nb optimization flutter

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');
}
