如何在 FieldArray 的对象中正确写入单选按钮值？

如何解决如何在 FieldArray 的对象中正确写入单选按钮值？

我有一个带有复选框和单选按钮的动态表单，对于复选框，它可以完美运行，所选值保存在正确的对象中。我需要单选按钮的相同行为

单选按钮示例 enter image description here

我需要一个看起来像这样的对象

{
  "questions": [
    {
      "questionId": 1,"question": "question1","questionVariants": [
        {
          "variantId": 1,"variantName": "name1","checked": "name1"
        },{
          "variantId": 2,"variantName": "name2"
        },{
          "variantId": 3,"variantName": "name3"
        },{
          "variantId": 4,"variantName": "name4"
        }
      ]
    }
  ]
}

但现在我明白了

{
  "questions": [
    {
      "questionId": 1,"variantName": "name2"
          "checked": "name2"
        },"variantName": "name3"
          "checked": "name3"
        },"variantName": "name4"
        }
      ]
    }
  ]
}
