[cloud_firestore] Nested arrays are not supported

[AttalliAyoub]

Describe the bug

can't query nested array in firestore

i was trying to query this:

_db.collection('chats')
    .where('owners', whereIn: [[_me, _he], [ _he ,_me]])
    .orderBy('createdAt', descending: true)
    .limit(2)

but i I've got this bug report:

E/flutter (13152): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(error, Invalid data. Nested arrays are not supported, null)
E/flutter (13152): #0      StandardMethodCodec.decodeEnvelope

E/flutter (13152): #8      _ForwardingStream._createSubscription  (dart:async/stream_pipe.dart:93:16)
E/flutter (13152): #9      _ForwardingStream.listen  (dart:async/stream_pipe.dart:88:12)

To Reproduce
just query this:

_db.collection('chats')
    .where('owners', whereIn: [[_me, _he], [ _he ,_me]])
    .orderBy('createdAt', descending: true)
    .limit(2)

Expected behavior
this code is working on the web and i'm using it my my angular app.
i'll get the chat document.

Additional context
thanks

[AttalliAyoub]

also i'm asking if there is a documentation for c++ method channel

[iapicca]

Hi @phoelapyae69
can you please provide your updated flutter doctor -v
and your flutter run --verbose?
Thank you

If you are looking for calling functions from c++
you may want to look into this docs

[trunghvbk]

Hi, I'm encountering the same issue here.
Just call the query
final querySnapshot = await _firestore.collection(FirestoreCollection.chat).where('emails', whereIn: [[widget.user.email, widget.friend]]) .getDocuments();

Note that: It's happening on android emulator and working fine on iOS simulator.
Thank you!

I have the same issue.

It's happening on android, but working fine on iOS.

[Ehesp]

As the error messages explain, nested arrays are not supported in Firestore so the query is not valid.

[jcamilorm902]

@Ehesp These kind of queries should be supported by firebase android plugin because of this Google documentation:

https://firebase.google.com/docs/firestore/query-data/queries#in_and_array-contains-any

You can use an array value as a comparison value for in, but unlike array-contains-any, the clause matches for an exact match of array length, order, and values. For example: citiesRef.where('region', 'in', [['west_coast', 'east_coast']]);

that section gives an example for Java Android, Kotlin, Java that should be supported by this flutter plugin:

CollectionReference citiesRef = db.collection("cities");

Query query =
    citiesRef.whereIn(
        "regions", Arrays.asList(Arrays.asList("west_coast"), Arrays.asList("east_coast")));

In iOS plugin section this is supported. It should work in the same way in both platforms.

Nested arrays must be supported in these kind of queries!

[Ehesp]

Oh yeah, let me reopen and take a look.

[Ehesp]

Hi this is now fixed via #2913
