                        Add react 18 as peer dep
I have tested on my react-18 based app (forcefully installed using --legacy-peer-deps) and all form-array related functionality is working as expected. There is no code related to useEffect of which the behaviour has changed in react-18 during development on StrictMode. So it looks safe to update the peer dependency only.
Same here! Also using legacy peer deps and not having any issues!
@Stuey61296 and everyone using for React-18, you might want to look at https://github.com/final-form/react-final-form/issues/1009.
Published fix in v3.1.4.
