Hey @thalesfsp @loeffel-io I'm not sure why we've reopened, this has been asked many times in other issues.

TL;DR required checks if the field is its default value NOT if it exists, if you need an existence check the data type itself will need to be nullable, in this case tri-state, but bool by itself only has 2 states.

Please see #319

P.S. would love some help documenting this somewhere as it tends to keep coming up.
