This should already be possible by handling the WM_CLOSE window message. See:

• Example app that handles WM_CLOSE: https://github.com/timsneath/win32/blob/6f1b25c74f8a56fa62ce0c463f2d70be33feb822/example/notepad/notepad.dart#L224-L228
• WM_CLOSE docs: https://docs.microsoft.com/en-us/windows/win32/winmsg/wm-close
