研究方向
Start in src/platform/windows/application_windows.cpp and trace Application::Quit() through the window teardown and message-loop handling. Check the behavior in a Flutter app, including a close handler that intercepts the system close button. Done means the windows and Flutter engine are destroyed while messages are still pumped, before WM_QUIT is posted, and the app exits promptly.

描述
On Windows, Application::Quit() ends in PostQuitMessage() (src/platform/windows/application_windows.cpp) without destroying the application's windows first.
window_manager had the same pattern in destroy(), and there it made apps take several seconds to exit, or stop responding, since Flutter 3.24. The window and the Flutter engine were torn down after the message loop had already stopped.
Expected: destroy the windows (so the Flutter view controller shuts down its engine while messages are still pumped), then post WM_QUIT. Needs checking in a Flutter app, including with a close handler that intercepts the system close button.
Background:
