Flutter developer : optimization of chat

I'm looking for a flutter developer for an optimization. Indeed, I have an embeded chat system in my application and I use STREAM (Flutter feature) to load conversations and keep them updated whenever a new message is received.

I'm using Firebase/Firestore as database for conversations and messages in the backend.

Currently, I'm facing a serious performance issue with my "support account" of the application because it has so many conversations. Please let me your thoughts and what kind of quick fix you can make to improve the performance.

Important, it should be transparent for the users, all features should remain.

Thanks you in advance for your suggestions.

Regards, Imad
