Rgb.from constructor

Rgb.from(Object? source)

Creates an instance of Rgb color by converting the specified source object.

If a CSS Color Module Level 3 source string is specified, it is parsed and then converted to the RGB color space. See Color.parse for examples. If a color instance is specified, it is converted to the RGB color space using Color.rgb. Note that unlike Color.rgb this method always returns a new instance, even if color is already an RGB color.

Implementation

factory Rgb.from(Object? source) {
  if (source is String) source = Color.tryParse(source);
  if (source is! Color) {
    return Rgb(double.nan, double.nan, double.nan, double.nan);
  }
  return source.rgb().copy();
}
