class UIColorclass

class MappedValue

A class that represents a derived color or gradient value.

class MappedValue;

Notes

• Use UIColor.mappedValue() to create instances of this class.
• Use map() to derive a new instance from the resolved value.
• Results are cached and invalidated when the color registry changes (e.g. along with the theme).

Examples

UIColor.mappedValue("background", bg =>
    UIColor.isBrightColor(bg as UIColor)
        ? UI.colors.white
        : UIColor.linearGradient(180, darkGray, black)
)

Constructor

• new UIColor.MappedValue()
  Creates a new MappedValue instance.

Instance members

• resolve()
  Returns the resolved background value.
• map()
  Returns a new MappedValue that transforms the resolved source value.
