One option to use your api key for tests without exposing it is implementing it as an environment variable and read it from there. Here is an example with github workflows:

Original Issue found on StackOverflow: https://stackoverflow.com/questions/76269906/open-route-service-flutter

Need to release a new version with functionality enabled, if it is a valid proposition.

OpenRouteService is a deprecated notation.
Please use openrouteservice (Start of record: Openrouteservice; abbr: ORS) instead.

I need to use another GeoJSON library to parse the response of openRouteService.geocodeAutoCompleteGet(), so I call FeatureCollection.fromJson(predictions.toJson()). where FeatureCollection is from another library.

However, the toJson() generated from this library is invalid GeoJSON, so it can't be parsed.

Thank you for great library.
We have installed openrouteservice in our server, so this means our api endpoint is not https://api.openrouteservice.org.
Can we change the baseUrl to our own subdomain?

GeoJsonFeatureCollection.toJson() does not work if the collection is empty from OpenRouteService.

import 'package:open_route_service/open_route_service.dart';

final openRouteService = OpenRouteService(apiKey: 'my_api_key');

void main() async {
  print((await openRouteService.geocodeAutoCompleteGet(text: 'skhfdkashfdkjashfdjs')).toJson());
}

Error:

Unhandled exception:

Optimization API

API Documentation: https://openrouteservice.org/dev/#/api-docs/optimization

The project structure is already set so just gotta fill in the dart files in the right places. :)

Matrix API

API Documentation: https://openrouteservice.org/dev/#/api-docs/v2/matrix/{profile}/post

The project structure is already set so just gotta fill in the dart files in the right places. :)

Apart from the usage instruction, there is currently nothing on how to setup the project and run the files in development mode.

This would be helpful for contributions.

Hello.
I'm getting the following error when doing a matrixPost with metrics different from the default ['duration']
TimeDistanceMatrix distanceMatrix = await client.matrixPost(locations: cities, metrics: ['distance'], units: 'm');
Do you have any idea why this happens? The request works OK in Postman, why is this happening in Flutter Dart? How can I fix it?
