The code seems to reflect well, but it is not reflected on the screen. It is then reflected immediately when adjusting the size of the device screen. I can't find out what the problem is.
I want it to be reflected on the screen as soon as I run the code. I am currently using flutter. Even if I try various methods such as undock, floating, coldboot, use of different types of devices, etc., the screen will not be reflected immediately unless it is resized.
