Implementation

bool executeHandleEnter(FluentDocument document) {
  if (document.registry.dispatchEnter(document)) return true;
  final cursor = document.cursor;

  if (!cursor.isCollapsed) {
    executeHandleReplaceSelection('', document);
  }

  final container = document.findLogicalContainerCached(cursor.anchorId);
  if (container == null) return false;

  if (container is Link) {
    return _handleLinkEnter(document, container);
  }

  if (container is Paragraph) {
    final ancestorItem = findAncestorCached<ListItem>(document, container);
    if (ancestorItem != null) {
      return _handleListEnter(document, ancestorItem, container);
    }
    final ancestorCell = findAncestorCached<FluentCell>(document, container);
    if (ancestorCell != null) {
      return _handleCellEnter(document, ancestorCell);
    }
  }

  return _handleParagraphEnter(document, container);
