ViewState class abstract

Base class for developer-extended ViewState.

ViewState holds transient UI state — dropdown visibility, active tabs, scroll offsets, form field values — that is not tied to domain data.

This file is scaffolded once by zfa build and then preserved. The generator will never overwrite an existing ViewState file.

// SCAFFOLDED — safe to edit, never regenerated
class ProductDetailViewState extends ViewState {
  ProductDetailViewState() : super();

  final isDescriptionExpanded = Signal<bool>(false);
  final activeTabIndex = Signal<int>(0);
  final scrollOffset = Signal<double>(0.0);
}
