Flutter vs Swift

We built the first version of our app with RN and it turned out a mess in a while. A lot of bugs along with poor performance out of the box for a fairly large app. Many things, that native platform has, cannot be done with existing solutions for RN. For instance, large titles on iOS are not fully implemented in any of existing navigations libraries. Also there's painfully slow JSON bridge and many other small, yet annoying things. On the other hand Flutter became a really powerful and easy-to-use tool. A bit of a learning curve, of course, because of Dart, but it worth learning. Flutter offers TONS of built-in features, no JSON-bridge, AOT compilation for iOS.

As an early stage startup, we needed to create the first version of our mobile application having in mind the future need of supporting multiple platforms (iOS & Android). We gave Flutter a try and immediately experienced a smooth and easy way to learn a mobile platform (with Dart) that allowed us to very quickly create our mobile app. The more we learn, the more we can leverage the ecosystem of libraries/plugins for Flutter (https://pub.dev/), the more we foresee Flutter as a very good choice for cross platform mobile development. In comparison, Android (Java) and iOS (with Swift) are powerful languages but they both have a steep learning curve. With Flutter we only had to learn one platform and voilà !

While with Ionic it is possible to make mobile applications with only web technologies, Flutter is more performant and is easy to use if you are willing to learn Dart, which is a fun language. Plus, it has awesome documentation and, while its ecosystem isn't near as big as JavaScript's is, it has a good package manager called Pub and its packages are generally high quality.
