kun_ui_tokens 2.33.0

Generated design tokens for the KunUI design system: semantic colors, corner radius, motion curves and elevation, emitted from the same source as the web stylesheet.

kun_ui_tokens

The Dart/Flutter token layer of KunUI, the shared design system of the NextMoe/KunGal ecosystem. It is the sibling of the npm package @kungal/ui-tokens: the same generator emits the web stylesheet, this package, and a DTCG export from one in-memory model, so the two platforms cannot drift.

Component code is not shared — Flutter has no DOM and no CSS cascade, so the widgets are written separately. Tokens are shared, and they are generated.

Install

dependencies:
  kun_ui_tokens: ^2.32.1

Requires Flutter >=3.27.0: every color is a const Color.from(...), the normalised-double constructor from the wide-gamut migration.

Use

import 'package:flutter/widgets.dart';
import 'package:kun_ui_tokens/kun_ui_tokens.dart';

final scheme = MediaQuery.platformBrightnessOf(context) == Brightness.dark
    ? KunColors.dark
    : KunColors.light;

Container(
  decoration: BoxDecoration(
    color: scheme.primary.solid,
    borderRadius: BorderRadius.circular(KunRadius.md),
    boxShadow: KunShadows.md,
  ),
  child: Text('Kun', style: TextStyle(color: scheme.primary.onSolid)),
);

AnimatedContainer(
  duration: KunDurations.base,
  curve: KunEasing.standard,
  // ...
);

There is deliberately no KunTheme here. This package is theme-system agnostic — plain const holders, no ThemeExtension, no Material coupling — so the eventual widget layer stays free to pick its own theming model.

Guarantees

• Contrast. Every onSolid clears WCAG AA (≥ 4.5:1) against its solid in both modes. The generator asserts it and exits non-zero otherwise, so an illegible pair cannot reach a release.
• Parity. Colors are sRGB-clamped OKLCH, the same clampChroma pass the CSS goes through, so an app and the websites render the same color.
• Version lockstep. This package's version always equals the version of the four @kungal/* npm packages. 2.32.1 here is 2.32.1 there.
