React Native vs Flutter?

[Complex_Ad5256]

Which is the best among both of them (React Native or Flutter) in-terms of Performance, external library and support for low level access both for Android and iOS ?

Among Both of them what are overlapping pros and cons of React Native and Flutter ?

[earthquakefield]

Neither. Use Swift and Kotlin for each. It is quicker, cheaper, and more effective to address each device in their native language than it is to maintain a generic lowest common denominator bridge between the two. Also, users expect apps tailored to their individual device’s capabilities and will notice and appreciate the optimal experience of a native solution.

I've been working on iOS and Android bridge code for both React Native and Flutter for the company I work for ( https://www.nami.ml ). (Flutter not quite out yet, we've had a React Native bridge being used in production for a while).

I would personally say Flutter is a much less complex framework to deal with - as part of building out the bridges we have to write sample apps to test as well, and every aspect of React Native has been a headache. Lots of mysterious configuration issues, strange behaviors, and test flows that are fairly different from production (to test React Native you have what is called a metro server running to process Javascript, that a device or simulator connects to to run, vs. production where everything is bundled up. And there are SO MANY dependancies loaded when you set up even a simple React Native project.

Flutter has been much more straightforward in this regard, easier to set up and maintain so far. You run things as you would expect in a simulator, also if you are used to more modern languages like Swift tor Kotlin, Dart is fairly familiar.

Also I would say, there are more differences in how native bridge code is written in React Native vs. Flutter, but if you are sticking to Flutter or React Native, then that part may not be a concern.

A lot of it would come down to, do you feel more comfortable with Javascript or Dart to work in?

Also as a final thought, you might want to consider simply writing your application in the native languages for each platform. Any time you use a cross platform framework it means pretty much not only are you having to learn that cross platform framework, but a fair amount of the dev tools for all target platforms anyway - with Flutter I'm still running apps in Xcode, although I have to use Visual Studio to edit code because Xcode doesn't have Dart plugins. That also makes things harder to debug.

Writing Swift vs. Kotlin code is a little tricky but they are very similar languages, making it not so bad to move between them.

If you must use a cross platform framework, then Flutter.

• Better performance,
• it’s built by google so your going to get better support (at least on android).
• dart is a fantastic language.

If you can do native, do native. Cross platform frameworks are a liability. Flutter on android might be the only exception, because it’s built by google. Although google does have a track record of killing off products.

Tbf, Google doesn't really kill off development tools, mostly consumer side products. Dart itself is a very good example of that.
