Description

Migrate all iOS example apps to UIScene lifecycle and add UIScene support to firebase_auth.

Example apps (17 apps + tests app):

  • Added UIApplicationSceneManifest to all Info.plist files with FlutterSceneDelegate
  • ObjC apps: updated AppDelegate to use FlutterImplicitEngineDelegate pattern (plugin registration via didInitializeImplicitFlutterEngine:)
  • Swift apps: no AppDelegate changes needed (Flutter handles migration)

firebase_auth plugin:

  • Added FlutterSceneLifeCycleDelegate conformance (conditional, backwards-compatible)
  • Added addSceneDelegate: registration in registerWithRegistrar:
  • Added scene:openURLContexts: for OAuth/custom-scheme redirects under UIScene
  • Fixed presentationAnchorForAuthorizationController: to use scene-aware window lookup instead of deprecated UIApplication.keyWindow
