toIso8601StringWithOffset method
Returns an ISO-8601 full-precision extended format representation with an offset.
Implementation
String toIso8601StringWithOffset() {
var isoDate = toIso8601String();
if (isUtc) {
return isoDate;
} else {
// Because dart only knows the utc timezone and the local timezone,
// we convert the date to UTC. The toIso8601String will automatically append a 'Z',
// to signify the date string is a UTC date.
// We can't use something like timeZoneOffset, because this doesn't get populated
// for parsed dates (only locally created dates). And because we don't know if
// other clients like the backend are in the same local time,
// UTC is the only option.
return toUtc().toIso8601String();
}
