Filament: Delete Attachments when Deleting a Record

Filament does not delete uploaded files when user deletes the record. Modify getActions() function in the edit page as below:

protected function getActions(): array
{
    return [
        Actions\DeleteAction::make()
            ->after(function (YourModel $record) {
                // delete single
                if ($record->photo) {
                    Storage::disk('public')->delete($record->photo);
                }
                // delete multiple
                if ($record->galery) {
                    foreach ($record->galery as $ph) Storage::disk('public')->delete($ph);
                }
            })
    ];
}
