SuperFormField class

Base widget for SuperFormFields like TextSuperFormField.

These are also referred as field controlling widgets since they register fields, thus requiring name and rules.

It is fine to implement your own fields without extending this widget especially when you wrap stateless widgets, but utilities provided by this state might be helpful when implementing more complicated controls.
