Question

How do I minimize the window or open it to full screen using the code?
I want to implement a beautiful top panel of the application using the "window drag area" ([https://flet.dev/docs/controls/windowdragarea/#app-window-without-a-title-that-can-be-moved]), but the problem is that I can't find more than one mention in the documentation about extending the window to the full screen and combining it with the code.
If it is somehow possible to do this, explain how. 🙏

In documentation you have the respective properties for Page control to handle the window.

with "page.window_minimized = True" you can minimize your window
with "page.window_maximized = True" you can maximize your window to full screen
