    'vue/require-valid-default-prop': 'error',

};

What did you do?

<template>
  <div></div>
</template>

<script lang="ts" setup>
const {
  example = [],
} = defineProps<{
  example?: number[];
}>();
</script>

What did you expect to happen?

When assigning default values to props via props destructuring, arrays do not need to be generated by a function, and probably the same with objects. The vue documentation on props destructuring includes an example: https://vuejs.org/api/sfc-script-setup.html#reactive-props-destructure

I expected example = [] not to trigger the vue/require-valid-default-prop rule error.

What actually happened?

/home/projects/stackblitz-starters-reg1dy/test.vue
  8:19  error  Type of the default value for 'example' prop must be a function  vue/require-valid-default-prop
