RPUITask class
This class is the primary entry point for the presentation of the Research Package framework UI. It presents the steps of an RPOrderedTask (either navigable or just linear) and then provides the RPTaskResult object.

Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onCancel → void Function(RPTaskResult? result)?
-
The callback function which has to return an RPTaskResult object.
This function is called when the participant cancels a survey. The result parameter is optional so if you don't want to do grab the result as part of the callback function you can do so, like the following:
final
- onSubmit → void Function(RPTaskResult)?
-
The callback function which has to return an RPTaskResult object.
This function is called when the participant has finished the last step.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- task → RPOrderedTask
-
The task to present. It can be either an RPOrderedTask or an RPNavigableOrderedTask.
The RPUITask presents its steps after each other and creates an RPTaskResult
object with the same identifier as the task's identifier.
