Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
cancelSurvey(
) → void - Cancels the survey and resets all steps.
-
completeSurvey(
) → List< SurveyStep> - Completes the survey and returns the steps.
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
handleStepCallbacks(
SurveyStep currentStep) → Future< void> - Navigates to a specific step in the survey.
-
nextStep(
) → Future< void> - Moves to the next step in the survey and completes the survey if it's the last step.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
previousStep(
) → Future< void> - Moves to the previous step in the survey or cancels the survey if it's the first step.
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
startSurvey(
) → void - Starts the survey by pushing the SurveyScaffold page onto the navigation stack.
-
toString(
) → String -
A string representation of this object.
inherited
-
updateAnswer(
String stepId, dynamic answer) → Future< void> - Updates the answer for a specific survey step.
-
updateStepsListener(
) → void - Updates the listener for the step page controller.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
