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 sb = StringBuffer();
sb.writeln('Payload: Unsubscription [{${subscriptions.length}}]');
for (final subscription in subscriptions) {
sb.writeln('{{ Topic={$subscription}}');
}
return sb.toString();
}
