Code

protected function valueSubmit($form, FormStateInterface $form_state) {
    // Drupal's FAPI system automatically puts '0' in for any checkbox that
    // was not set, and the key to the checkbox if it is set.
    // Unfortunately, this means that if the key to that checkbox is 0,
    // we are unable to tell if that checkbox was set or not.
    // Luckily, the '#value' on the checkboxes form actually contains
    // *only* a list of checkboxes that were set, and we can use that
    // instead.
    $form_state->setValue([
        'options',
        'value',
    ], $form['value']['#value']);
