ING Wholesale Banking migrated its mobile application from native Android and iOS to Flutter — this session shares the real story: strategic decisions, technical challenges, and honest results.

We'll cover why we chose Flutter for enterprise banking, how we approached the migration, and the challenges of security and compliance review in a regulated environment. We'll also dig into a question every enterprise team hits: what do you do when Flutter alone isn't enough? We rely on platform channels and platform views to keep certain native UI and logic in place. You'll see where and why we drew that line, and how we integrated Flutter with existing native infrastructure. We'll close with team transformation — what changed for Android/iOS specialists — and what worked (and what didn't).
