🐛 [firebase_core_web 1.7.0] is not working for web on flutter master channel

[Alecia1997]

Receiving the following when running on web (Master Channel) -> Error: Assertion failed

[flutterninja9]

I fixed it by passing "options" in Firebase.initializeApp() method

@Alecia1997
Do you get same error using previous version of it ? firebase_core_web: 1.6.6 ?
If not, then it could be related to an ongoing issue with flutter_core_web that you can follow-up in for further updates.

Not getting the same error when using the previous version - Firebase_core_web: 1.6.6.
Wil have a look at the referenced links you provided above
Thank you!

I have the same issue on the web using flutter stable version 3.0.2.

In the project, firebase_core is defined as

firebase_core: 1.19.1

Note there is no symbol (^) before the version number. It means I want to use this version strictly.

This version 1.19.1 uses

firebase_core_platform_interface: ^4.4.3
firebase_core_web: ^1.6.6

Note: firebase_core_web version is ^1.6.6.
It means when getting the dependencies, it can be 1.6.6, 1.6.7, 1.6.8, 1.6.9, and so on.
But it should not be 1.7.0.

When I build the project, it is taking firebase_core_web: 1.7.0
Please check the attached screen from CI (CodeMagic).

Due to version 1.7.0, the web build is not working.

The question is why the dependency version is resolved to 1.7.0

is this correct behavior?

UPDATE:
I think the above behavior is correct. If either patch or minor version is updated then the dependency is resolved to a higher current available version of the same major version.

It seems that JS SDK V9 is used now which is the cause of this issue.
It was better to update the major versions of the packages so that previous versions continue to work fine.

[deepak786]

I had to downgrade all the web dependencies to make the project work on the web.

firebase_core_web: 1.6.6
firebase_auth_web: 3.3.19
firebase_analytics_web: 0.4.0+17
firebase_database_web: 0.2.0+17
firebase_storage_web: 3.2.19
firebase_messaging_web: 2.4.4
firebase_remote_config_web: 1.0.16
cloud_firestore_web: 2.6.19
cloud_functions_web: 4.2.18

@Alecia1997 also getting the same error. Downgrading all packages seems like the only way at the moment. @google-oss-bot Please advise on a different solution

[darshankawar]

This could be related to web JS SDK v9 which is the current version for which an issue is filed that you can track:
firebase/firebase-js-sdk#6445

I am able to replicate the same error as mentioned here: #9106 (comment)

It seems that we have to pass the Firebase options when initializing the Firebase from the dart side using Firebase.initializeApp().

[russellwheatley]

Yes, you have to pass FirebaseOptions for the web platform. flutterfire configure will write the file, and you just have to import the generated options file and pass into options for Firebase.initializeApp().
