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() {
var message = '';
if (code != null) {
message += 'Code: $code ';
}
if (title != null) {
message += 'Title: $title ';
}
if (description != null) {
message += 'Description: $description ';
}
return message;
}
