@alihassan143 Should I merge previous the PR first or these two are unrelated?

[alihassan143]

@LucasXu0 this pr is different and other pr is different

[alihassan143]

@you can first merged this pr other pr just need to be rebase and resolve conflicts

[alihassan143]

@LucasXu0 first merge this pr than merge copy paste pr

[LucasXu0]

the href is missing here.

[alihassan143]

@LucasXu0
href logic implemented in that way because popular editor do the same
Lexical Editor
Tiny Editor
Quill Editor

[alihassan143]

@LucasXu0 @Xazin now this pr ready to be merged

[LucasXu0]

@alihassan143 Please move this code to a new function.

Before

    // rich editor for webs do this so handling that case for
    //  href <a href="https://www.google.com" rel="noopener noreferrer" target="_blank"><strong><em><u>demo</u></em></strong></a>
    if (attributes[AppFlowyRichTextKeys.href] != null) {
      final element = dom.Element.tag(HTMLTags.anchor)
        ..attributes['href'] = attributes[AppFlowyRichTextKeys.href];
      dom.Element? newElement;
      dom.Element? appendElement;

      attributes.forEach((key, value) {
        if (key != AppFlowyRichTextKeys.href) {
          if (newElement == null) {
            newElement = convertSingleAttributeTextInsertToDomNode(
              text,
              {key: value},
            );
          } else {
            appendElement ??= convertSingleAttributeTextInsertToDomNode(
              "",
              {key: value},
            );

            if (appendElement != null) {
              appendElement = appendElement!..append(newElement!);
            } else {
              appendElement = convertSingleAttributeTextInsertToDomNode(
                "",
                {key: value},
              );
            }
          }
        }
      });
      if (appendElement != null) {
        element.append(appendElement!);
      } else if (newElement != null && appendElement == null) {
        element.append(newElement!);
      }

      return element;
    }

After

  dom.Element convertMultipleAttributeTextInsertToDomNode(
    String text,
    Attributes attributes,
  ) {
   // handle the href logic 
   final element = new_function_name(textInsert);
   if (element != null) {
     return element;
   }
    final span = dom.Element.tag(HTMLTags.span);
    final cssString = convertAttributesToCssStyle(attributes);
    if (cssString.isNotEmpty) {
      span.attributes['style'] = cssString;
    }
    span.append(dom.Text(text));
    return span;
}
