As we know, the core of react-native uses Java and Objective-C to integrate with the native platform, however it is very common new projects / resources developed in Kotlin and Swift. Another thing is that the technologies have interesting new ways to create UI with Jetpack Compose and SwiftUI. It could be very interesting if the docs explained a lot more how to integrate this type of technologies in react-native. I believe it will be easier for the developer to create your own integrations or custom libraries giving more power to their projetcs.

I heard about CSS Grid Layout "Display: grid" So I wonder if React Native could support it

Hello, Please could you expand the Share API to also allow users to share files? This could take the form of renaming the existing share() method to shareText() and making a new shareFile() method that implements this. Please could you also ensure you can send a message with a file, for example a caption for a photograph providing its context or extra information? This feature would have real-world applications that would save users time in a great number of different apps. Thank you!

On Android, there is TextView's textIsSelectable. On iOS, there is UITextView's selectable. These allow one to click-and-hold to select text in a non-editable text view. It would be nice to expose this feature through React-Native's <Text>

It would be great if HTTPS requests made via the Fetch API could use the client certificates on the target device to authenticate if requested / required. This would allow strong authentication of clients built using React Native alone.

I haven't seen any mention on the ability to create Android home screen widgets with react-native. Are there any plans for it? Is this something to be included in core to include or should the community jump on it?

Headless JS is very useful for running background jobs and it would be nice if it worked for iOS as well. It is already supported for Android: https://facebook.github.io/react-native/releases/next/docs/headless-js-android.html

TextInput component with multiline={true} should show a vertical scroll indicator while actively scrolling the input, and when its size changes due to a new line (if height is not fixed). Described above is implemented on iOS but not on Android, at least for react-native init projects.

I'd love to have display: flex and border-radius: 50% to have auto-sizing circles on the scene

React Native start to be mature enough to think about adding the ability to place, executed in parallel, some controller's scripts in different threads. The one and only bottle neck of React Native is the slowing performance on view building and animations due to the single Javascript thread. We see appearing here and there different node modules that could be merge into React Native core. I specifically think about: for the workers: https://github.com/devfd/react-native-workers Hamster for the multithreading engine: http://www.hamsters.io Starting developing on that direction makes huge changes in the app. If those libs were included in Core, there's maybe a way to start threads transparently by placing specific markers at the head of the JS Classes? React-Native is awesome and have all to be the next cross platform language for web and mobile. But in the near future, when the applications will be complex enough, the criticism will rapidly comes from the lack of speed and smooth transition that make all the difference between an 100% Native App and a 80% Native React-Native App...
