javascript - 从单独的组件重置条件渲染

Question

以前我使用该函数showUsers并{isSubmitted && showUsers(userData)}在 graphql 查询后有条件地呈现一些项目。在这种情况下，我正在使用

setIsSubmitted(false);
setUserData(null);

在按钮上重置数据并停止条件渲染。但是，现在我已经转移showUsers到Users一个单独的组件。在这种情况下，我想不出一种方法来传递setIsSubmitted和setUserData。我想修复它，以便在突变运行后，渲染应该消失。

注释掉的部分是我之前使用的。

export const AddContactTry: React.FunctionComponent = () => {
  const validationSchema = phoneNumberValidationSchema;

  const { values, handleChange, handleSubmit, dirty, handleBlur, isValid, resetForm, isSubmitting, setSubmitting, touched}= useFormik({
    initialValues: {
      phoneNumber: '',
    },
    //isInitialValid:false,
    validationSchema,
    onSubmit: (values: FormValues) => {
      handleSubmitForm(values);
    },
  });

  console.log('isDirty', dirty);
  console.log('isValid', isValid);
  console.log('phone numm', values.phoneNumber);
  console.log('submitting status', isSubmitting);

  const [isSubmitted, setIsSubmitted] = useState(false);
  const [userData, setUserData] = useState<UsersLazyQueryHookResult>('');
  const navigation = useNavigation();

  const _onLoadUserError = React.useCallback((error: ApolloError) => {
    Alert.alert('Oops, try again later');
  }, []);

目前，如果突变成功，我会看到警报，但渲染的项目仍然存在。
