my_timezone returns the device's local IANA time zone identifier and the available identifiers on Android, iOS, macOS, and web.

Features

• Get the local timezone from the native layer.
• Get the list of available timezones.
• Uses one stable MethodChannel contract across Android, iOS, macOS, and web.
• Requires Flutter 3.47.1 or newer and Dart 3.13.1 or newer.

Platform requirements

• Android API 24 or newer.
• iOS 15.0 or newer.
• macOS 12.0 or newer.
• A modern browser with Intl.DateTimeFormat support.

Installation

Add the following to your pubspec.yaml:

my_timezone: ^0.0.4

Then run:

flutter pub get

Basic usage

import 'package:my_timezone/my_timezone.dart';

final String localTimezone = await MyTimezone.getLocalTimezone();
final List<String> availableTimezones =
    await MyTimezone.getAvailableTimezones();

On web, browsers expose the local identifier but not the complete IANA time zone database. getAvailableTimezones() therefore returns a one-item list containing the local identifier.

Example in a widget

class _MyAppState extends State<MyApp> {
  String? _timezone;

  @override
  void initState() {
    super.initState();
    _loadTimezone();
  }

  Future<void> _loadTimezone() async {
    final timezone = await MyTimezone.getLocalTimezone();
    if (!mounted) return;
    setState(() => _timezone = timezone);
  }
}
