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() => [
      '$protocol',
      if (host.isNotEmpty) '-h $host',
      '--interface $interface',
      if (ttl != -1) '--ttl $ttl',
      if (connect) '-c',
      if (compress) '-z',
    ].join(' ');
