我有一个使用 React Native 开发的应用程序。我在登录和注册屏幕上使用react-hook-form。我有一个自己创建的验证模式。我无法将此验证方案与react-hook-form控制器的规则一起使用，因为我无法分配输入值，请帮忙！

const formKeys = {
    email: 'email',
    password: 'password',
  };

  const {
    handleSubmit,
    control,
    formState: {errors},
  } = useForm();

<Controller
                control={control}
                name={formKeys.email}
                render={({field: {onChange, value}}) => (
                  <InputFields
                    errorMessage={errors[formKeys.email]?.message.toString()}
                    value={value}
                    onChangeText={onChange}
                    autoCapitalize={'none'}
                    placeholder={t('common:email')}
                    image={
                      <View style={styles.userIconsStyle}>
                        <EmailIcon/>
                      </View>
                    }
                  />
                )}
                rules={{
                  required: emailValidation() //input value required here,
                  minLength: minLengthValidation(validationSchema.email.minLength),
                  maxLength:maxLengthValidation(validationSchema.email.maxLength),
                }}
              />

/*validation schema*/

export const emailValidation = (v: string): boolean | string => {
  const {t,i18n}=useTranslation();
  const emailRegx = /^[a-zA-Z0-9]+@[a-zA-Z0-9]+\.[A-Za-z]+$/;
  if (v) {
    return emailRegx.test(v) || `${t('common:errorMessages:invalidEmailAddress')}`;
  } else return `${t('common:email')} ${t('common:errorMessages:isRequired')}`;
};
