React Hook useEffect has a missing dependency: 'xxx' ?

Problem

Hi, I am researching React Hook recently, it's great. But I have a problem, I did not find a suitable answer in the React Hook documentation and google to solve my problem. When I used a function in useEffect and function component together, I encountered a warning that I did not specify a dependency in useEffect, as shown below: Is there any way to solve my problem? I have thought about it for a long time. What is the current behavior? [code block] Mini repro in codesandbox: https://codesandbox.io/s/trusting-kowalevski-oet4b Any solution, thanks.
