timezone_provider

A Flutter plugin to get the device's IANA timezone name.

Motivation

Dart's DateTime.now().timeZoneName returns timezone abbreviations like "JST" or "EST", not IANA timezone identifiers. However, IANA timezone names (e.g., Asia/Tokyo, America/New_York) are often required for:

• Server-side analytics and logging
• Database storage with proper timezone handling
• Scheduling and calendar applications
• Any system that needs unambiguous timezone identification

Why not other packages?

• flutter_native_timezone: A well-designed package, but it has not been updated for a long time and has unresolved issues.
• timezone: Provides timezone database and calculations, but cannot retrieve the device's local timezone identifier.

This plugin provides a simple, maintained solution for accessing the device's IANA timezone identifier from native platform APIs.

Installation

dependencies:
  timezone_provider: ^0.0.1

Usage

import 'package:timezone_provider/timezone_provider.dart';

final provider = TimezoneProvider();
final timezone = await provider.getTimezone();
print(timezone); // "Asia/Tokyo"
