The plugins cloud_firestore, cloud_functions, firebase_core... firebase_storage use a deprecated version of the Android embedding

[davemg3]

Bug report

The plugins cloud_firestore, cloud_functions, firebase_core, firebase_dynamic_links, firebase_storage, flutter_image_compress, flutter_secure_storage, map_launcher, package_info, qr_code_scanner, smart_auth use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Steps to reproduce

Updated my Flutter environment from 2.5.x to 3.3.8 and got the error above on a working project
It was working well on friday after the migration and suddenly on saturday impossible to do "flutter get"

Please provide a feedback as this is a stable version. Does someone encounter this issue too?

Hi @davemg3, we're using Flutter 3.3.8 and Android V2 Embedding, you might want to run flutter clean and ensure that all the other plugins are properly updated

[davemg3]

Hi @Lyokone

I have tested on 3 different previously working projects including one with few plugins as :

cupertino_icons: ^1.0.3
 collection : ^1.16.0
 firebase_core: ^2.2.0
 cloud_firestore: ^4.0.5
 firebase_auth: ^4.0.2
 firebase_storage: ^11.0.5
 cloud_functions: ^4.0.4
 google_maps_flutter: ^2.1.1

I did pub clean, pub get, reboot of mac, invalidate cache restart of android studio so many times this weekend but doesnt work anymore while everything was ok on 11/11

It seems not project related but maybe link to my android studio platform or the firestore plugin i catch in my external library when pub get.

Did you clean,get recently?

[davemg3]

I created a new Flutter project with only firebase_core: ^2.2.0 dependency

and updated Android Studio but still doesnt work. Any idea ?

@davemg3
In your above project, do you see below entry in manifest file ?

<meta-data
            android:name="flutterEmbedding"
            android:value="2" />

firebase_core plugin example already seems to be on v2:

https://github.com/firebase/flutterfire/blob/master/packages/firebase_core/firebase_core/example/android/app/src/main/AndroidManifest.xml

[davemg3]

@darshankawar , yes all my projects have been migrated to Android V2 according to the migration page and they all get this meta data

      <meta-data
            android:name="flutterEmbedding"
            android:value="2" />

Especially the empty test project created from scratch with only the firebase_core: ^2.2.0 dependency added gets also automatically this meta data in manifest file

[darshankawar]

Can you try by running the same project from terminal instead of from Android Studio and see if you still get same log ?

[davemg3]

Hi @darshankawar ,
If you mean pub clean/get from terminal instead of android studio, this is my preferred way so already done also (both way, same result with above empty test project)..:(

[davemg3]

@darshankawar , on an new project, i have tested with 3 firebase dependencies and found out the version level below above which it breaks :

   OK = > NOK
 1) firebase_storage: ^10.3.1 =>   firebase_storage: ^11.0.5
 2) cloud_firestore: ^3.5.1 => cloud_firestore: ^4.0.0
 3) firebase_core: ^1.9.24=>  firebase_core: ^2.2.0

All 3 cases, tested separately share the same breaking change and provide the same deprecated version of the Android embedding message :

BREAKING FEAT: Firebase iOS SDK version: 10.0.0 (#9708). (9627c56a)

Does this provide any clue?

For note : on my main project, all my firebase dependency got upgraded to latest version cause i was trying to solve the following issue, still pending from my side : #9231. I have also upgraded my dart sdk, flutter and android studio to latest version as per above Flutter doctor

Thanks for the update. Keeping this issue open for further insights from the team, as I am unable to replicate this behavior.

@darshankawar , thanks for direction
I have deleted the updated Flutter/Dart and reinstalled the same versions by downloading from official website
Ok now.
