rgh-link-date=2024-06-06T19%3A47%3A27Z). The changes here from the original are that in the Focus widget we no longer set the `onFocus` for the `Semantics` if the platform is iOS. It was not intended to do anything on iOS anyhow. Also, I updated the matchers to not actually do anything yet with the SemanticsAction.focus matching, so that this can be landed without breaking customer tests, and once they have been updated to correctly look for the focus action, we can land a PR that will turn it on. ## Related Issues - https://github.com/flutter/flutter/issues/149838 - https://github.com/flutter/flutter/issues/83809 - https://github.com/flutter/flutter/issues/149842 ## Tests - Updated framework tests to look for the appropriate things using the matchers, even though it doesn't actually test for them yet.
