Quick start

1. Dependencies

dependencies:
  net_retrofit_kit: ^0.1.0
  dio: ">=5.0.0"
dev_dependencies:
  build_runner: ^2.4.0

2. Config (once, e.g. in main())

NetRequest.options = const NetOptions(
  baseUrl: 'https://api.example.com',
  connectTimeout: Duration(seconds: 30),
  receiveTimeout: Duration(seconds: 30),
);

3. Define API

@NetApi()
abstract class UserApi {
  static UserApi get instance => UserApiImpl();
  @Get('/user/info')
  Future<UserModel?> getUserInfo();
  @Post('/login')
  Future<AuthModel?> login(@Body() LoginRequest body);
}

4. Generate
dart run build_runner build --delete-conflicting-outputs

5. Use
await UserApi.instance.getUserInfo();

Quick reference (annotations)

Annotation	Use
@NetApi()	On abstract class. Optional client: 'upload' for named client; else uses NetRequest.defaultKey.
@Get(path) @Post(path) @Put(path) @Delete(path)	HTTP method + path.
@Body()	Request body.
@Query()	Full query map. @QueryKey('name') = single query param.
@Path('id')	Path param for :id in path.
@Header('Authorization')	Request header.
@DataPath('key')	Parse from response.data['key'].
@Part('file')	Multipart part (with ContentType.formData).
@StreamResponse()	Return stream (SSE / line stream).
