FlexCorePalette class
An intermediate concept between the key color for a UI theme, and a full color scheme. Five tonal palettes are generated, plus a default error palette if not provided.
This is a modification of package:material_color_utilities CorePalette, to make it possible to create Material-3 seeded ColorScheme using tonal palettes created from 6 different ARGB seed colors, where 5 are optional. As an addition to using only one as provided via material_color_utilities version CorePalette.of and here also via FlexCorePalette.of.
This implementation also has an unnamed constructor for the six main final FlexTonalPalette properties. It also exposes the original version's private constructor FlexCorePalette.fromHueChroma, that is used by FlexCorePalette.of.
It adds a FlexCorePalette.fromSeeds constructor to enable creating the FlexTonalPalettes for primary, secondary and tertiary, error, neutral and neutralVariant color groups, called palettes using optional ARGB seed colors, for secondary, tertiary, error, neutral and neutralVariant FlexTonalPalettes, instead of tying them down to same ARGB seed color used for the primary color group.
The core produced tonal palettes are primary, secondary, tertiary, neutral, neutralVariant and error.

Constructors
- FlexCorePalette.new({required FlexTonalPalette primary, required FlexTonalPalette secondary, required FlexTonalPalette tertiary, required FlexTonalPalette neutral, required FlexTonalPalette neutralVariant, FlexTonalPalette? error})
-
Creates a FlexCorePalette by providing FlexTonalPalettes for each
tonal color palette in the Material 3 core palettes.
const
- FlexCorePalette.fromHueChroma(double hue, double chroma, [FlexPaletteType paletteType = FlexPaletteType.common])
- Create a standard Material 3 core tonal palette from Hue and Chroma.
-
FlexCorePalette.fromList(List<
int> colors, [FlexPaletteType paletteType = FlexPaletteType.common]) - Create a FlexCorePalette from a fixed-size list of ARGB color ints representing concatenated tonal palettes.
- FlexCorePalette.fromSeeds({required int primary, int? secondary, int? tertiary, int? error, int? neutral, int? neutralVariant, double? primaryChroma, double? primaryMinChroma, double? secondaryChroma, double? secondaryMinChroma, double? tertiaryChroma, double? tertiaryMinChroma, double? tertiaryHueRotation, double? neutralChroma = 4, double? neutralMinChroma, double? neutralVariantChroma = 8, double? neutralVariantMinChroma, double? errorChroma, double? errorMinChroma, FlexPaletteType paletteType = FlexPaletteType.common, bool useCam16 = true, bool respectMonochromeSeed = false})
-
Create a FlexCorePalette from one to three seed colors.
