Renderer class

Core rendering engine for MCP UI DSL

Constructors

Renderer({required WidgetRegistry widgetRegistry, required BindingEngine bindingEngine, required ActionHandler actionHandler, required StateManager stateManager, dynamic engine, RenderInspector? widgetWrapper})

Properties

actionHandler → ActionHandler

final

bindingEngine → BindingEngine

final

definitionResolver ↔ Future<Map<String, dynamic>> Function(String ref, Map<String, dynamic> origin)?

Resolver the view widget uses to fetch a definition from an origin (spec v1.4 §6.11, Composition Profile). Held here rather than on a single context because root contexts are created on demand — stamping it in createRootContext is what makes it reach every tree, and RenderContext.createChildContext carries it the rest of the way.
