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() {
  // TODO: implement toString
  return "pan: $pan, stan: $stan, rrn: $rrn, pinBlock: $pinBlock, iccData: $iccData,"
      " track2Data: $track2Data, postDataCode: $postDataCode, cardExpiryDate: $cardExpiryDate,"
      " acceptorCode: $acceptorCode, sequenceNumber: $sequenceNumber, serviceCode: $serviceCode,"
      " transactionCode: $transactionCode, terminalId: $terminalId, merchantName: $merchantName,"
      " customerName: $customerName, acquiringInstitutionalCode: $acquiringInstitutionalCode,"
      " amount: $amount, accountType: $accountType";
}
