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() {
final buffer = StringBuffer();
if (offsetHour < 0) {
buffer.write('-');
}
final hour = offsetHour.abs();
if (hour < 10) {
buffer.write('0');
}
buffer.write(hour);
if (offsetMinute < 10) {
buffer.write('0');
}
buffer.write(offsetMinute);
return buffer.toString();
}
