optimization-flutter-sdk

The optimization-flutter-sdk is a powerful tool that helps businesses optimize their delivery routes to maximize efficiency, save time, and reduce costs. It is designed to solve both Single and/or Multi Vehicle Routing Problem (VRP), which is a classic optimization problem in operations research that involves finding the optimal set of routes for a fleet of vehicles to visit a set of locations while satisfying various constraints such as time windows, capacity, and vehicle availability.

Initialization

Before using the SDK, you need to initialize it with your NextBillion access key.

import 'package:nextbillion_optimization/nextbillion_optimization.dart';

void main() {
  NextBillionOptimization.initialize('YOUR_ACCESS_KEY');
}

Usage

Optimize Route with Multiple Waypoints

To optimize a route with multiple waypoints, use the optimizeRouteWithMultiWaypoints method.

import 'package:nextbillion_optimization/nextbillion_optimization.dart';

OptimizeRequestParams optimizeRequest = OptimizeRequestParams(
  // Fill in with your request parameters
);

Future<void> getOptimizedRoute() async {
  OptimizeRouteResultResponse? response = await NextBillionOptimization.optimizeRouteWithMultiWaypoints(optimizeRequest);
  if (response != null) {
    print(response.result);
  } else {
    print('Failed to get optimized route');
  }
}

Optimize Route with Request Body

To optimize a route using a custom request body, use the optimizeRouteWithRequestBody method.

import 'package:nextbillion_optimization/nextbillion_optimization.dart';

Map<String, dynamic> requestBody = {
  // Fill in with your request body
};

Future<void> getOptimizedRoute() async {
  OptimizeRouteResultResponse? response = await NextBillionOptimization.optimizeRouteWithRequestBody(requestBody);
  if (response != null) {
    print(response.result);
  } else {
    print('Failed to get optimized route');
  }
}

Error Handling

The SDK handles errors using DioException. Ensure to catch and handle errors appropriately in your application.

try {
  OptimizeRouteResultResponse? response = await NextBillionOptimization.optimizeRouteWithMultiWaypoints(optimizeRequest);
  // Process response
} catch (e) {
  if (e is DioException) {
    print('Dio error: ${e.response?.data}');
  } else {
    print('Error: $e');
  }
}
