convertLines method

List<List<String>> convertLines(Iterable<String> lines, { bool? multiline, })

Parses given CSV lines

multiline can be used to control if a single row can span multiple lines

Implementation

List<List<String>> convertLines(Iterable<String> lines, {bool? multiline}) {
  final bool isMultiline = multiline ?? this.multiline;

  final List<List<String>> ret = [];

  String? previousLine;
  for (String line in lines) {
    if (previousLine == null) {
      final List<String>? row = parseRow(line, fs: fieldSep, ts: textSep);
      if (row != null) {
        ret.add(row);
      } else {
        if (!isMultiline) {
          throw Exception('Invalid row!');
        }
        previousLine = line;
      }
    } else {
      previousLine = previousLine + '\r\n' + line;
      final List<String>? row =
          parseRow(previousLine, fs: fieldSep, ts: textSep);
      if (row != null) {
        ret.add(row);
        previousLine = null;
      }
    }
  }

  return ret;
