toString method

@override String toString()

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() {
  var ret = new Map();
  ret['value'] = value.toString();
  ret['timestamp'] = timestamp;
  ret['data'] = data;
  return const JsonEncoder().convert(ret);
}
