toString method
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() {
Map<String, dynamic> json = {};
json["authorizationNumber"] = authorizationNumber;
json["referenceNumber"] = referenceNumber;
json["status"] = status;
json["amount"] = amount;
json["currency"] = currency;
json["id"] = id;
json["message"] = message;
final value = jsonEncode(json);
return value;
}
