How to use

Wrap your app in an Eufemia widget, and provide the EufemiaData with the palette, spacing, button and optionally darkPalette parameters:

Eufemia(
  data: EufemiaData(
    palette: EufemiaPaletteData.standard(),
    spacing: EufemiaSpacingData.fallback(),
    button: EufemiaButtonThemeData.fallback(),
    darkPalette: EufemiaPaletteData.dark(),
  ),
),

To use Material widgets, e.g. in a MaterialApp tree, use the provided adapter to provide a Material Theme:

final adapter = EufemiaThemeAdapter(context);

return MaterialApp(
  theme: adapter.theme,
  ...
);

The Eufemia provider with all the theming data can be accessed using

final eufemia = Eufemia.of(context)

Components

There are multiple UI components

Palette

This API is subject to change

The EufemiaPaletteData class is a collection of colors that are used throughout the library of components. You can create your own, or use several presets, like the saga, standard, dark and privateBanking factories.

The palette provider can be accessed using

final palette = EufemiaPalette.of(context)

Typography

If using the included themes, fonts are automatically set up. Otherwise, specify the fontFamily and package properties:

TextStyle(
  fontFamily: 'DNB Sans',
  package: 'eufemia_typography',
)

The typography provider can be accessed using

final typography = EufemiaTypography.of(context)

• extraSmall: 4.0
• small: 8.0
• medium : 16.0
• large: 24.0
• extraLarge: 32.0
