How to Use Vuelidate With Conditional Validation

I was building a form with Vue and Vuelidate.
My goal was to pass a prop that would turn a field into a required field.
Vuelidate has a validator `requiredIf` which can make the field optionally or conditionally required.
prop: {
active: {
type: Boolean,
default: true
}
},
validations: {
field: {
required: requiredIf(function (field) {
return this.active
})
}
}
