Flyweight Factory (CharacterFactory):?

Short answer: The CharacterFactory is responsible for managing the flyweights. It keeps track of the existing character objects and ensures that no duplicate instances of the same character are created. If a character already exists in the dictionary, it is reused. Otherwise, a new Character object is created and stored for future use. public class CharacterFactory

Example code

{
private readonly Dictionary<char, Character> _characters = new
Dictionary<char, Character>();
public Character GetCharacter(char symbol)
{
if (!_characters.ContainsKey(symbol))
{
_characters[symbol] = new Character(symbol);
}
return _characters[symbol];
}
}

Real-world example (ShopNest)

ShopNest’s NotificationFactory creates Email or SMS senders based on user preference.
