extendedSize constant
int
const extendedSize
Number of tones in extendedTones.
In original implementation package material_color_utilities this is
defined as well, presumably for improved efficiency, but there it is set
to FlexTonalPalette.commonTones.length
. Here we instead manually set it
to compile time const of same const list length.
Flutter SDK TonalPalette has 13 tones, FlexTonalPalette extended 30.
Starting from Flutter 3.22 and FlexSeedScheme 2.0.0 the common tones should be avoided and extended tones used instead. The common tones are kept for backwards compatibility and for cases where the original M3 palette is needed. The FlexPaletteType.extended is the new default for all FlexTones.
Implementation
static const int extendedSize = 30;
