build method

@override Widget build(BuildContext context)

Builds the Collection widget based on the provided configuration.

This method determines the appropriate rendering strategy by examining the configuration:

• If a builder is provided and customBuilder is true, it generates a fixed number of slivers using List.generate and wraps them in MultiSliver for sliver contexts.
• If a builder is provided but customBuilder is false, it delegates to SListView.builder for standard, non-sliver list rendering.
• If no builder is used (static children), it inspects the children to check if any is a Section, Collection, or a sliver via Widget.isSliver. If sliver-compatible, it renders with MultiSliver; otherwise, it uses SListView for a scrollable list of box widgets.

This adaptive approach ensures compatibility with both sliver and non-sliver layouts, optimizing performance and preventing layout errors in scrollable parents.

Implementation

@override
Widget build(BuildContext context) {
  if (builder != null) {
    if (customBuilder) {
      return MultiSliver(
        children: List.generate(childCount!, (i) => builder!(context, i)),
      );
    }

    return SListView.builder(builder: builder);
  }

  if (children.any((element) =>
      element is Section ||
      element is Collection ||
      element.isSliver(context))) {
    return MultiSliver(children: children);
  } else {
    return SListView(
      children: children,
    );
  }
}
