A simple and efficient Least Recently Used (LRU) cache implementation in Dart.

## Features

- Fixed-size cache with LRU eviction policy

- Generic key-value storage

- O(1) complexity for get, put, and remove operations

## Usage

```dart

import 'package:simple_lru_cache/simple_lru_cache.dart';

void main() {

  final cache = LRUCache(3);

  

  cache.put(1, 'one');

  cache.put(2, 'two');

  cache.put(3, 'three');

  

  print(cache.get(1));  // Outputs: one

  

  cache.put(4, 'four'); // This will evict the least recently used item (2)

  

  print(cache.containsKey(2)); // Outputs: false

}

```

## Installation

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

```yaml

dependencies:

  simple_lru_cache: ^0.2.1

```

Then run `dart pub get`.
