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() {
String arg;
if (abbr != null) {
arg = '$_intent--$name, $abbr => $help';
} else {
arg = '$_intent--$name => $help';
}
if (expandHelp != null) {
arg += '\n$expandHelp';
}
return arg;
}
