Data API

A concrete implementation of the `DataClient` abstract class for interacting with data resource endpoints via HTTP.

This data_api package serves as a concrete implementation of the DataClient<T> abstract class within the Flutter News App Full Source Code Toolkit. It provides a robust and generic way to interact with RESTful data resource endpoints via HTTP, leveraging the http_client package for underlying communication and standardized error handling. This package ensures consistent data access across the Flutter mobile app, web dashboard, and Dart Frog backend API.

⭐ Feature Showcase: Seamless Data Endpoint Interaction

This package offers a comprehensive set of features for interacting with API data resources.

🧱 Core Functionality

🚀 Generic DataClient Implementation

• DataApi<T> Class: A concrete implementation of the DataClient<T> abstract class, enabling type-safe interactions with various data models.
• Unified API Endpoint Interaction: Configurable with a modelName (identifying the resource in the API) and fromJson/toJson functions for seamless serialization and deserialization of specific model types T.

🌐 Comprehensive Data Operations

• CRUD Operations: Implements create, read, update methods returning Future<SuccessApiResponse<T>>, and delete returning Future<void>.
• Advanced Querying: Provides a unified readAll method returning Future<SuccessApiResponse<PaginatedResponse<T>>>, supporting rich, document-style filtering (filter), multi-field sorting (sort), and cursor-based pagination (pagination).
• Counting and Aggregation: Includes count for efficient document counting and aggregate for executing complex data aggregation pipelines directly on the data source.

🛡️ Integrated Error Handling

• HttpException Propagation: Propagates standardized HttpException errors (e.g., NetworkException, BadRequestException, NotFoundException) from the underlying http_client package, ensuring consistent and predictable error management.

💉 Dependency Injection Ready

• HttpClient Dependency: Requires an instance of HttpClient (from the http_client package) via its constructor, promoting loose coupling and testability.

💡 Your Advantage: You get a meticulously designed, production-quality data API client that simplifies interactions with your backend, ensures type safety, provides robust error handling, and supports advanced querying capabilities. This package accelerates development by providing a solid foundation for data access.
