How do you properly configure window management for a Flutter desktop app, such as setting an appropriate initial window size, a genuinely reasonable minimum size, or a specific custom window title?

The window_manager package lets you programmatically control several important native desktop window properties that simply do not exist at all in a mobile context, including setting an appropriate specific initial window size and position when your app first actually launches, enforcing a genuinely reasonable minimum window size to help meaningfully prevent your particular layout from ever breaking down at an excessively small size, and dynamically updating the window's own title bar text to actually reflect the user's currently active specific document or screen.

await windowManager.setMinimumSize(Size(800, 600));
await windowManager.setTitle('My App - Document 1');
