Intro to React Native (and Why It’s Not Flutter) (PL) - Szymon Chmal
React Native lets you build iOS and Android apps with React — but forget everything you know about web dev. No HTML, no CSS, and a rendering system that’s nothing like the DOM. We’ll talk about what makes React Native tick, how it compares to good ol’ web React, and why its cross-platform strategy is *nothing* like Flutter’s. If you've ever tried one and wondered about the other, this is your crash course.

One Codebase, Multiple Platforms? Let’s Talk Cross-Platform Development!
Cross-platform development is reshaping how we think about mobile apps. Building once and running everywhere sounds like a dream — but how close are we to that dream in reality?
During this event, we’ll dive into the real-world challenges and trade-offs of writing apps that work across iOS and Android. You’ll get insights from both business and technical perspectives, compare different strategies, and see how cross-platform tools are changing the way developers ship apps today.
Why Should You Join?
Learn when cross-platform development makes sense — and when it doesn’t.
Explore common pitfalls and misconceptions that pop up when building for multiple platforms.
See how different approaches handle rendering, performance, and developer experience.
Ask questions, share your own experience, and connect with fellow mobile devs in the community.
After the talks, join us for a Q&A, open discussion, and some casual networking with your local dev crew.
