Summary
PR references this issue
The HIR evaluation in ValidateNoSetStateInEffect.ts suffers from evaluation order dependence. The validator has to:
This means that if the callback for onSetState (which is a useEffectEvent function) is not evaluated by the time the useEffect hook is being evaluated, it will erroneously not throw "EffectSetState".
In order to solve this we can split the node discovery and the error reporting into 2 separate passes which ensures that by the time we are evaluating the errors we have a complete view of the HIR function, as opposed to reporting as we traverse it.
