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 result = StringBuffer();
ResultNode? previous;
for (ResultNode current in list) {
if (previous != null) {
result.write(',');
}
result.write(current.toString());
previous = current;
}
return result.toString();
}
