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 msg = StringBuffer('WorkError [$_tag - $type] :$message');
if (origin != null) {
msg.writeln();
msg.writeln('$origin');
}
if (stack != null) {
msg.writeln();
msg.writeln('$stack');
}
return msg.toString();
}
