Auth In-Memory

An in-memory implementation of the `AuthClient` interface for the Flutter News App Toolkit.

This auth_inmemory package provides an in-memory implementation of the AuthClient interface within the Flutter News App Full Source Code Toolkit. It offers a mock authentication client that operates entirely on in-memory data, making it suitable for demonstration purposes, local development, and testing without requiring a live backend. This package simulates various authentication flows, ensuring consistent behavior and robust error handling based on the auth_client contract.

⭐ Feature Showcase: Simplified Authentication Testing & Development

This package offers a comprehensive set of features for managing authentication operations in a simulated environment.

🧱 Core Functionality

🚀 AuthClient Implementation

• AuthInmemory Class: A concrete in-memory implementation of the AuthClient interface, providing a standardized way to simulate authentication.
• Simulated Authentication Flows: Implements requestSignInCode, verifySignInCode, signInAnonymously, and signOut to simulate various authentication processes.
• Reactive State Changes: Provides authStateChanges (a stream that emits the current authenticated User or null on state changes) and getCurrentUser to retrieve the current user.

🌐 Debugging & Validation

• Privileged Flow Simulation: Supports an isDashboardLogin flag in requestSignInCode and verifySignInCode to simulate privileged flows, allowing testing of admin-specific authentication logic (e.g., only [email protected] is allowed).
• Token Retrieval: Includes a currentToken getter to retrieve the simulated authentication token for inspection during development.

🛡️ Standardized Error Handling

• HttpException Propagation: Throws standard HttpException subtypes (e.g., UnauthorizedException, NotFoundException, AuthenticationException, InvalidInputException) from core on simulated failures, ensuring consistent error handling in a testing context.

💡 Your Advantage: This package provides a reliable, in-memory authentication client that simplifies testing and development of authentication-related features. It eliminates the need for external backend dependencies during development, offering immediate feedback and consistent behavior for your authentication logic, especially for complex scenarios like privileged logins.
