A Completed Functional Flutter App - FindSeat (BLoC + Json API + Unit Test + Firebase Auth)
I’m Android Developer and I’m working in a software company in Vietnam. I have experience in both kind project: outsourcing project and product project. I decided to study Flutter, because I believe it’s promised in future. As experienced developer, I care about clean architecture, testing, performance and maintainability that why I keep searching for an example of completed application. Unfortunately, community now full of project such as speedcode, UI challenges, … it’s just small pieces of real world application. In fact, most of the project doesn’t have fancy UI like that. That why I build this project by myself and now share it to the community, I hope you can get something from it then apply to your work.The first version of project (v1.0) is just about UI + simple logic. In this version v2.0, I applied BloC pattern by using Flutter Bloc to project and also have unit tests for it. I also built simple Mock API for the app, it just static json file uploaded to a my private hosting. I hope I have time to do cache local data by SQLite but I have not, so hope next version will be soon available.Check the soure code herehttps://github.com/KhoaSuperman/findseat

Why are not all widgets stateful?
Presumably, stateless widgets are more efficient in some way, which is why they exist. If so, what specifically makes them more efficient?I understand what stateful and stateless widgets are, this is a question about internal implementation.

My first flutter app
Hey everyone,I don't know whether this post belongs here, but I finished making my first actual project with Flutter. It's an app which compiled quotes from ancient greek and stoic philosophers. As of now, it is only on Android but I'm planning to release on the App Store soon. For those of you who are on Android, can you please try out the app on the Google Play Store? Appreciate it!
