toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  final $buf = StringBuffer()..writeln('Level3LineItems(');
  if (discountAmount != null) {
    $buf
      ..writeln()
      ..write('  discount_amount: ')
      ..write(discountAmount)
      ..write(',');
  }
  $buf
    ..writeln()
    ..write('  product_code: ')
    ..write(productCode)
    ..write(',');
  $buf
    ..writeln()
    ..write('  product_description: ')
    ..write(productDescription)
    ..write(',');
  if (quantity != null) {
    $buf
      ..writeln()
      ..write('  quantity: ')
      ..write(quantity)
      ..write(',');
  }
  if (taxAmount != null) {
    $buf
      ..writeln()
      ..write('  tax_amount: ')
      ..write(taxAmount)
      ..write(',');
  }
  if (unitCost != null) {
    $buf
      ..writeln()
      ..write('  unit_cost: ')
      ..write(unitCost)
      ..write(',');
  }
  $buf.write(')');
  return $buf.toString();
}
