在循环内反应 forwardRef

Question

我正在尝试使用 react forwardRef 在一堆子组件中调用一个函数。这是代码。

const WorkoutFeedbackForm = ({
  latestGameplaySession,
  activityFeedbacks,
  selectedActivityIndex,
  setIsReady,
}) => {
  const [isLoading, setIsLoading] = useState(false);
  const workoutRef = createRef();
  const refMap = new Map();

  const onSubmitFeedbackClick = useCallback(async () => {
    setIsLoading(true);
    await workoutRef.current.onSubmitFeedback();
    for (let i = 0; i < activityFeedbacks.length; i++) {
      const activityRef = refMap.get(activityFeedbacks[i].sessionID);
      console.log(activityRef);
      if (activityRef && activityRef.current) {
        activityRef.current.onSubmitFeedback();
      }
    }
    setIsLoading(false);
  }, [
    activityFeedbacks,
    refMap,
  ]);

  return (
    <>
      <FeedbackFormContainer
        key={`${latestGameplaySession.id}-form`}
        name="Workout Feedback"
        feedback={latestGameplaySession.coachFeedback}
        isSelected
        gameplaySessionDoc={latestGameplaySession}
        pathArr={[]}
        ref={workoutRef}
      />
      {activityFeedbacks.map((feedback, index) => {
        const activityRef = createRef();
        refMap.set(feedback.sessionID, activityRef);
        return (
          <FeedbackFormContainer
            key={feedback.sessionID}
            name={feedback.name}
            feedback={feedback.coachFeedback}
            isSelected={index === selectedActivityIndex}
            gameplaySessionDoc={latestGameplaySession}
            pathArr={feedback.pathArr}
            setIsReady={setIsReady}
            ref={activityRef}
          />
        );
      })}
      <FeedbackSubmit
        onClick={onSubmitFeedbackClick}
        isLoading={isLoading}
      >
        Save Feedbacks
      </FeedbackSubmit>
    </>
  );
};

问题是 createRef 似乎只适用于循环外的组件。你知道这里有什么问题吗？还是不可能做到这一点？
