No source file, test, or reproduction steps are identified. Start by reproducing the first-launch behavior on both platforms with Flutter SDK 3.7.12 and FlutterBoost 4.4.0, focusing on the window.physicalSize entry point. Done means the reported physicalSize values are correct instead of 0.0 by the time the shown output is produced.
