I am trying to use Flutter choice chips to act as a filter for firebase but I cannot seem to work out how to achieve this. It doesn't seem to present any errors, but it doesn't present any data so I am confused what I haven't done right here

_setupTasks(currentUserId, filters) async {
    if (kDebugMode) {
      print("Tasker Browsing: $currentUserId");
    }
    List<Task> tasks =
        await DatabaseService.getTasks(currentUserId, 'Posted', filters);
    if (mounted) {
      setState(() {
        _tasks = tasks;
      });
    }
  }

FilterChip(
                            showCheckmark: false,
                            checkmarkColor: Colors.white,
                            backgroundColor: Colors.grey[300],
                            label: Text(cat['name']),
                            selected: _filters.contains(cat.id),
                            labelStyle: TextStyle(
                              color: _filters.contains(cat.id)
                                  ? Colors.white
                                  : Colors.black,
                            ),
                            selectedColor:
                                Theme.of(context).colorScheme.primary,
                            onSelected: (bool value) {
                              setState(() {
                                if (value) {
                                  _filters.add(cat.id);
                                  _setupTasks(widget.currentUserId, _filters);
                                } else {
                                  _filters.removeWhere((String name) {
                                    return name == cat.id;
                                  });
                                  _setupTasks(widget.currentUserId, _filters);
                                }
                                if (kDebugMode) {
                                  print(_filters);
                                }
                              });
                            }),

static Future<List<Task>> getTasks(
      String userId, String status, List<String> filter) async {
    QuerySnapshot userTasksSnapshot = await tasksRef
        .where('status', isEqualTo: status)
        .where('ownerId', isNotEqualTo: userId)
        .where('typeId', arrayContains: filter)

        // .orderBy('timestamp', descending: true)
        .get();
    List<Task> tasks =
        userTasksSnapshot.docs.map((doc) => Task.fromDoc(doc)).toList();
    return tasks;
  }

Firestore doesn't support logical OR queries. You can instead make one query for each condition you want to match, and merge the results.

So turns out that the Filter Chips weren't sending an array like I had assumed from the logs. When I changed the arrayContains to whereIn this resolved the issue for anyone else looking to achieve a similar result
