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 msg = message;
  if (address != null) msg = '$msg, address: $address';
  if (errorNumber != null) msg = '$msg, error: $errorNumber';
  return 'I2CException: $msg';
}
