Summary

Fixes #34793.

We are allowing passing down effect events when they are inlined as a prop.

<Child onClick={useEffectEvent(...)} />

This seems like a case that someone not familiar with useEffectEvent's purpose could fall for so this PR introduces logic to disallow its usage.

An alternative implementation would be to modify the name and function of recordAllUseEffectEventFunctions to record all useEffectEvent instances either assigned to a variable or not, but this seems clearer. Feel free to suggest any improvements.

How did you test this change?

  • Added a new test in packages/eslint-plugin-react-hooks/__tests__/ESLintRulesOfHooks-test.js. All tests pass.
