sections method

List<Section> sections({
  1. bool includeExiting = false,
})

Section payloads in render order. Excludes sections currently mid-exit-animation unless includeExiting is true. The live form is the input shape reorderSections implicitly expects (via the keys returned by sectionKeys).

Implementation

List<Section> sections({bool includeExiting = false}) {
  _checkNotDisposed();
  final keys = includeExiting ? _tree.rootKeys : _tree.liveRootKeys;
  final out = <Section>[];
  for (final k in keys) {
    if (!_assertIsSection(k)) {
      continue;
    }
    final node = _tree.getNodeData(k);
    if (node == null) {
      continue;
    }
    final data = node.data;
    if (data is SectionPayload<Section, Item>) {
      out.add(data.value);
    }
  }
  return out;
}
