Some were developed by a single Flutter dev, some came into light through collaborative efforts across multiple teams. Each of them was different. Each of them presented unique challenges and taught us invaluable lessons. In this talk, we invite you to explore different approaches to architecting Flutter apps. Central to our narrative will be the concept of architectural drivers - key factors or priorities that steer our decisions about how the app is structured and designed. We'll show how we leverage our experience when approaching new projects. Drawing from our successes and failures, we'll present our current Flutter stack which enables us to craft robust, scalable, and maintainable applications. While there is no silver bullet for Flutter architecture, we can still have some sensible defaults. Why do we use BLoC for state management? Why not Riverpod?

If you recognize some of those questions, I am happy to add another couple: What are passkeys? Or how about: How to use passkeys to replace passwords in an Android app? In this workshop I will walk through the later two questions: How to build an Android App that registers and signs users in, using passkeys. Expect a quick explanation of this fancy new technology, why it will replace passwords and how you can store them either on your mobile devices or on dedicated hardware. Following that, a fictive application and service will be built to show you how to use those passkeys and which moving pieces you will need.

Learn Flask the hard way by diving into architectural patterns. Discover how to build scalable and maintainable applications using Repository, Unit of Work, and Use Cases. Don't miss this opportunity to become a Flask pro! devfest-berlin-2024-58356-learn-flask-the-hard-way-introduce-architecture-patterns Shahriyar Rzayev en Flask is a popular and flexible web framework for Python, but building scalable and maintainable Flask applications can be challenging without a solid understanding of architecture patterns. This workshop aims to provide participants with a detailed explanation of applying architecture patterns to Flask projects. By exploring various design principles and best practices, attendees will learn how to structure their Flask applications for improved scalability, modularity, and maintainability. Focusing on the Repository, Unit of Work, and Use Cases patterns, attendees will gain experience in applying these patterns to enhance code organization, maintainability, and testability. All these layers are wired together using Dependency Injection, which is yet another powerful tool to use in your applications. The application we are going to build is stored in: https://github.com/ShahriyarR/hexagonal-flask-blog-tutorial We are going to completely rewrite the official Blog application described in Flask documentation by applying architecture patterns. All abstraction layers are covered by unit and integration tests, which will give the attendees a detailed view of why it is important to structure the application using architecture patterns. false https://pretalx.com/devfest-berlin-2024/talk/738DRH/ https://pretalx.com/devfest-berlin-2024/talk/738DRH/feedback/
