This composable refers to QForm wrapping your own custom component which you want to communicate with.
Syntax
import { useFormChild } from 'quasar'
setup () {
// function validate () { ... }
// function resetValidation () { ... }
useFormChild({
validate, // Function; Can be async;
// Should return a Boolean (or a Promise resolving to a Boolean)
resetValidation, // Optional function which resets validation
requiresQForm: true // should it error out if no parent QForm is found?
})
}
