Every new account in Cloud Firestore has a member ID.

I have an doc in a separate collection called memberIDgenerator with an “int = 0001” in Cloud Firestore.

How can I get this integer and assign it to a TextEditingController, or a string/int that can be assigned in order for me to be able to create new account and not have to manually type in the corresponding memberID.

I am able to easily update the int 1, but It has been quite difficult in being able to assign this int to a controller or a string that can be assigned to create an account The int has to stay in Firestore since there will be two devices creating accounts, hence, I can’t store it in the device.

Any advice? Thanks in advance!
