🐛 [firebase_database] The .get() method ignores other query parameters such as `orderByKey()` and `equalTo()` #7437

Closed Tom3652 closed 2 years ago

Tom3652 commented 2 years ago

Bug report

Describe the bug

When using the FirebaseDatabase.instance.reference().child("noMatterWhat").orderByKey().equalTo("anything").get(), the whole list of values is retrieved and the equalTo is ignored.

In contrast with .once() that is actually working with everything.

.get() is ignoring any other query parameter such as : orderByKey(), orderByValue(), orderByChild() and equalTo().

I have already made an issue regarding limitToFirst and limitToLast, no matter using .get() or .once() : #7396.

Steps to reproduce

Steps to reproduce the behavior:

  1. Run the sample project it will create 5 messages.
  2. Click on the red square to see the result with .get() (when the query contains .equal("message1") as child.
  3. Click on the BackButton to clear the list
  4. Click on the blue square to see the result with .once() for the same query.

Expected behavior

I expect the .get() method to be working as the .once(). This doesn't really prevent from using firebase_database as the .once() is working, but this sound like a bug anyway.

Sample project

import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_database/firebase_database.dart';
import 'package:flutter/material.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(const TestApp());
}

class TestApp extends StatefulWidget {
  const TestApp({Key? key}) : super(key: key);

  @override
  _TestAppState createState() => _TestAppState();
}

class _TestAppState extends State<TestApp> {
  final List<Map<String, dynamic>> _messageList = [];

  void _writeMessages() async {
    for (int i = 0; i < 5; i++) {
      int time = DateTime.now().millisecondsSinceEpoch;
      FirebaseDatabase.instance
          .reference()
          .child("messages")
          .child("message$i")
          .update({"createdAt": -time, "content": "message$i"});
      await Future.delayed(const Duration(milliseconds: 500));
    }
  }

  void _queryWithGet() async {
    DataSnapshot snapshot = await FirebaseDatabase.instance
        .reference()
        .child("messages")
        .orderByKey()
        .equalTo("message1")
        .get();
    if (snapshot.exists) {
      print("Snap : ${snapshot.value}");
      Map<String, dynamic> result = Map<String, dynamic>.from(snapshot.value);
      result.forEach((key, value) {
        _messageList.add(Map<String, dynamic>.from(value));
      });
      setState(() {});
    }
  }

  void _queryWithOnce() async {
    DataSnapshot snapshot = await FirebaseDatabase.instance
        .reference()
        .child("messages")
        .orderByKey()
        .equalTo("message1")
        .once();
    if (snapshot.exists) {
      print("Snap : ${snapshot.value}");
      Map<String, dynamic> result = Map<String, dynamic>.from(snapshot.value);
      result.forEach((key, value) {
        _messageList.add(Map<String, dynamic>.from(value));
      });
      setState(() {});
    }

Thanks for the detailed report and code sample. I see the same behavior upon running with latest plugin version (^8.1.0) and on stable and master channel.

Are you able to try the latest plugin version and confirm if this is still an issue?

I have a feeling there's an underlying issue with this though on the official Firebase SDKs that we wrap - but would be good to confirm how the latest FlutterFire plugin version behaves - thanks

I confirm that this issue is fixed using : firebase_database: ^9.0.3.
