firebase/flutter: Multiple where queries-CodePudding

I have a collection with one array that holds userId's.

I know I only have 2 users in the incoming array. I tried the following snip but I am getting an error

  Future getChat({required List<String> userIdsArr}) async {
    print('userIdsArr[0]:  ${userIdsArr[0]}');
    print('userIdsArr[1]:  ${userIdsArr[1]}');

    var data = await chat.where(
        'User ids', 'array-contains-any', ['firebase', 'react']).snapshots();

    print(data);
  }

error I am getting here is

Error: Too many positional arguments: 1 allowed, but 3 found.
lib/…/cloud/firebase_cloud_storage.dart:44
Try removing the extra positional arguments.
    var data = await chat.where(
                               ^

CodePudding user response：

The syntax for building a query in Flutter is slightly different. If your chat is a query or collection reference, the array-contains-any would be:

chat.where('User ids', arrayContainsAny: ['firebase', 'react'])

Also see the Dart/Flutter code sample for array-contains-any in the documentation.
