🐛 [cloud_firestore] FireStore Web query.startAfter actually runs startAt
Bug report
Describe the bug FireStore Web query.startAfter actually runs startAt
Steps to reproduce
Steps to reproduce the behavior:
In Flutter Web. Run a code to load query doc in pages.
Expected behavior
Like flutter firestore doc said:
Creates and returns a new [Query] that starts after the provided document (exclusive).
Sample project
/* firestore data structure
final Map<String, dynamic> newCmtDoc = {
'msg': cmtData, // String
'from_uid': user?.uid,
'to_uid': _post?['from_uid'],
'timestamp': Timestamp.now(),
'type': cmtType, // String
};
*/
DocumentSnapshot? _lastDocument; // Track the last loaded document
final int _pageSize = 10; // Number of items to load per page
Future<void> _loadCmts() async {
Query? query = db
.collection('comments')
.orderBy('timestamp', descending: true);
if (_lastDocument != null) {
query = query.startAfterDocument(_lastDocument!);
}
query = query.limit(_pageSize);
try {
QuerySnapshot querySnapshot = await query.get();
// Convert the QuerySnapshot to a List of DocumentSnapshot
List<DocumentSnapshot> cmtDocs = querySnapshot.docs;
if (cmtDocs.isNotEmpty) {
_lastDocument = cmtDocs.last;
}
if (!kReleaseMode) {
debugPrint('comments docs are : ${cmtDocs}');
}
for (var doc in cmtDocs) {
if (!kReleaseMode) {
// debugPrint('id is : ${doc.id}');
}
if (doc.exists && doc.data() != null) {
final cmtDocData = doc.data() as Map<String, dynamic>;
cmtDocData['id'] = doc.id;
// if (!_comments.any((comment) => comment['id'] == doc.id)) { // this line actually is a temp workaround
if (mounted) {
setState(() {
_comments.add(cmtDocData);
});
}
// }
}
}
} catch (e) {
if (!kReleaseMode) {
debugPrint('Error getting comments: $e');
}
}
}
Additional context
Issue not occurred in Android. It is in Web only.

@mhan8796 Can you check https://github.com/firebase/flutterfire/issues/7946#issuecomment-1090107428 and see if it helps in your case or not ?
@darshankawar Look similar, but In my case, I don't have a .microseconds() as timestamp. I just use Timestamp.now() as timestamp in the db. Is it not working in web?
@mhan8796 Check if this helps. If not, can you provide the runnable code in text format that we can directly use to verify it further ?
@darshankawar that post is to convert Timestamp to Datetime. I used that in my code but it is not related to this problem.
I updated my code to be text. so basically just that one loadCmt function. It goes through the db by pages. when it is empty, Android and iOS returns empty list [], while web returns last entry.
Thanks for the update. I tried using the code sample but maybe need the firestore structure as well that I can setup locally so as to properly retrieve the data as you reported. Can you provide a sample firestore structure ?

updated it in the original post. Let me know if you need anything else.
Sorry for coming back late on this. I tried to use the code sample you provided, but am unable to properly replicate the issue reported. So if you could provide us complete runnable code sample would be helpful further.
Also, revisiting the code sample, I see that you are using query.startAfterDocument and not startAfter which are two different methods.
`startAfter` : Takes a list of values, creates and returns a new [Query](https://pub.dev/documentation/cloud_firestore/latest/cloud_firestore/Query-class.html) that starts after the provided fields relative to the order of the query.
The values must be in order of [orderBy](https://pub.dev/documentation/cloud_firestore/latest/cloud_firestore/Query/orderBy.html) filters.
While startAfterDocument which you are using is https://pub.dev/documentation/cloud_firestore/latest/cloud_firestore/Query/startAfterDocument.html
@darshankawar thanks for reminding me. I forgot to comment out a line that serves as temp workaround for this issue. I now comment it out and added another print statement above it. Could you check again?
I just use scrollcontroller to call it.
_scrollController.addListener(() {
if (_scrollController.position.pixels ==
_scrollController.position.maxScrollExtent) {
_loadCmts();
}
});
ListView(
controller: _scrollController,
children: [
// bunch of text widgets
]),
Thanks for the update and patience. I am trying to include your code snippet in the plugin example so that I have runnable code, but it isn't letting me properly replicate it, thinking I might be missing to properly represent the behavior. Can you provide the code sample in terms of or with respect to plugin example itself so that we can make it issue actionable ?
Also, to make sure the implementation is correct, are you already following as below:
-
Given an ordered list of documents, the methods
startAtandstartAfterlet you move to the document with a specific field value in the list (not to a numeric offset within the list). -
you'd need to do something like orderBy('name').startAfter('three') to skip to the entries with a name field that is > 'three'.
@darshankawar I refactored the entire widget. Try this widget as a whole scaffold.
I am using startAtDocument code, not really startAt or startAfter, but I will keep them in mind for future reference.

Thanks for the update. Keeping the issue open for team's input on reported and expected behavior as I am not sure if this would be actionable from plugin side or from native.
I just tested this on iOS and web, the result was the same. I used this code to test:
// Last doc in collection
final docSnap = await FirebaseFirestore.instance
.collection('flutter-tests')
.doc('yoyoyoyoy')
.get();
print('object: ${docSnap.data()}');
final result = await FirebaseFirestore.instance
.collection('flutter-tests')
.startAfterDocument(docSnap)

print('RRRR: ${result.docs.length}');
Result for both platforms:
object: {name: John Something}
RRRR: 0
Not sure if this was fixed in web refactor for WASM support or wasn't an issue in the first place. Closing as there is nothing to fix.
