UiSpec class

A screen described as JSON, and the state it operates on.

This is a deliberately tiny vocabulary. It exists to find out how well a language model can describe a working interface, not to be a UI framework — so every node type here is one a model can hold in its head, and anything outside the vocabulary is a ProtocolException rather than a guess.

Constructors

UiSpec({required UiNode root, Map<String, String> state = const {}, String? title})

Creates a spec.

const

UiSpec.fromJson(Object? json)

Parses a decoded JSON map. Throws ProtocolException on anything it does not recognise — a generated interface that is half-understood is worse than one that refuses to render.
