Is there a replacement for validFieldsRef in v7?

[MaxMcNally]

In our codebase, which is using RHF v6, someone wrote some code that relies on the validFieldsRef of the control object. It doesn't seem to exist in v7, so I need to find a replacement. I wrote some code that attempts to replicate the functionality -

export const getValidFields = (
  formValues: Record<string, any>,
  getFieldState: UseFormGetFieldState<Record<string, any>>
) => {
  const fields: Record<string, boolean> = {};
  for (const field of Object.keys(formValues)) {
    const fieldState = getFieldState(field);
    if (!fieldState.invalid && fieldState.isDirty) {
      fields[field] = true;
    }
  }
  return fields;
};

It doesn't seem to work the same though. I think the problem is with isDirty. Any ideas how to replicate this functionality?
