extractComponentRefs function

Set<ComponentRef> extractComponentRefs(FFNode node)

Extract structured component references from a node tree.

Returns both local component keys (libraryProjectId is null) and library component references (libraryProjectId is non-null).

Implementation

Set<ComponentRef> extractComponentRefs(FFNode node) {
  final refs = <ComponentRef>{};

  void traverse(FFNode current) {
    if (current.isComponent && current.hasComponentClassKeyRef()) {
      final keyRef = current.componentClassKeyRef;
      final depId = keyRef.dependencyProjectId;
      refs.add((
        key: keyRef.key,
        libraryProjectId: depId.isEmpty ? null : depId,
      ));
    }
    for (final child in current.children) {
      traverse(child);
    }
  }

  traverse(node);
  return refs;
}
