    // if we've hit the end of a paragraph
    if (lastLine.length > 1 && line.isEmpty /*line == "\n"*/) {
      result.add(_prepString(curParagraph));
      curParagraph = "";

      // if we're still building the current paragraph
      /// replace as many first words of the paragraph as possible with the defined lorem ones, but only if this is the first paragraph
      if (startWithLorem && result.isEmpty && curParagraph.isEmpty) {
        List<String> firstWords = line.split(' ');
        firstWords.replaceRange(
          0,
          line.length < _lorem.length ? line.length : _lorem.length,
