associatedUnit property
The unit that's associated with this channel.
Some channels are typically written without units, while others have a specific unit that is conventionally applied to their values. Although any compatible unit or unitless value will work for input¹, this unit is used when the value is serialized or returned from a Sass function.
1: Unless LinearChannel.requiresPercent is set, in which case unitless values are not allowed.
Implementation
final String? associatedUnit;
