This was a fun project to make. I used flutter to make the UI and firebase handles the firebase backend processes like the game, chats and storage. Features of this game includes the basic cards included in the game, and also music, chats, friend feature, ability to edit number of cards and user statistics.

Firebase storage, firebase realtime database, and firebase firestore were used. Firebase storage was used to store audio files, and profile pictures. Firebase realtime database was used to handle user data and communication of game state. Firebase firestore was used to handle the chats.

Since the parsed state class was too large, I had to only include the elements which had been changed, reducing the size of the state object sent to the other players. Secondly, the logic was really hard to implement as it one move doesn't just involve a player putting down a card. It also involves the player choosing another player, choosing another card, etc.
