swatchContainsColor static method

bool swatchContainsColor(
  1. ColorSwatch<Object> swatch,
  2. Color color
)

Returns true if the swatch contains color.

Used by the ColorPicker to help reduce rebuilds in certain cases. But you can also use it as help to determine if a color belongs to a given ColorSwatch.

Implementation

static bool swatchContainsColor(ColorSwatch<Object> swatch, Color color) {
  // We use index list with 850 index included to check all possible indexes
  // in any swatch/ use case that might be used. This covers normal primary,
  // primaries with the 850 index, and via primary also accent index.
  for (final int i in _indexPrimaryWith850) {
    if (swatch[i] == color || swatch[i]?.value32bit == color.value32bit) {
      return true;
    }
  }
  return false;
