FlexTonalPalette class

A convenience class for retrieving colors that are constant in hue and chroma, but vary in tone.

This class can be instantiated in two ways:

1. of From hue and chroma. (preferred)
2. fromList From a fixed-size (FlexTonalPalette.commonSize) list of ints representing ARBG colors. Correctness (constant hue and chroma) of the input is not enforced. get will only return the input colors, corresponding to commonTones. This also initializes the key color to black.

Static Methods

createKeyColor(double hue, double chroma) → Hct

Creates a key color from a hue and a chroma. The key color is the first tone, starting from T50, matching the given hue and chroma. Key color Hct.

fromHct(Hct hct, [FlexPaletteType paletteType = FlexPaletteType.common]) → FlexTonalPalette

Create a Tonal Palette from hue and chroma of hct.

fromList(List<int> colors, [FlexPaletteType paletteType = FlexPaletteType.common]) → FlexTonalPalette

Create colors from a fixed-size list of ARGB color ints.

of(double hue, double chroma, [FlexPaletteType paletteType = FlexPaletteType.common]) → FlexTonalPalette

Create colors using hue and chroma.

Constants

commonSize → const int

Number of tones in commonTones.

commonTones → const List<int>

Commonly-used tone values.

extendedSize → const int

Number of tones in extendedTones.

extendedTones → const List<int>

Extended tone values in a FlexTonalPalette.
