Tanzania Geo Data

A comprehensive Flutter package for retrieving and searching Tanzanian geographic data, including Regions, Districts, Wards, and Streets. This package provides high-quality, verified data for all your location-based needs in Tanzania.

Features

• Hierarchical Data: Complete mapping from Regions -> Districts -> Wards -> Streets.
• Categorized Search: Search across all geographical levels simultaneously.
• Helper Methods: Easily retrieve wards by region or streets by district.
• Detailed Models: Every location level has its own dedicated model (Region, District, Ward, Street).
• Lightweight & Efficient: Static data loading for fast performance.

Getting Started

Add this to your pubspec.yaml:

dependencies:
  tanzania_geo_data: ^0.0.1

Then run:

flutter pub get

Usage

1. Initialize the Service

import 'package:tanzania_geo_data/tanzania_geo_data.dart';

final geoService = GeoService();

2. Get All Regions

List<Region> regions = geoService.getRegions();

3. Get Districts by Region

List<District> districts = geoService.getDistrictsByRegion('Dar es Salaam');

4. Get Wards by District

List<Ward> wards = geoService.getWardsByDistrict('Ilala District');

5. Get Streets by Ward

List<Street> streets = geoService.getStreetsByWard('Kariakoo');

6. Search for any Location

SearchResults results = geoService.search('Arusha');

print('Found ${results.regions.length} regions');
print('Found ${results.districts.length} districts');
print('Found ${results.wards.length} wards');
print('Found ${results.streets.length} streets');

7. Helper Methods

// Get all wards in a region directly
