调研方向
从三个指定包中的 example/ios/Runner/Info.plist 开始，将它们的场景配置与 issue 中列出的、已能在 iOS 27 上启动的 iOS 示例进行比较。为每个受影响的示例添加所需的 UIApplicationSceneManifest，然后在 iOS 27 模拟器上重新运行 ios_platform_tests 的 native test 步骤。三个示例应用都能启动且其原生测试均通过，即为完成。
由索引模型根据 Issue 内容生成。
描述
Three flutter/packages iOS example apps crash at launch when their native tests run on the iOS 27 simulator with Xcode 27, so the native test step of ios_platform_tests fails for them:
google_maps_flutter_ios_sdk9/example— shard 2: https://ci.chromium.org/b/8668086846834062161google_maps_flutter_ios_sdk10/example— shard 2: same buildwebview_flutter_wkwebview/example— shard 5: https://ci.chromium.org/b/8668086842838050321
(Both are staging.shadow led replays with sdk_version: 27a266a; the earlier Xcode 27 runs behind #194019 never reached this step because xcode analyze deprecation failed first.)
Application failed to launch: UIScene life cycle is required for apps built with this SDK. See "Transitioning to the UIKit scene-based life cycle" in the UIKit documentation for more information on migration.
The test runner crashed before establishing connection: Runner
For the two google_maps examples all four GoogleMapsUITests fail with dev.flutter.plugins.googleMobileMapsExample crashed, then the unit-test host hits the same error. For webview_flutter_wkwebview the UI tests pass but the unit-test Runner host fails to launch.
Cause: these are the only iOS example apps in the repo whose example/ios/Runner/Info.plist has no UIApplicationSceneManifest. iOS 27 requires the scene-based life cycle for apps built against its SDK (same root cause as #187870 on the framework side). The other iOS examples (google_maps_flutter_ios, google_sign_in_ios, in_app_purchase_storekit, camera_avfoundation, image_picker_ios, url_launcher_ios, video_player_avfoundation, …) already have the manifest and launch fine on iOS 27.
