You can open the following "file" in Xcode:

YOUR_PROJECT/macos/Runner.xcworkspace

and locate the following file within the opened Xcode project:

From there you can select this entry in the secondary sidebar:

Then you can edit the window's property in the right sidebar, including disabling window control buttons. disable all three and the buttons are gone.

Note that when I tried it myself things got a lil bit wonky regarding the window so perform this at your own risk.
