Call JavaScript function from native code

Question

I have a react-native app and want to integrate it with native SDK. At some point I need to call js function which will return me data, and this call I should make from native side. Here is the flow:

some iOS handler require more info
native layer calls js code
js code calculate/fetch required data
js code return data back to native code
native code receive data and continue working

Is it possible? There is a lib react-native-eval but may be there is more elegant way to do this?

Thanks @DheerajV.S. but both of them are work in order to deliver data or notify react-native from native layer. I need to pass data in reverse order — Alexei Malashkevich

There is currently no clean way of doing this. My suggestion would be to use either a Callback or an Event from native to JS to notify that there is some information needed and to then invoke a function from JS to the native code that gives the required data to the native layer.
