toMap method Null safety
- {int? nodeId}
Converts this event to a Map that can be encoded with StandardMessageCodec.
nodeId
is the unique identifier of the semantics node associated with
the event, or null if the event is not associated with a semantics node.
Implementation
Map<String, dynamic> toMap({ int? nodeId }) {
final Map<String, dynamic> event = <String, dynamic>{
'type': type,
'data': getDataMap(),
};
if (nodeId != null) {
event['nodeId'] = nodeId;
}
return event;
}
