How can I run a Flutter Linux desktop application in full screen?

Question

I need to run a Flutter Linux application in full screen, how can this be achieved? I've looked at the WindowUtils plugin but it only supports desktop embedding.

On Linux, Flutter runs above GTK, so you may edit the file linux/my_application.cc and replace the following line:

gtk_window_set_default_size(window, 1280, 720);

with this line:

gtk_window_fullscreen(GTK_WINDOW(window));
