Module: Ruflet::Extensions

Defined in:
lib/ruflet_ui/ruflet/extensions.rb,
lib/ruflet_ui/ruflet/extensions/qrcode_scanner.rb

Overview

Registry used by Ruflet extension gems to add typed Ruby controls and describe the matching Flet Flutter package. Registering a control makes its helpers available in the bare DSL, Ruflet::DSL, Ruflet, Ruflet::UI, and WidgetBuilder without editing Ruflet's generated control method tables.
