+# flutter_policy_engine_example
+
+A comprehensive example demonstrating how to use the `flutter_policy_engine` library for implementing Attribute-Based Access Control (ABAC) and Role-Based Access Control (RBAC) in Flutter applications.
+
+## Overview
+
+The `flutter_policy_engine` library provides a lightweight, extensible policy engine for Flutter applications. It allows you to define, manage, and evaluate access control rules declaratively using ABAC or RBAC models.
+
+## Features Demonstrated
+
+- **Attribute-Based Access Control (ABAC)**: Define policies based on user attributes, resource properties, and environmental factors
+- **Role-Based Access Control (RBAC)**: Implement role-based permissions with hierarchical role structures
+- **Declarative Rule Definitions**: Define policies using a clean, readable syntax
+- **Extensible Design**: Easily extend the engine with custom evaluators and conditions
+- **Flutter Integration**: Seamless integration with Flutter widgets and state management
+
+## Installation
+
+Add the `flutter_policy_engine` dependency to your `pubspec.yaml`:
+
+```yaml
+dependencies:
+  flutter_policy_engine: ^0.0.1
+```
+
+Then run:
+
+```bash
+flutter pub get
+```
+
+## Basic Usage
+
+### 1. Import the Library
+
+```dart
+import 'package:flutter_policy_engine/flutter_policy_engine.dart';
+```
