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() {
  return '''
cardNumber: ${cardNumber},
cardholderName: ${cardholderName},
expiryDate: ${expiryDate},
cvv: ${cvv},
taxId: ${taxId},
brand: ${brand},
formVersion: ${formVersion},
cvvFieldVersion: ${cvvFieldVersion},
data: ${data},
isAmex: ${isAmex},
isEmpty: ${isEmpty}
  ''';
}
