TypeError: undefined is not a function

Hi. I copied the example and ran it in my application. Everything looked ok. Then I just scroll up to the bottom of the list and immediately scroll down to the top of the list and oops ... Maybe I missed something?

Did you solve it this problem?

[vladimircherevko]

I resolved this way: copied the code and added in line 126 if (onEndReachedInPromise.current && onEndReachedInPromise.current.finally).

Hi there😄, I'm having the same issue. It seems to be caused by the finally method not being defined.
Could be the case only for hermes engine. Using a polyfill for Promise.finally solves the problem.
