Does RHF only validate fields when they are dirty?

[valerio-pescatori]

I have a useFieldArray of objects, every input of the object has a validation rule defined.
I also have an 'add item' button and I want it to be disabled if the array is not valid. I'm using getFieldState to check the validity of the array (yes, i'm correctly subscribing to errors in the formState), but the validation won't be triggered until I touch one of the inputs in the array, so the button appears enabled even if the form is not valid.

I tried combining the invalid and isDirty properties from getFieldState to disable the 'add item' button but this causes more problems (e.g if I pre-populate the form with values from a fetch request, it might be valid even if it is not dirty, so the button will be disabled while it shouldn't).

I also tried calling trigger to validate the fields when mounting the component or when appending an item to the array but it still won't change the invalid prop from getFieldState. Any ideas on how to solve this? thanks

it is hard to say what is happening without code/sandbox provided. It depends on the sort of validation you have, how you set up the form etc. If you can provide sandbox, that can help!

It's a very big and complex form, I'll try to reduce it as much as I can and post the sandbox asap! ty
