Google’s Flutter = React + Java Swing
David Ford

Flutter has a long way to go, though. After starting to develop an app, I had found many interactive bugs. Also, there is no way to use a database engine like SQLite just yet. I’ve found a few repos on Github that addresses the lack of data storage features in Flutter, but I haven’t been able to get them to work within my own project yet. I moved away from Flutter to React Native and had found a very similar coding style within React, but the UI in React doesn’t compare to Flutter in the slightest bit. In fact, no other cross-OS development platform I’ve tried can compare to Flutter. Their UI is gorgeous and is so easy to build upon. Can’t wait until Flutter goes into beta.
