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() {
return '''
{
"id": "$id",
"type": "$type",
"name": "$name",
"topic": "$topic",
"x": 600,
"y": 300,
"qos": "$qos",
"retain": "",
"broker": "$brokerNodeId",
"wires": ${fixWiresForNodeRed()}
}''';
}
