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() {
final parts = <String>['VinculumException: $message'];
if (statusCode != null) parts.add('status: $statusCode');
if (code != null) parts.add('code: $code');
if (requestId != null) parts.add('requestId: $requestId');
return parts.join(' | ');
}
