Smooth card animations can make an app feel more interactive and polished. ✨ Built this Flutter UI to create seamless transitions and a better user experience.

Even big apps like @instagram can have small UX issues, I noticed a case where pressing back once doesn't work you need to tap twice to exit a section. Seems minor, but these small frictions can impact user experience.

So I finally finished this weather app I've been working on and wanted to share it here.
Honestly this project started just to practice BLoC properly because I kept avoiding it and using setState
for everything 😅.

Flutter Folder Structure I use for scalable apps 🚀
Feature first + Clean Architecture for clean, testable & production ready code.
Works great as the app grows and in team projects.
Open to feedback would love to know how you structure your Flutter apps 👀
