Get Flutter current time zone

Any app you implement in Flutter, that has server times – most probably will also need to get the current time zone on the user device.

---

1. Get the device’s local time zone name

Example: America/New_York, Asia/Kolkata

Using flutter_native_timezone

This gives the actual system time zone, not just an offset.

Add dependency

dependencies:
  flutter_native_timezone: ^2.0.0

Code

import 'package:flutter_native_timezone/flutter_native_timezone.dart';

Future<void> getTimeZone() async {
  String timeZone = await FlutterNativeTimezone.getLocalTimezone();
  print(timeZone);
}

✅ Best when you need accurate timezone IDs
✅ Works on Android & iOS

---

2. Get the UTC offset (no package needed)

Example: +05:30, -04:00

DateTime now = DateTime.now();
Duration offset = now.timeZoneOffset;

print(offset); // e.g. 5:30:00

To format it:

String formatOffset(Duration offset) {
  final hours = offset.inHours;
  final minutes = offset.inMinutes.remainder(60);
  return '${hours >= 0 ? '+' : '-'}'
         '${hours.abs().toString().padLeft(2, '0')}:'
         '${minutes.abs().toString().padLeft(2, '0')}';
}

print(formatOffset(now.timeZoneOffset)); // +05:30

---

3. Get the time zone abbreviation

Example: IST, EST, PDT

DateTime now = DateTime.now();
print(now.timeZoneName);

⚠️ This is not reliable across platforms and locales.

4. Full timezone support (convert between zones)

If you need to convert times across time zones:

Add dependencies

dependencies:
  timezone: ^0.11.1
  flutter_native_timezone: ^2.0.0

Initialize

import 'package:timezone/data/latest.dart' as tz;
import 'package:timezone/timezone.dart' as tz;

Future<void> initTimeZones() async {
  tz.initializeTimeZones();
  final String localTimeZone =
      await FlutterNativeTimezone.getLocalTimezone();
  tz.setLocalLocation(tz.getLocation(localTimeZone));
}
