Chopper is an http client generator using source_gen and inspired from Retrofit.

Usage

Generator

Add the generator to your dev dependencies

dev_dependencies:
  build_runner: ^0.8.0
  chopper_generator: ^0.0.1

Define and Generate your API

// my_service.dart

import "dart:async";
import 'package:chopper/chopper.dart';

part "my_service.chopper.dart";

@ChopperApi("MyService", baseUrl: "/resources")
abstract class MyServiceDefinition {
  @Get(url: "/{id}")
  Future<Response> getResource(@Path() String id);

  @Get(url: "/", headers: const {"foo": "bar"})
  Future<Response<Map>> getMapResource(@Query() String id);
}

then run the generator

pub run build_runner build

#flutter
flutter packages pub run build_runner build

Use it

Create a Chopper client and inject your generated api.

final chopper = new ChopperClient(
    baseUrl: "http://localhost:8000",
    converter: const JsonConverter(),
    services: [
      // the generated service
      new MyService()
    ],
    interceptors: [
      new Headers(const {"Content-Type": "application/json"}),
    ]);

final myService = chopper.service(MyService) as MyService;

final response = await myService.getMapResource("1");
