[firebase_database]: web no result when listening to multiple onValue streams on the same path

[robindijkhof]

Is there an existing issue for this?

• [X] I have searched the existing issues.

Which plugins are affected?

Database

Which platforms are affected?

Web

Description

Listening to the same path multiple times will only return a result to the latest stream. Please take a look at the example below for more info. This worked fine in firebase_database 10.5.0 with firebase_core: 2.28.0 but is now broken in firebase_database: 11.0.2 with firebase_core 3.1.1.

Reproducing the issue

Consider the following block

var ref = FirebaseDatabase.instance.ref().child('/somepath');

ref.onValue.listen((data) {print('got them 1');}, onError: (e) => print('error'), onDone: () => print('done'));
ref.onValue.listen((data) {print('got them 2');}, onError: (e) => print('error'), onDone: () => print('done'));
ref.onValue.listen((data) {print('got them 3');}, onError: (e) => print('error'), onDone: () => print('done'));

On web this will only print got them 3. On Android it will print got them 1, got them 2, got them 3

Listening to a subpath works fine though. So the following block works as expected:

FirebaseDatabase.instance.ref().child('/somepath').listen(...)
FirebaseDatabase.instance.ref().child('/somepath/sub').listen(...)

Seeing a similar issue, and I think it occurred with firebase_core 3.0.0.

[TarekkMA]

@robindijkhof Thank you for reporting this issue. I will inform the team, and we will work on finding a solution.

[russellwheatley]

Thanks for creating the issue. I have a PR to fix. FYI;, you're creating brand new streams for the same data, you could actually fix without my PR by doing the following:

// create a single stream
var ref = FirebaseDatabase.instance.ref().child('/somepath').onValue;

ref.listen((data) {print('got them 1');}, onError: (e) => print('error'), onDone: () => print('done'));
ref.listen((data) {print('got them 2');}, onError: (e) => print('error'), onDone: () => print('done'));
ref.listen((data) {print('got them 3');}, onError: (e) => print('error'), onDone: () => print('done'));

With this fix we are still facing this issue in debug mode on web.

No issue when testing in PROFILE mode on web.

Firebase versions

firebase_core: 3.2.0
