*.chopper.dart not found ?

If you have this error, you probably forgot to run the build package. To do that, simply run the following command in your shell.

pub run build_runner build

It will generate the code that actually do the HTTP request (YOUR_FILE.chopper.dart). If you wish to update the code automatically when you change your definition run the watch command.

pub run build_runner watch

How to increase timeout ?

Connection timeout is very limited for now due to http package (see: dart-lang/http#21)

But if you are on VM or Flutter you can set the connectionTimeout you want

import 'package:http/io_client.dart' as http;
import 'dart:io';

final chopper = ChopperClient(
    client: http.IOClient(
      HttpClient()..connectionTimeout = const Duration(seconds: 60),
    ),
  );

Add query parameter to all requests

Possible using an interceptor.

final chopper = ChopperClient(
    interceptors: [_addQuery],
);

Request _addQuery(Request req) {
  final params = Map<String, dynamic>.from(req.parameters);
  params['key'] = '123';

  return req.replace(parameters: params);
}

Use Https certificate

Chopper is built on top of http package and you can override the inner http client.

import 'dart:io';
import 'package:http/io_client.dart' as http;

final ioc = new HttpClient();
ioc.badCertificateCallback = (X509Certificate cert, String host, int port) 
  => true;

final chopper = ChopperClient(
  client: http.IOClient(ioc),
);
