RPActivityStep class

A concrete subclass of RPStep that represents a step in which a single Activity is presented to the user.

When a Task Widget presents an RPActivityStep object, it instantiates an RPUIActivityStep object to present the step. The actual visual presentation depends on the type of RPActivityStep (e.g. RPTrailMakingActivity from the cognition_package Flutter package).

jsonType String
Return the __type to be used for JSON serialization of this class. Default is runtimeType. Only specify this if you need another type.
no setterinherited
optional bool
Can this step be skipped? If so, the result for the step will be null.
