TonalPalette class Null safety

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 (TonalPalette.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.

Properties

asList → List<int>
Returns a fixed-size list of ARGB color ints for common tone values.
