Flutter / FireStore : Get the ID of the document just created in Collection

Question

I am adding data in Firestore with User > Accomodation collection. Firestore is automatically creating a new document in the collection Accomodation with all the details I haved added. But now I need to get the id of the document that he has just created to pass it to another screen. Should I create my own Accomodation ID or is there a way to get it ?

FirebaseFirestore.instance
.collection('Users')
.doc(uid)
.collection('Accomodation')
.add(data);

The User can have multiple Accomodation already created, I need to get the one just created.

Solution

after adding a document you will get a document reference, with this reference you can get id, i don't know is that method names changed or not after new patches but solution must be similar to that

DocumentReference docRef = await 
FirebaseFirestore.instance
.collection('Users')
.doc(uid)
.collection('Accomodation')
.add(data);
print(docRef.documentID);

The User have an ID? You can use this ID and then access to the object inside.

Yes the User has an ID, but he as multiple Accommodation already. I need the latest created.

This depends on how you create the Acomodation colection in Firestore, but you should create this with Auto Id, so when a new is created already have an ID.

Great, it works, thanks !! Correction : docRef.id
