Feature request: global enabled property

[jan-siroky]

Hi,

Thank you for your hard work.

I have a project where I would like to reuse mobile UI but without ScreenUtil functionality, would you be willing to add bool property to ScreenUtil widget which would allow us to disable / enable ScreenUtil functionality in the app?

e.g.

ScreenUtil(enabled: MediaQuery.sizeOf(context).width < 500, ...

Thank you for consideration!
