# halkyon_shared Shared Dart packages across Halkyon apps, a pub workspace: - [`halkyon_ui`](packages/halkyon_ui): Halkyon's look, the theme, fonts, layout and shared widgets (Flutter). - [`halkyon_core`](packages/halkyon_core): low-level primitives (pure Dart). - [`halkyon_interop`](packages/halkyon_interop): cross-app contracts (pure Dart). Dart 3.13 and Flutter 3.47, with LeanCode's lints (`leancode_lint`), configured once in `analysis_options.yaml` here, which every package includes: its analyzer plugin only reaches packages of a workspace from the root. Run `flutter pub get` and `dart analyze --fatal-infos` here, and each package's tests in its folder (`dart test`, or `flutter test` for `halkyon_ui` and its example). Apps take a package by git, pinned to a signed commit; see [`halkyon_ui`'s README](packages/halkyon_ui/README.md).
