Simple LRU Cache

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

void main() {
  final cache = LRUCache<int, String>(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
}
