UI::SharedControlForwarders
Defined in:
lib/ruflet/rails.rb

Overview

ViewRouter dispatches incoming page connections to the correct RufletView subclass based on the current route. It includes SharedControlForwarders so that widget helpers (text, column, safe_area, …) can be called directly inside its own rendering helpers — the same pattern showcase uses.
