dio_api_kit #

A lightweight, flexible, and backend-agnostic API layer built on top of Dio.

dio_api_kit provides:

• Centralized Dio initialization
• Clean API service abstraction
• Generic API response model
• Configurable success resolver
• Unified API error handling
• Backend-independent parsing

✨ Why dio_api_kit? #

Most APIs return responses in different formats:

• status: true
• status: 200
• status: "success"
• success: 1

Instead of hardcoding response assumptions, dio_api_kit allows you to define how success is determined — making it completely backend-agnostic.

📦 Installation #

Add to your pubspec.yaml:

dependencies:
  dio_api_kit: ^1.*.*

🚀 Getting Started #

1️⃣ Initialize at App Startup

Call this once (e.g., in main()):

DioApiKit.initialize(
  baseUrl: "https://api.example.com",
  apiConfig: ApiConfig(
    isSuccess: (status) => status == true || status == 200,
  ),
  interceptors: [
    LogInterceptor(responseBody: true),
  ],
);

2️⃣ Make an API Call

Example repository usage:

final user = await APIWrapper.handleApiCall<User>(
  request: () async {
    final response = await DioApiKit.api.get<Map<String, dynamic>>(
      path: '/user',
    );

    return ApiResponse<User>.fromJson(
      response.data!,
      statusExtractor: (json) => json['status'],
      messageExtractor: (json) => json['message'],
      dataParser: (data) => User.fromJson(data),
    );
  },
  onError: (message) {
    print(message);
  },
);

🏗 Architecture Overview #

1️⃣ DioApiKit

• Initializes Dio
• Injects interceptors
• Sets base options
• Initializes APIWrapper

2️⃣ APIService

Thin wrapper around Dio.

Provides:

• get
• post
• put
• delete
• patch

No business logic included.

3️⃣ ApiResponse

Generic, backend-agnostic response model.

You provide:

• statusExtractor
• messageExtractor
• dataParser

This avoids coupling to any backend format.

4️⃣ APIWrapper

Handles:

• Success validation
• Error propagation
• Typed data return
• Boilerplate removal

🎯 Design Goals

• Backend-agnostic
• Strongly typed
• Testable
• Clean architecture friendly
• Minimal boilerplate
• Easily extendable

🧩 Example Success Resolver

ApiConfig(
  isSuccess: (status) {
    if (status is bool) return status;
    if (status is int) return status >= 200 && status < 300;
    if (status is String) return status.toLowerCase() == "success";
    return false;
  },
);

🔐 Interceptors Support

You can inject any Dio interceptors:

interceptors: [
  LogInterceptor(),
  YourAuthInterceptor(),
]

🧪 Testing

Because APIService is injected, you can easily:

• Mock Dio
• Mock ApiResponse
• Test repositories independently
