jet_cad_2d_plan 1.0.2

The plan library for jet_cad_2d: a plan controller and composable design-mode widgets over kits that contribute types, tools and symbols.

example/main.dart

// PlanEditor over an empty plan with no kit: the plan library's own tools,
// the layers and the page; a button in each bar switches to the service
// mode and back. Run from the package directory with
// `flutter run -t example/main.dart`.
