I also created the possibility of connecting with Firebase and I want if I connect as a worker I will switch to a certain screen and if I connect as an employer I will switch to

问题 Im building a chat feature for my app using Firestore. I'm using limit(toLast:) because I'm fetching based on the timestamp, this method gives me the latest messages saved in my DB.
