a grey box was displayed in the screen. It was not on debug mode. Only when I changed to release mode, a grey box appears.
What caused this problem? and how do I have to change?

I want to show the contents not a grey box.
CodePudding user response：
As I have commented, if you see a grey box in release mode, this means that you have some kind of error.
You should be able to view the error when running in debug mode and view the error in your console to correctly debug it. The error would be in red.
This can be any type of error, but for me, it was when I used an Expanded widget in the wrong place, I thought that I can just ignore it, but then in release mode, I had a white screen.
