If I remember correctly, ACF returns NULL if the field is not set, but you might want to double check me on this.
Anything like
if ($isState) {
// true
} else {
// false or NULL
}
will be false for either null or false. The main problem with having unset true false fields comes in if you want the default value to be true. If that’s the case then you can do something like this
if ($isState === NULL || $isState) {
// true
} else {
// false
}
