toString method
override
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() {
List<String> parts = [];
if (days > 0) parts.add('${days}d');
if (hours > 0) parts.add('${hours}h');
if (minutes > 0) parts.add('${minutes}m');
if (seconds > 0) parts.add('${seconds}s');
return parts.join(' ');
}
