Moon Design System

Note: This project uses Release Please and Conventional Commits spec, please follow the conventions or consider using Commitizen to write commit messages.

Disclaimer

The current major release, v1.0.0, will be maintained as-is and will not receive further updates, except for patches. The v1 theming is based on the soon-to-be deprecated Moon Design Figma v1 and lacks flexibility. For greater control over theming with v1 of moon_flutter, it is recommended to create custom wrapper widgets around the moon_flutter widgets that align with your project's specific theming requirements.

There is ongoing background work for v2 which aims to be more modular, scalable and themable.

Applying theming and overrides

• Declare tokens variable and optionally override values:

final lightTokens = MoonTokens.light.copyWith(
  colors: MoonColors.light.copyWith(
    piccolo: Colors.blue,
    textPrimary: Colors.amber,
  ),
  typography: MoonTypography.typography.copyWith(
    heading: MoonTypography.typography.heading.apply(
      // Using variable font and bumping down the font weight compared to the
      // baseline 600 for heading.
      fontFamily: "DMSans",
      fontWeightDelta: -1,
      fontVariations: [const FontVariation('wght', 500)],
    ),
  ),
);

final lightTheme = ThemeData.light().copyWith(
    extensions: <ThemeExtension<dynamic>>[MoonTheme(tokens: lightTokens)],
  );

• Or if needed override widget theming:

final lightTheme = ThemeData.light().copyWith(
  extensions: <ThemeExtension<dynamic>>[
    MoonTheme(tokens: lightTokens).copyWith(
      accordionTheme: MoonAccordionTheme(tokens: lightTokens).copyWith(
        colors: MoonAccordionTheme(tokens: lightTokens).colors.copyWith(
              backgroundColor: Colors.green,
            ),
      ),
    ),
  ],
);

• Apply the declared theme:

return MaterialApp(
      title: 'Moon Design System example',
      theme: lightTheme,
      home: const HomePage(),
 );
