DataFrame sort(
  1. Iterable<Expr> by, {
  2. Object descending = false,
  3. Object nullsLast = false,
  4. bool maintainOrder = false,
})

Implementation

DataFrame sort(
  Iterable<Expr> by, {
  Object descending = false,
  Object nullsLast = false,
  bool maintainOrder = false,
}) {
  final values = List<Expr>.unmodifiable(by);
  return _frameExpressions(
    'frameSort',
    'by',
    values,
    allowEmpty: false,
    fields: {
      'descending': _broadcast(descending, values.length, 'descending'),
      'nullsLast': _broadcast(nullsLast, values.length, 'nullsLast'),
      'maintainOrder': maintainOrder,
    },
  );
}
