toString method
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',
'-p $port',
if (sourceAddress.isNotEmpty) '--sourceAddress $sourceAddress',
if (timeout == -1) '-t infinite',
if (timeout != -1 && timeout != 0) '-t $timeout',
if (compress) '-z',
].join(' ');
