## **BREAKING CHANGE** Adopting Apple's UISceneDelegate protocol shifts the initialization order of apps. For the common cases we've made sure they will work without change. The one case that will require a change is any app that in `-[UIApplicateDelegate didFinishLaunchingWithOptions:]` assumes that `UIApplicationDelegate.window.rootViewController` is a `FlutterViewController` instance. Users should follow the [migration guide](https://docs.google.com/document/d/16WsqYbANmhupw-gxGPQPZ9B3yz1YBIviS-N1UyIQNSE/edit?tab=t.0#heading=h.txry2otwqko3) to update that usage. ## Changes since revert It's been rebased onto the FlutterPluginRegistrant PR which was used for migration. The dynamic selection of the UISceneDelegate has been removed, instead there is a flutter tool migration to the Info.plist. ## Description fixes: https://github.com/flutter/flutter/issues/167267 design doc: https://docs.google.com/document/d/1ZfcQOs-UKRa9jsFG84-MTFeibZTLKCvPQLxF2eskx44/edit?tab=t.0 relands https://github.com/flutter/flutter/pull/168396 relands https://github.com/flutter/flutter/pull/168914 relands https://github.com/flutter/flutter/pull/169276 ## 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.
