Android Firebase - Multiple steps but save only if

Question

In my process I've 3 steps :

• Upload photo in Firebase Storage
• Save data in node (mandatory)
• Save data in another node (optional)

Actually I save data with callback one by one like : step1 > step2 > step3

But if step2 fail I don't want to save anything. How can I do this ? Firebase transaction can help me ?
