Flow error with react render method

Question

I ran into the error below while trying to add some flow type checking to one of my test apps.

I don't really understand what it means nor how to fix it.

render(): ?React.Element {

error:

Element: 
Application of polymorphic type needs <list of 1 argument>. (Can use `*` for inferrable ones)

Let me know if you need more code (maybe class definition etc).

Answer 1

It seems now we should to write Element<any> insted just Element

Nonconformity

Flow Docs and github.com/facebook/react-native/blob/… – Nonconformity

I wonder why React is using <any> instead of <Object>. My understanding of Flow's doc suggests this would be better: flow.org/en/docs/types/any – Factorize
