setup static method
Setup the screen with a context
and the size you will use.
So, if you have a design with 1280 * 720. You will pass first the context
then the design size.
Scale.setup(context, Size(1280, 720))
Implementation
static void setup(BuildContext context, Size screenSize) {
final MediaQueryData mediaQuery = MediaQuery.of(context);
_deviceScreenSize = mediaQuery.size;
size = screenSize;
}
