In my blogapp ,I am trying to implement comment system in flutter using cloud firestore. Each document is a post and I am trying to add comments as a subcollection to each document. How can I access each document id so that I can access the subcollection ?
Here I tried to print the document id below but it shows error NoSuchMethodError: 'id' method not found Receiver: null Arguments: [] :
final ref = await FirebaseFirestore.instance
.collection('blogs')
.add({
'title': titleController.text,
'body': myController.text,
'author': name,
'date': DateFormat('dd/MM/yyyy,hh:mm')
.format(DateTime.now()),
})
.then((value) => successAlert(context))
.catchError((error) =>
errorAlert(context));
titleController.clear();
myController.clear();
print(ref.id);
}
This is my firestore database :

You need to have access to the document id inside blogs, and access it’s collection and the add your data like this…
await FirebaseFirestore.instance
.collection('blogs')
.doc(documentId) // you need to enter this document id
.collection('comments').add({
'title': titleController.text,
'body': myController.text,
'author': name,
'date': DateFormat('dd/MM/yyyy,hh:mm')
.format(DateTime.now()),
})

Take a look in Flutter Firebase documentation.
It contains all the basic information to understand how Flutter interacts with Firebase.
Maybe later i could help more. Luck!
