Excited to see our Flutter experts taking the stage at the mDevCamp conference in Prague on June 4! 🚀

Kamil Sztandur and Agnieszka Forajter will present: “Flutter Refactors at Scale: Change Everything, Break Nothing.” ✔️

Refactoring a Flutter app is one thing. Refactoring across multiple repositories, dozens of developers, and production-grade systems used by thousands of users? That’s a completely different challenge.

Drawing from their experience working on large-scale applications - including complex banking platforms - they will share practical approaches to improving code quality without compromising stability.

On May 23, our Engineering Lead, Marcin Dardziński, together with SAP Developer Tech Lead, Adrian Dengusiak, will give a talk at the SAP Inside Track Conference in Wrocław, Poland. ✨

Their talk 👉 Flutter meets SAP: Native Mobile Apps the Clean Core Way

SAP offers multiple mobility approaches - from MDK to BTP iOS/Android SDKs - but none fully close the gap between native flexibility, OData support, and affordable expertise. During the session, Marcin and Adrian will show how Flutter and a custom Flutter SAP SDK, backed by a CAP BFF on BTP, deliver a Clean Core side-by-side extensibility approach to SAP mobile development.

SAP Inside Track is a community-driven conference created by SAP experts for the SAP ecosystem.

The organizers: Capgemini Polska and Uniwersytet WSB Merito Wrocław - wcześniej Wyższa Szkoła Bankowa. 🙌

🚀 Flutter Warsaw #21 - Join us - May 26th in Warsaw - for Accessibility & AI-Assisted Testing Talks 🚀

This time, we prepared two practical and technical talks focused on topics that are becoming more and more important in Flutter development: accessibility and AI-assisted testing.

🎤 Artur Wiśniewski – Technically Accessible, Actually Usable – A11y for 1M MAU in Practice

Artur will share practical lessons from building accessible banking apps, showing how screen reader users really navigate mobile apps, what improves their experience, and what makes them leave. He will also cover real-world accessibility challenges.

🎤 Oskar Zając – AI-Assisted E2E Testing in Flutter with Patrol MCP

Oskar will show how Patrol MCP enables faster and more reliable AI-assisted E2E testing in Flutter by allowing AI agents to interact with the app under test, inspect native device elements, and rerun tests on demand without rebuilding the app each time.

After the talks, stick around for snacks, free beer/soda, and networking! 🍻

Join us on Tuesday, May 26th, at Świetlica Wolności (Nowy Świat 6/12, Warsaw). Seats are limited, so secure your spot now! 👉 Sign up here: https://www.meetup.com/flutter-warsaw/events/314781160/

🎥 What happens when product and tech truly work as one team? Watch a case study about Activy & LeanCode.

Activy is a Polish wellbeing app that turns physical activity into a game - encouraging employees to cycle instead of drive and build healthier habits together. 300K+ downloads. 4.7⭐ rating.

But those numbers didn’t come from “just building an app.” They came from continuous evolution and real tech partnership.

From day one, LeanCode has worked closely with Activy as a long-term tech partner - not just executing tasks, but understanding their business, challenging ideas, and shaping the product together.

We are a tech partner of Nubank!

Nubank isn’t just another fintech. It’s the world’s largest digital bank outside Asia, serving over 130M+ customers 🎉 and continuously redefining what modern financial services look like.

Founded in 2013, they’ve built their position by challenging the status quo with proprietary technology and bold product thinking across Latin America.

Nubank has also been a pioneer in adopting Flutter at scale. Back in 2019, they made a move that many enterprises were still hesitant to take and proved that Flutter can power massive, high-quality systems without slowing innovation. 🚀

As they’ve said themselves, Flutter was a game-changer for their ability to scale, and that impact is still visible today as they expand into new markets.

Now, we’re proud to be part of that journey. 🙌 Building, learning, and pushing boundaries together.
