firebase - How to increment existing number field in Cloud Firestore

Question

I have a field which indicates the number of transactions. I would like to increment it by 1 as soon as a transaction occurs. I could'nt find any method to directly execute this.

One method is to get the user first and then update the field with the received value + 1, but this is too lengthy and slow.

Can anyone tell me any other feasible method?
