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 yearSuffix = '-',
String monthSuffix = '-',
String daySuffix = ''}) {
String y = fourDigits(year);
String m = twoDigits(month);
String d = twoDigits(day);
return "$y$yearSuffix$m$monthSuffix$d$daySuffix";
}
