Description

Hello!

Flutter is migrating to UIScene life cycle for iOS. Please add UIScene lifecycle support to your plugin.

Apple will require the UIScene life cycle in their next release. To remain compatible, Flutter will eventually require plugins to support the UIScene life cycle.

How to add UIScene life cycle support to your plugins
You can find the migration guide here: https://docs.flutter.dev/release/breaking-changes/uiscenedelegate#migration-guide-for-flutter-plugins

Why

Why is Flutter migrating to the UIScene life cycle?
Apple announced that: “In the release following iOS 26, any UIKit app built with the latest SDK will be required to use the UIScene life cycle, otherwise it will not launch.”

To ensure iOS Flutter applications remain compatible and launch successfully on future iOS releases, a migration is required.

AI Summary: Users request adding UIScene lifecycle support for iOS. This is crucial for future compatibility with Flutter and upcoming Apple OS requirements, preventing app launch failures.

The plugin doesn't involve the lifecycle management, thus the migration is not applicable.

Hello, like this,"UIApplication.sharedApplication.keyWindow" Here used Deprecated API，which may cause get window exception

If it doesn't involve the lifecycle management, can we remove the use of addApplicationDelegate and applicationWillTerminate? Now it has been detected by AI and cloned for modification.
