showColorCode property Null safety
Set to true to show the RGB Hex color code of the selected color.
The color code can be copied with copy icon button or other enabled copy actions in the color picker. On the wheel picker the color code can be edited to enter and select a color of a known RGB hex value. If the property colorCodeReadOnly has been set to false the color code field can never be edited directly, it is then only used to display the code of currently selected color.
Defaults to false.
