SeedColorScheme extension

Extension on ColorScheme to provide a more flexible alternative to Flutter's Material 3 ColorScheme.fromSeed.

Use this extension to make a seeded ColorScheme using separate key colors for primary, secondary, tertiary, error, neutral and neutral variant color groups in ColorScheme.

By providing a FlexTones you can also customize tone mapping from tonal palettes to ColorScheme color and key color chroma usage per key color, used by the Material 3 tonal palette creation HCT (Hue-Chroma-Tone) color space algorithm.

As with ColorScheme.fromSeed, prefer using same key colors when seed generating your light and dark ColorScheme to create a balanced and matching light and dark scheme.
