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 outcome = isInProgress
      ? 'IN_PROGRESS'
      : isNoStatement
          ? 'NO_STATEMENT($responseCode)'
          : isTechnicalError
              ? 'TECHNICAL_ERROR($responseCode)'
              : isHostUncertain
                  ? 'HOST_UNCERTAIN($responseCode)'
                  : isApproved
                      ? 'APPROVED'
                      : isConclusive
                          ? 'DECLINED($responseCode)'
                          : 'UNKNOWN_CODE($responseCode)';
  return 'TransactionResponse($outcome, type=$transactionType, '
      'amount=$amount $currency, brand=$brand, card=$cardNumber, '
      'approval=$approvalCode, tx=$transactionId, text=$responseText)';
}
