Config file

[FMorschel]

Maybe creating possible edits on snippets through the config file would be interesting.

Looking over #41 and my own experience using the use_super_parameters linter on my projects, for example, I would like to be able to use the statelessW and statefulW with the constructors starting with Name({super.key}).

Maybe adding the comma at the end by default on the constructors, making them const, removing BuildContext from the builder
at StatefulBuilder snippet (as suggested by avoid_types_on_closure_parameters linter), or any of these little changes.

And for the #41 maybe a property where you set whether this project uses null-safety or not.

Maybe even change the "always Container" rule for something like a const SizedBox.shrink() or something else chosen by the project owners.
