Timezone package makes life a bit easier to deal with those pain in the neck issues related to timezone. However, I had a bunch of issues using that package, so documenting them here for someone else to save some time.
- Take a look at Udit's post. That helped me a lot.
- Take a look at resources at [IANA].(https://www.iana.org/time-zones)
- Download the timezone database.
git clone https://github.com/srawlins/timezone.git cd timezone flutter pub get flutter pub run tool/get -s 2020a cd lib/data - Add it to your codebase.
cp lib/data/2020a* <project_dir>/assets/timezone/ cd <project_dir> git add->commit->push Also, add it to your pubspec file under assets with the path you used above.
- Use it in your code.
Future<void> initTimezones() async { // get device timezone String dtz = await FlutterNativeTimezone.getLocalTimezone(); // Load timezone data var byteData = await rootBundle.load('assets/timezone/2020a.tzf'); tz.initializeDatabase(byteData.buffer.asUint8List()); tz.initializeTimeZones(); // set the local location. tz.setLocalLocation(tz.getLocation(dtz)); // Iterate and use through the list of timezones. _locations = tz.timeZoneDatabase.locations; _locations.values.forEach((element) { print(element.name); print(element.currentTimeZone.abbr); print(element.currentTimeZone.offset); print(element.currentTimeZone.isDst); print(element.zones.length); }); } - For timezone conversion, readme on the package provides great examples, so I will skip repetition.
Hope this helps someone.

Hey Shailesh, i have been trying to implemet timezone specific time in the app,
Setup is done now,
I want to know how to add a default timezone for whole app.
I dont want to everytime convert the time.
Is there any way so that i set the time to specific timezone by default?
ad when i do DateTime.now() it gives only that time?
