materialName static method

String materialName(Color color, { Map<ColorSwatch<Object>, String>? colorSwatchNameMap, bool withIndex = true, })

Returns the Material swatch name or custom color swatch name for a given color.

The name will include the color index if the flag withIndex is true. If the given color is not a material color or one of the accents colors, an empty string is returned. The function can also take as input an optional custom color swatch to name map and return a custom name for any color found in any of the custom color swatches in the map.
