-    You can run custom logic using this hook after the widget filter form is updated:
-
-    ```php
-    public function updatedInteractsWithSchemas(string $statePath): void
-    {
-        // Runs after the form update is completed
-    }
-    ```

+The `$this->filters` array will always reflect the current form data. Please note that this data is not validated, as it is available live and not intended to be used for anything other than querying the database. You must ensure that the data is valid before using it.

     If you want to add filters that apply to multiple widgets at once, see [filtering widget data](overview#filtering-widget-data) in the dashboard.
