I have developed an app for windows in flutter, when I run it on my platform, things work fine. But as soon as I run it on some other machine or the client’s machine, there is a problem in the alignment of some buttons and containers.

I am not sure what is going wrong. I have followed each step from this guide

If anyone has ever faced this issue before, request you to please help me.
