ui_schema library
A tiny JSON vocabulary for describing a Flutter screen, and a renderer for it — a proof of concept for having a language model build an interface.
Import this only if you want it: it is deliberately a separate library from
package:chatgpt_free/chatgpt_free.dart, so a consumer who just wants the
chat client never sees any of it.
