You can use FirebaseStorage.instance.refFromURL(url).delete()

like

onLongPress: ()async{
  await FirebaseFirestore.instance.runTransaction((Transaction 
 myTransaction) async {
    FirebaseStorage.instance.refFromURL(snapshot.data!.docs[index].get('url')).delete()
    await myTransaction.delete(snapshot.data!.docs[index].reference);
  });
},

                            return ListTile(
                              subtitle: Text('From: ${messages['sender']}'),
                              title: Text('Text: ${messages['text']}'),
                              tileColor:
