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 (deviceId != null) {
    return "Could not connect to device ($deviceId) for unknown reason";
  }
  if (uuid != null) {
    return "Could not communicate with uuid ($uuid) for unknown reason";
  }
  return "A network error (for Bluetooth) has occurred";
}
