collectInlineImages function

List<FluentImage> collectInlineImages(InlineContainerNode container)

Collects FluentImage in visitation order (both direct and those inside Link). Must produce the same order used by _buildTextSpanAndTrackPositions, so the placeholder index aligns the child RenderBox.

Implementation

List<FluentImage> collectInlineImages(InlineContainerNode container) {
  final result = <FluentImage>[];
  void visit(FNode node) {
    if (node is FluentImage) {
      result.add(node);
      return;
    }
    if (node is Link) {
      for (final child in node.getChildren()) {
        if (child is FluentImage) result.add(child);
      }
      return;
    }
    if (node is FluentList) return;
    if (node is InlineContainerNode) {
      for (final child in (node as InlineContainerNode).getChildren()) {
        visit(child);
      }
    }
  }
  for (final child in container.getChildren()) {
    visit(child);
  }
  return result;
}
