Deprecated imperative apply of Flutter's Gradle plugins

[ablbol]

Recently, I saw the following change about "Deprecated imperative apply of Flutter's Gradle plugins". Currently in my android/build.gradle, I have the following code (related to issue #12156):

// Add this block to use android BOM: 32.5.0
project.ext {
  set('FlutterFire', [
    FirebaseSDKVersion: "32.5.0",
  ])
}

The code was suggested by @russellwheatley .

The docs in the link above does not say where we should place this code. Keeping the code in android/build.gradle creates compilation error. Could someone please suggest a solution.

@ablbol - I've just updated the firebase auth example which uses the declarative approach: https://github.com/firebase/flutterfire/blob/gradle-change-android-bom/packages/firebase_auth/firebase_auth/example/android/app/build.gradle#L29-L36

you can try on this branch: https://github.com/firebase/flutterfire/tree/gradle-change-android-bom

This is the build log:

Launching lib/main.dart on sdk gphone64 arm64 in debug mode...
Configured Firebase SDK Version: 32.5.0
✓ Built build/app/outputs/flutter-apk/app-debug.apk
Connecting to VM Service at ws://127.0.0.1:55640/_E5lQs3L8WY=/ws

It still works. Also - is there something that stops you from using the latest android BOM?

Hi @russellwheatley, Thanks for your suggested solution. It did work. I was placing the code at the top of the build.gradle file which was causing compilation problem.

The reason I am still using this code is when I removed it, I was getting email-already-in-use exception when linking auth providers, even though I have the latest code of all the packages that I am using. (this is the same problem described in #12156 that we discussed before). I believe you told me back then I should not see the "email-already-in-use" exception in the latest packages. But that is not the case. This is how my pubspec.yaml looks like.

Hi @russellwheatley, I changed my code so that linking of auth providers is done after the user logs in as suggested here. Also, I have enabled email enumeration protection as recommended. Finally, I used the following code in my android/app/build.grade:

// Add this block to use android BOM: 32.5.0
project.ext {
  set('FlutterFire', [
    FirebaseSDKVersion: "32.5.0",
  ])
}

Unfortunately, I am still getting email-already-in-use exception when linking auth providers.
I am afraid that enabling enumeration protection has caused this exception. Can you please suggest a solution to this.

Thanks for confirming it works, @ablbol. I'm closing out as the issue is resolved. Please open a new issue outlining the problem with reproducible steps, thanks 🙏
