toString method

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

String toString() {
  return "{\n" +
      "payload: $payload" +
      "\n" +
      "dismissInterval: ${dismissInterval.toString()}" +
      "\n" +
      "}";
}
