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() {
  if (isOff) return "PowerOff";
  if (isLocked) return "Locked";
  if (isInit) return "Initializing";
  if (isReady) return "Ready";
  return "$init $powerOff $ready $unknown";
}
