BEF 7.0 compatible

+1 for this. It was reported in 🐛 Nondescript error when trying to edit Exposed Form Style settings in view Active guess we can technically remove the typehints but would like to keep them if possible

the same on 7.0.1
php8.3.10
D10.3.2

tried to set select2 in bef via direct editing of views config (for field_country_target_id filter)

      exposed_form:
        type: bef
        options:
          submit_button: Apply
          reset_button: true
          reset_button_label: Reset
          exposed_sorts_label: 'Sort by'
          expose_sort_order: true
          sort_asc_label: Asc
          sort_desc_label: Desc
          text_input_required: 'Select any filter and click on Apply to see results'
          text_input_required_format: null
          bef:
            general:
              autosubmit: false
              autosubmit_exclude_textfield: false
              autosubmit_textfield_delay: 500
              autosubmit_hide: false
              input_required: false
              allow_secondary: false
              secondary_label: 'Advanced options'
              secondary_open: false
              reset_button_always_show: false
            sort:
              plugin_id: default
            filter:
              combine:
                plugin_id: default
              field_country_target_id:
                plugin_id: bef_select2
                advanced:
                  placeholder_text: 'Country'
                  rewrite:
                    filter_rewrite_values: ''
                    filter_rewrite_values_key: false
                  collapsible: false
                  collapsible_disable_automatic_open: false
                  is_secondary: false

when viewing the page frontend it goes into the same error:

Fatal error: Declaration of Drupal\select2\Plugin\better_exposed_filters\filter\Select2::defaultConfiguration() must be compatible with Drupal\better_exposed_filters\Plugin\better_exposed_filters\filter\FilterWidgetBase::defaultConfiguration(): array in /var/www/unh-new/web/modules/contrib/select2/src/Plugin/better_exposed_filters/filter/Select2.php on line 74

changing
public function defaultConfiguration(): array { to public function defaultConfiguration() { gives no reluslts

🐛 Compatibility with Better Exposed Filters 7 RTBC is a duplicate of this issue.

Patch in https://www.drupal.org/project/select2/issues/3482698#comment-15827078 🐛 Select2 Plugin is not compatible with BEF plugin Active fixes this issue for me in BEF 7.*
