Dioxide

Dioxide is a type conversion dio client generator.

Using

Add dependencies

dependencies:
  dioxide: ^lastVersion

dev_dependencies:
  build_runner: ^2.2.0
  dioxide_generator: ^lastVersion

Define and Generate your API

import 'package:json_annotation/json_annotation.dart';
import 'package:dio/dio.dart';
import 'package:dioxide/dioxide.dart';

part 'example.g.dart';

@RestApi(baseUrl: "http://localhost:8080/api/Task")
abstract class RestClient {
  factory RestClient(Dio dio, {String baseUrl}) = _RestClient;

  @GetRequest()
  Future<List<Task>> getTasks();
}

@JsonSerializable()
class Task {
  String? id;
  String? name;
  String? avatar;
  String? createdAt;

  Task({this.id, this.name, this.avatar, this.createdAt});

  factory Task.fromJson(Map<String, dynamic> json) => _$TaskFromJson(json);

  Map<String, dynamic> toJson() => _$TaskToJson(this);
}

then run the generator

# dart
pub run build_runner build

# flutter
flutter pub run build_runner build

Type Conversion

Before you use the type conversion, please make sure that a factory Task.fromJson(Map<String, dynamic> json) must be provided for each model class. json_serializable is the recommanded to be used as the serialization tool.

@GetRequest("/tasks") Future<List<Task>> getTasks();

@JsonSerializable()
class Task {
  String name;
  Task({this.name});
  factory Task.fromJson(Map<String, dynamic> json) => _$TaskFromJson(json);
}

HTTP Methods

The HTTP methods in the below sample are supported.

@GetRequest("/tasks/{id}")
Future<Task> getTask(@Path("id") String id);

@GetRequest('/demo')
Future<String> queries(@Queries() Map<String, dynamic> queries);

@GetRequest("/search")
Future<String> namedExample(
    @Query("name") String name,
    @Query("tag") String tag,
);

@PatchRequest("/tasks/{id}")
Future<Task> updateTaskPart(@Path() String id, @Body() Map<String, dynamic> map);

@PutRequest("/tasks/{id}")
Future<Task> updateTask(@Path() String id, @Body() Task task);

@DeleteRequest("/tasks/{id}")
Future<void> deleteTask(@Path() String id);

@PostRequest("/tasks")
Future<Task> createTask(@Body() Task task);

@PostRequest("/post")
Future<void> createNewTaskFromFile(@Part() File file);

@PostRequest("/post")
@FormUrlEncoded()
Future<String> postUrlEncodedFormData(@Field() String hello);

Get original HTTP response

@GetRequest("/tasks/{id}")
Future<HttpResponse<Task>> getTask(@Path("id") String id);

@GetRequest("/tasks")
Future<HttpResponse<List<Task>>> getTasks();

Get dio Response

@GetRequest("/file/{fileId}")
@DioResponseType(ResponseType.stream)
Future<Response<ResponseBody>> getTask(@Path("fileId") String id);

HTTP Header

• Add a HTTP header from the parameter of the method

  @GetRequest("/tasks")
  Future<Task> getTasks(@Header("Content-Type") String contentType );
  

• Add static HTTP headers

  @GetRequest("/tasks")
  @Headers(<String, dynamic>{
  	"Content-Type" : "application/json",
  	"Custom-Header" : "Your header"
  })
  Future<Task> getTasks();
  

Multiple endpoints support

If you want to use multiple endpoints to your RestClient, you should pass your base url when you initiate RestClient. Any value defined in RestApi will be ignored.

@RestApi(baseUrl: "this url will be ignored if baseUrl is passed")
abstract class RestClient {
  factory RestClient(Dio dio, {String baseUrl}) = _RestClient;
}

final client = RestClient(dio, baseUrl: "your base url");

If you want to use the base url from dio.option.baseUrl, which has lowest priority, please don't pass any parameter to RestApi annotation and RestClient's structure method.

Set request timeout

@RestApi(baseUrl: 'http://localhost:8080/api/Report')
@RequestTimeout(connectTimeout: 5000, sendTimeout: 5000, receiveTimeout: 5000)
abstract class ReportClient {
  @GetRequest("/generate")
  @RequestTimeout(sendTimeout: 15000, receiveTimeout: 30000)
  @DioResponseType(ResponseType.stream)
  Future<Response<ResponseBody>> getTask(@Queries() Map<String, dynamic> queries);
}
