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() {
  final buff = StringBuffer('PingResponse(seq:$seq');
  if (ip != null) buff.write(', ip:$ip');
  if (ttl != null) buff.write(', ttl:$ttl');
  if (time != null) {
    final ms = time!.inMicroseconds / Duration.millisecondsPerSecond;
    buff.write(', time:$ms ms');
  }
  buff.write(')');
  return buff.toString();
}
