Merged
Conversation
iOS 27 terminates apps that have not adopted the UIScene lifecycle, and Flutter 3.47 enforces AGP/Kotlin minimums this project was below, so the Android build failed outright. - iOS: adopt UIScene (UIApplicationSceneManifest + FlutterImplicitEngineDelegate) - iOS/macOS: drop use_modular_headers!, raise platforms to 15.0 / 12.0 - Android: AGP 8.10.1 -> 8.11.1, Kotlin 2.1.0 -> 2.2.20, Gradle 8.11.1 -> 8.14 (AGP 8.11 requires Gradle >= 8.13) - Android: use flutter.ndkVersion, Java 17 Verified: Android APK, iOS simulator and macOS all build; app launches on the iOS 27 simulator.
