The Flutter vs React Native dilemma isn’t really a dilemma as of Q1 2018. Flutter is less than a year old, with just a handful of apps using it. In the meantime, React Native has been around since 2015, and it powers complex mainstream applications like Facebook, Skype, Instagram, Bloomberg, and Discovery VR.
That said, Flutter looks promising. It’s fast and productive, and it’s the default UI framework for Google’s upcoming Fuchsia OS. Basically, Flutter appears to have what it takes to become a worthy React Native competitor in the foreseeable future.
So how do the two compare?
