Flutter Development Team

Our youngest team, the Flutter Mobile Developers. Risky and confident people who are fine to take responsibility and dedicate themselves to cutting edge technology. Doing things no matter what and how - that's the moto. We can do non-trivial things like text recognition, translation, ML, native libraries added to flutter projects, AR, and many others. We are proving that Flutter is suitable not only for pet projects such as booking bikes, etc. any longer. It is already available as a fully functional, rapidly improving technology with a very healthy community. It's here for at least the next decade to defeat the ReactNative, Cordova, and other dead evolutionary branches.
