DateTime in UTC not converting to Local

Question

I'm receiving a DateTime response from API that's sets the timezone to UTC.

But when I try to convert the received data using toLocal() it doesn't convert.

my local time is HKT

here's my code.

    //TIME DIFFERENCE   getNotificationDate(DateTime date) {     date = date.toUtc();     final convertedDate = date.toLocal();      final dateNow = DateTime.now();     print('TIMENOW: ' + dateNow.toString());     print('TIMENOTIFC: ' + convertedDate.toString());     final difference = dateNow.difference(convertedDate);     print('DIFFERENCE: ' + difference.toString());     return getDurationFormat(difference);   } 

EDIT:

date is the DateTime I'm receiving from the API. which is in UTC timezone.

I used print('TIMEZONENAME: ' + date.timeZoneName; and it automatically sets the timezone to HKT. that's why it does nothing when I try to use date.toLocal()

Flutter gave us the easiest way to convert it. You just need to pass utc: true while parsing your date.

var dateTime = DateFormat("yyyy-MM-dd HH:mm:ss").parse(dateUtc, true); var dateLocal = dateTime.toLocal(); 

Input:

Assume my TimeZone : +05:30

UTC Date -> 2020-02-12 23:57:02.000

Output:

Local Date -> 2020-02-12 18:27:02.019660
