Overview
The dvhcvn package provides a comprehensive, up-to-date dataset of Vietnam's three-tier administrative divisions—provinces, districts, and communes—for use in Flutter applications. Designed for developers building location-based features, it enables accurate address selection and geolocation filtering. The data is regularly updated (last update: 01/03/2025) and supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux. It integrates seamlessly via a simple pub command and is ideal for forms, maps, or delivery systems requiring Vietnamese administrative structure.
