Not working, I dont know why?

It's not working. I have used your both file as it is. Unfortunately, I am getting a blue screen only. Even I had pressed the FAB button and it's showing true/false value but it's not working for snowflow.

It's not working at all.. it just shows one white dot on top-left corner of the screen.. But it does not move over the screen.

Inside LayoutBuilder, remove if(_snows == null)(But do not delete the statement inside if statement!) then it will work.
