Implementation
Future<List<Cell>?> lastRow({
int fromColumn = 1,
int length = -1,
bool inRange = false,
}) async {
if (inRange) {
final rows = await _ws.values.allRows(
fromColumn: fromColumn,
length: length,
);
if (rows.isEmpty) return null;
return _wrapRow(rows.last, rows.length, fromColumn);
} else {
checkIndex('fromColumn', fromColumn);
final rows = await _ws.values.allRows();
if (rows.isEmpty) return null;
final list = extractSublist(
rows.last,
from: fromColumn - 1,
length: length,
);
return _wrapRow(list, rows.length, fromColumn);
}
