Thank you for the video! It was very easy to follow and understand. May I know how can I allow the users to edit the comment?

[@droidmonk4820]

Glad that you liked it.
To allow user to edit comments , first you will need to authenticate the users, then using a form allow the users to enter new data and finally update the corresponding data on the firestore database.

Plz make video on how delete collection with sub collections

[@droidmonk4820]

Do you want to delete a complete collection from the app itself?
According to the official documents--
"Deleting collections from the client is not recommended."
Let me know your use case, and I'll try to find the best solution for you.

FirebaseFirestore.instance.collection('mujarrabaat_e_tabib').doc(widget.docId).collection("index").doc(widget.documentId).snapshots();
thanks for your guidance.... your content so much better and easy to understand....
sir can you solve this query using stream builder???

[@droidmonk4820]

You have to do something like ------
Stream streamData=FirebaseFirestore.instance.collection('mujarrabaat_e_tabib').doc(widget.docId).collection("index").doc(widget.documentId).snapshots();
....
...
StreamBuilder(
stream:streamData;
builder: (context,snapshot){
Map data=snapshot.data();
return ;
}
)
I hope this helps.
