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() {
String result = 'PaymentException: $message';
if (statusCode != null) {
result += ' (Status Code: $statusCode)';
}
if (errorCode != null) {
result += ' [Error Code: $errorCode]';
}
if (responseBody != null) {
result += '\nResponse: $responseBody';
}
if (cause != null) {
result += '\nCause: $cause';
}
return result;
}
