Email Client

An abstract interface for sending emails within the Flutter News App Toolkit.

This email_client package defines the abstract interface (EmailClient) for sending emails within the Flutter News App Full Source Code Toolkit. It establishes a clear contract that concrete implementations (e.g., using SMTP, AWS SES, SendGrid) should adhere to. This approach decouples application logic from specific email service providers and email content/styling, which can be managed directly within your chosen email service. This package is crucial for backend services (like a Dart Frog API) that require robust and flexible email dispatch capabilities.

⭐ Feature Showcase: Flexible & Provider-Agnostic Email Dispatch

This package offers a comprehensive set of features for managing email sending operations.

🧱 Core Functionality

🚀 Abstract EmailClient Interface

• EmailClient Abstract Class: Defines a generic, provider-agnostic interface for sending transactional emails. This decouples application logic from specific email service providers.
• sendTransactionalEmail Method: Provides a method for sending emails using pre-defined templates, requiring senderEmail, recipientEmail, subject, templateId, and templateData. This allows email content and styling to be managed directly within the email service provider.

🛡️ Standardized Error Handling

• HttpException Propagation: Implementations are expected to handle underlying service errors and map them to standard HttpException subtypes (from core), ensuring consistent error management across the application layers.

💉 Implementation Agnostic

• Interchangeable Implementations: Designed to be implemented by various email service providers (e.g., SendGrid, AWS SES, local SMTP), allowing developers to swap email solutions without altering core application logic.

💡 Your Advantage: This package provides a clear, abstract interface for email sending, decoupling your application from specific email service providers. This design promotes flexibility, testability, and maintainability, allowing you to easily integrate and swap email solutions as needed.
