Input Country → Countries, Currencies and Languages

This package provides data about countries, currencies and languages plus a selection widget (dropdown box) for each of them.

All widgets extend [FormField] so they can both be used standalone or within a [Form].

All widgets can display a flag for each selectable item and on the selection itself.
