MemoryPersistenceProvider class
Implementation of PersistenceProvider that uses internal memory for persistence.
Of course, once the app is stopped or cleared from memory, the internal memory is deleted and historic persistence of completed steps are lost.
This is a great implementation for testing.

Methods
-
clearStep(
String featureId) → Future< void> -
Requests that the persistence layer should remove the completion of the step
identified by
featureId.override -
clearSteps(
Iterable< String> featuresIds) → Future<void> -
Requests that the historic steps identified by
featuresIdsbe cleared from the persistence layer.override -
completedSteps(
Iterable< String?> ? featuresIds) → Future<Set< String?> > -
Returns the list of steps (as strings) that the user has previously completed from
the provided
featuresIdsset.override -
completeStep(
String? featureId) → Future< void> -
Informs the persistence layer that the user has completed the step identified by
featureId, and that it should record it in the persistence layer.override -
hasCompletedStep(
String featureId) → Future< bool> -
Returns true if the step identified by
featureIdhas completed by the user earlier, false otherwise.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
