final Workbook workbook = Workbook();
final Worksheet sheet = workbook.worksheets[0];
final Style style = workbook.styles.add('style');
// set back color.
style.backColor = '#37D8E9';
final Range range1 = sheet.getRangeByIndex(3, 4);
range1.number = 10;
range1.cellStyle = style;
final List<int> bytes = workbook.saveAsStream();
File('CellStyle.xlsx').writeAsBytes(bytes);
workbook.dispose();

Implementation

@override
String get backColor {
  String backColorStyle = '';
  bool first = true;

  final int last = _arrRanges.length;
  for (int index = 0; index < last; index++) {
    final Range range = _arrRanges[index];

    if (first) {
      backColorStyle = range.cellStyle.backColor;
      first = false;
    } else if (range.cellStyle.backColor != backColorStyle) {
      return 'none';
    }
  }
  return backColorStyle;
}
