Pass and validate object to Vue 2 component

I have Vue component with lot of props

<Field
        v-for="field in fields"
        :key="field.name"
        :name="field.name"
        :type="field.type"
        :label="field.label"
        :values="field.values"
        :value="field.value"
      />

I validate it this way

 props: {
  name: {
    type: String,
    required: true
  },
  label: {
    type: String,
    required: true
  },
  type: {
    type: String,
    default: 'text'
  },
  value: {
    type: String,
    default: ''
  },
  values: [Object]
}

So, I want to pass all properties as one object eg

<Field
    v-for="field in fields"
    :key="field.name"
    :params="field"
  />

How can I validate and return default values for properties of this object?
