Provides information about the screen that can be used to your liking
An instance can be created via a builder in MaterialApp so you can
use it globally and have the screen information wherever you want.
It helps to be able to use the sizes by means of screen percentages in an easy way
and using only the MediaQuery through the BuildContext but without having to create
an instance of MediaQuery or having to use it directly by writing it completely.
For example you can use 20.h(context) and you are automatically pointing to MediaQuery.of(context).size.height * 20
