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('InvoiceLineItemUpdateOptions(');
  if (amount != null) {
    $buf
      ..writeln()
      ..write('  amount: ')
      ..write(amount)
      ..write(',');
  }
  if (description != null) {
    $buf
      ..writeln()
      ..write('  description: ')
      ..write(description)
      ..write(',');
  }
  if (discountable != null) {
    $buf
      ..writeln()
      ..write('  discountable: ')
      ..write(discountable)
      ..write(',');
  }
  if (discounts != null) {
    $buf
      ..writeln()
      ..write('  discounts: ')
      ..write(discounts)
      ..write(',');
  }
  if (expand != null) {
