I would like to begin to create a new application, which will probably be complex in terms of UI and I am hesitating between Flutter and React Native. In your opinion, which one is the best ?

For what use case? As long as it's a crud and display app, either works. For anything beyond that, it will rapidly decay into needing native impls.

If you know native I don't know why you wouldn't choose that.

I say that as someone who likes to dabble with React Native.

@SortOfTested it is theorically a display app. My question is more about performance issues

@N00bPancakes I want to avoid to write android native code because it is simply hell, and I don't want to maintain two different apps

@Tounai in that case I concur with sortoftested, if you're not looking for ultra performance, nothing wrong with React Native.

Really though from my personal experience, I think the most important thing is to be sure to use what you will enjoy enough to finish it ;)

React native because google bad.

@hashedram
Google bad, Facebook worse 🤷‍♀️

Simple how fast do you want to be productive?

If fast then use react native
Else use react native and learn dart aside
