String emojify(String text, {String Function(String)? fnFormat}) {
  Iterable<Match> matches = REGEX_NAME.allMatches(text);
  if (matches.isNotEmpty) {
    var result = text;
    for (Match m in matches) {
      var _e = EmojiUtil.stripColons(m.group(0));
      if (_e == null || m.group(0) == null) continue;
      if (hasName(_e)) {
        var pattern = RegExp.escape(m.group(0)!);
        var formattedCode = get(_e).code;
        if (fnFormat != null) {
          formattedCode = fnFormat(formattedCode);
        }
        result =
            result.replaceAll(RegExp(pattern, unicode: true), formattedCode);
      }
    }
    return result;
  }
  return text;
