Two longtime friends with complementary skills meet a new mobile SDK for building high-performance apps from a single codebase, what could go wrong? Flutter is quite powerful but with great power comes great responsibility. Using widgets, building a meaningful UI in a new way, finding that library we need and getting used to a different architectural approach are some of the many challenges we face as developers and designers when going into the cross-platform world. In this talk, we'll review some of the advantages of using Flutter, how to tackle common challenges when adopting it and how can it spark a better collaboration between designers and developers, including roles and responsibilities, a well-defined feedback process, and our own experience while building an app. Interested?
