3.38.0

Flutter 3.38 enhances developer productivity through Dart dot shorthands, improved web development configuration, and expanded Widget Previews with IDE integration. Critical platform updates include mandatory UIScene lifecycle migration for iOS, 16 KB page size support for Android, and support for iOS 26 and Xcode 26. The framework gains more granular UI control via OverlayPortal improvements, predictive back gestures on Android, and robust sliver-based scrolling fixes.
