## Installation

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

```yaml
dependencies:
  platform_contracts: ^1.0.0
```

This package requires Dart SDK version 3.0.0 or later.

Dependencies:
- meta: ^1.9.0
- dsr_container: ^1.0.0
- dsr_simple_cache: ^1.0.0

Then run:

```
dart pub get
```

## Features

The Platform Contracts package includes contracts for various components of a web application framework, including:

- Authentication and Authorization
- Broadcasting
- Caching
- Configuration
- Console Applications
- Container (Dependency Injection)
- Database and ORM
- Encryption
- Event Handling
- Filesystem
- HTTP Handling
- Mailing
- Notifications
- Pagination
- Queues
- Redis Integration
- Routing
- Session Management
- Validation
- View Rendering

## Usage

Import the package in your Dart code:

```dart
import 'package:platform_contracts/contracts.dart';
```

Then implement the desired interfaces or extend the abstract classes to create your own implementations that adhere to the defined contracts.

## Package Structure

The package is organized into several subdirectories under `lib/src/`, each focusing on a specific area of functionality:

- `auth/`: Authentication and authorization contracts
- `broadcasting/`: Contracts for event broadcasting
- `cache/`: Caching system contracts
- `config/`: Configuration management contracts
- `console/`: Console application contracts
- `container/`: Dependency injection container contracts
- `database/`: Database and ORM contracts
- `encryption/`: Encryption service contracts
- `events/`: Event dispatching contracts
- `filesystem/`: Filesystem interaction contracts
- `http/`: HTTP request and response contracts
- `mail/`: Mailing service contracts
- `notifications/`: Notification system contracts
- `pagination/`: Pagination contracts
- `queue/`: Queue system contracts
- `redis/`: Redis integration contracts
- `routing/`: Routing system contracts
- `session/`: Session management contracts
- `validation/`: Validation system contracts
- `view/`: View rendering contracts

Each subdirectory contains interfaces and abstract classes that define the contracts for their respective areas.

## Examples

Here are a few examples of how to use the contracts in this package:

### Implementing an Authenticatable User

```dart
import 'package:platform_contracts/contracts.dart';

class User implements Authenticatable {
  @override
  String getAuthIdentifierName() => 'id';

  @override
  String getAuthIdentifier() => '12345';

  @override
  String getAuthPassword() => 'hashed_password';

  // Implement other methods...
}
```

### Creating a Custom Cache Store

```dart
import 'package:platform_contracts/contracts.dart';

class CustomCacheStore implements Store {
  @override
  Future<dynamic> get(String key) {
    // Implementation
  }

  @override
  Future<bool> put(String key, dynamic value, Duration? ttl) {
    // Implementation
  }

  // Implement other methods...
}
```
