Networking Layer #

A robust, SOLID-compliant networking package for Flutter using Dio.

Features #

• Decoupled Architecture: Independent of app-specific logic using DioConfig.
• SOLID Principles: Clean separation of concerns.
• Interceptors: Built-in support for Logging, Auth, Caching, and Retries.
• GraphQL & REST: Unified ApiClient mixin for both.
• Error Handling: Standardized HelperResponse with functional error handling (Either).

Installation #

Add this to your package's pubspec.yaml file:

dependencies:
  networking_layer:
    path: ./packages/networking_layer # If local
    # OR
    # git:
    #   url: https://github.com/your_username/networking_layer.git

Usage #

1. Initialize DioServices in your main.dart:

void main() {
  DioServices.instance.init(
    DioConfig(
      baseUrl: 'https://api.example.com',
      getToken: () => 'your_token',
      translate: (key) => key, // Your cleanup logic
    ),
  );
  runApp(MyApp());
}

2. Create a Repository using ApiClient:

class UserRepository with ApiClient {
  Future<Either<HelperResponse, User>> getUser(String id) async {
    return await get<User>(
      '/users/$id',
      fromJson: (json) => User.fromJson(json),
    );
  }
}
