bottomNavigationBuilder property
Builds a replacement for the default bottom navigation of the task.
When null the default row is shown — a BACK button in a navigable task
and a NEXT button, configured through nextButtonText and
nextButtonStyle. Those two are ignored when a builder is supplied, since
the builder owns the whole row.
Return const SizedBox.shrink() to remove the row entirely.
The default row hides itself on the steps which carry their own buttons (RPCompletionStep, RPVisualConsentStep and RPConsentReviewStep); the builder is called on every step instead, with RPTaskNavigation.currentStep telling it which one is on screen.
Implementation
final RPBottomNavigationBuilder? bottomNavigationBuilder;
