Implementation

@override
void visitElementAfter(MarkdownElement element) {
  final current = _tree.removeLast();
  final type = current.type;
  final parent = _tree.last;
  final builder = _builders[type]!;

  final textSpan = builder.createText(current, parent.style);
  if (textSpan != null) {
    current.children.add(createRichText(textSpan));
  }

  current.children.replaceRange(
    0,
    current.children.length,
    compressWidgets(current.children),
  );

  final widget = builder.buildWidget(current, parent);
  final isBlock = builder.isBlock(current);
  if (widget != null) {
    // Add spacing between block elements
    _tree.last.children.addIfTrue(
      SizedBox(
        height: _blockSpacing,
        // TODO(Zhiguang): Remove it when this issue is fixed:
        // https://github.com/flutter/flutter/issues/104548
        child: selectable
            ? const Text(' \n', selectionColor: Colors.transparent)
            : null,
      ),
      isBlock && _tree.last.children.isNotEmpty,
    );

    if (widget is InlineWraper) {
      parent.children.addAll(widget.children);
    } else {
      if (!isBlock) {
        _checkInlineWidget(widget);
      }

      parent.children.add(widget);
    }
  }

  if (_keepLineEndingsWhen == type) {
    _keepLineEndingsWhen = null;
  }

  _gestureRecognizers.remove(type);
