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 str = "ExternalRecord: ";
  str += basicInfoString;
  str += "type=$decodedType ";
  str += "payload=${(payload?.toHexString()) ?? '(null)'}";
  return str;
}
