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('IssuingTransactionNetworkData(');
  if (authorizationCode != null) {
    $buf
      ..writeln()
      ..write('  authorization_code: ')
      ..write(authorizationCode)
      ..write(',');
  }
  if (processingDate != null) {
    $buf
      ..writeln()
      ..write('  processing_date: ')
      ..write(processingDate)
      ..write(',');
  }
  if (transactionId != null) {
    $buf
      ..writeln()
      ..write('  transaction_id: ')
      ..write(transactionId)
      ..write(',');
  }
  $buf.write(')');
  return $buf.toString();
}
