Flutter Berlin × CarOnSale

Join us for an evening of Flutter, Dart, and networking hosted by CarOnSale. We'll kick things off with a deep dive into one of Dart's newest language features, followed by a second session and plenty of time to connect with fellow developers from the Berlin Flutter community.

Schedule

18:30 — Doors Open
Check in, grab a drink, and meet fellow Flutter developers from the Berlin community.

19:00 — Welcome Notes
A short introduction from Flutter Berlin and our hosts at CarOnSale.

Talk 1 — Hiding Complexity with Dart Extension Types — Roman
Extension types in Dart 3.3+ let you elegantly hide the real complexity behind clean abstractions. They enable powerful patterns for true compile-time singletons with strong privacy guarantees, while also letting you build robust zero-cost Value Objects that enforce domain invariants and create a clear ubiquitous language — all with zero runtime cost.

About Roman
Roman is a Google-awarded Flutter Developer and Staff Mobile Engineer at CarOnSale.de, where he has worked for 4 years as part of his 8 years of Flutter experience (and over a decade in design). He loves Dart as his primary language and Rust as a complementary one (along with TS/Swift), but believes strong programming fundamentals matter more than any specific syntax. In his role he mentors Flutter developers and shapes architecture solutions. Outside of work he prioritizes family and open-source.

Talk 2 — Beyond Chatbots: When AI Owns the Interface - Esra Kadah
In this session, we will examine the architectural evolution of AI integration within Flutter applications. We will start with traditional deterministic widget trees, transition to structured data generation where models populate predefined client layouts, and finally explore generative UI.

About Esra
Esra Kadah is a Senior App Developer at Antigua Mobile, GDE for Flutter and Dart, co-author of Flutter Design Patterns & Best Practices (Packt, 2024), and one of the organizers behind Flutter Community AI Circle(FCAIC), Flutteristas and Flutter Berlin Meetup.

With a strong foundation in software development and a deep interest in UI/UX and design psychology 🧠, she focuses on building user-friendly, human-centered mobile experiences. Her work sits at the intersection of engineering, creativity, and empathy.

Esra is an active contributor in the global 🌍 Flutter and AI ecosystem. She explores how tools like Gemini, ChatGPT, Cursor, Firebase Studio, MCP, agentic workflows, and multimodal prompt engineering 🤖 are transforming the way developers build, scale, and reflect.

She has worked on international projects, contributed to open source, and presented at events from Istanbul to Berlin, Paris, Stockholm... and the U.S. Blending code, content, and community with intention and care.

20:30 — Networking & Socialising
Meet fellow Flutter developers, exchange ideas, discuss the talks, and connect with the local community.
22:00 — Doors Close
We wrap up the evening and head home inspired with new ideas and connections.
