chat app

I’d like to share my latest project: a Chat App

I’ve always been curious about how real-time apps like WhatsApp or Messenger are built, so I thought — why not build one myself?

I decided to use Flutter for the frontend and Firebase for the backend. This experience really helped me dive deeper into Firebase Authentication to ensure security, and Cloud Firestore to handle real-time message synchronization.

My biggest challenge?

Making sure the UI updates instantly and smoothly with every new message — learning how to manage the controller properly so the ListView.builder scrolls automatically to the latest message, and adding animations for each new incoming message.

The best part? Seeing everything come together perfectly in real-time!

I’m really proud of what I’ve built and how much I’ve learned along the way.
