rulesBuilder property
final
Custom rules UI in the options row. Replaces the default filter button. The expandable panel is still shown below when ItineraryRulesData.isPanelExpanded is true — use ItineraryRulesData.togglePanelExpanded from a custom button, or ItineraryRulesData.buildDefaultPanel for the default panel content.
Implementation
final ItineraryRulesBuilder? rulesBuilder;
