Nominatim Flutter Plugin with Isolate Loading & Hive Caching

The Nominatim Flutter Plugin offers seamless interaction with the Nominatim service, allowing for reverse geocoding and place searching in your Flutter applications. Notably, it supports asynchronous data loading via a dedicated isolate and provides efficient caching using Hive, enhanced with DioCache customization.

Features

• Reverse Geocoding & Place Searching: Directly integrate with Nominatim.
• Asynchronous Isolate Loading: Load data in a separate thread, ensuring your UI remains smooth.
• Hive Caching: Speed up data retrieval with efficient caching.
• DioCache Customization: Take control of caching behavior by configuring DioCache settings.

Usage

To use the Nominatim Flutter Plugin, follow these steps:

1. Installation: Add the package to your pubspec.yaml file and run flutter pub get to install it.

   dependencies:
     nominatim_flutter: ^0.0.2 # Replace with the latest version
   

2. Import Classes: Import the necessary classes in your Dart code.

   import 'package:nominatim_flutter/nominatim_flutter.dart';
   

3. Configuration (Optional): Before you start making requests, you can optionally set up caching preferences using DioCache.

   NominatimFlutter.instance.configureDioCache(
     useCacheInterceptor: true, 
     maxStale: Duration(days: 7),
   );
   

   This step allows you to determine whether the cache interceptor is used and to set the maximum staleness of the cache.

4. Reverse Geocoding: Retrieve address information from latitude and longitude coordinates.

   final reverseRequest = ReverseRequest(
     lat: 10.7950,
     lon: 106.7218,
     addressDetails: true,
     extraTags: true,
     nameDetails: true,
   );
   final reverseResult = await NominatimFlutter.instance.reverse(
     reverseRequest: reverseRequest,
   );
   print(reverseResult);
   

5. Search for Places: Search for places based on query and location.

   final searchRequest = SearchRequest(
     query: 'Landmark 81',
     limit: 3,
     addressDetails: true,
     extraTags: true,
     nameDetails: true,
   );
   final searchResult = await NominatimFlutter.instance.search(
     searchRequest: searchRequest,
   );
   for (var result in searchResult) {
     print(result);
   }
