1. /vendor/laravel/framework/src/Illuminate/Database/Eloquent/SoftDeletingScope.php

   $builder->onDelete(function (Builder $builder) {
       $column = $this->getDeletedAtColumn($builder);
   
       return $builder->update([
           $column => $builder->getModel()->freshTimestampString(),
       ]);
   });
   

2. /vendor/laravel/framework/src/Illuminate/Database/Eloquent/Builder.php

   if (isset($this->onDelete)) {
       $closure = $this->onDelete;
   
       return $closure($this);
   }
