React Native auto focus next input on submit

Question

I have a form that is generated by the object, and the size is different each time.

I see other examples hard coding to make it jump to the next field. however that is the not gonna work for my case.

so my question is : How to make on onSubmitEditing jump to the next field when return key is clicked.

similar question : React Native: How to select the next TextInput after pressing the "next" keyboard button?

My tries: creating a list of useref in a list and passing correct index in to TextInput :

 var listOfRef =[]
 myObj.map( (item,index)=> listOfRef[index]=useRef())

but this giving me an error Rendered more hooks than during the previous render.
