@deandreamatias can you review this one? I'll add the translations for all other languages if everything is alright

There are a lot of new validators, this is impressive!
But you can also add a dynamic value generator for the test, to increase the randomness and reliability of tests.

Can use the faker_dart package like dev_dependency and use on tests
