🐛 Firebase packages don't fully support AGP 8

🐛 Bug report

While trying to upload our app to AGP 8, we were getting error logs like this:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':firebase_analytics'.
> defaultConfig contains custom BuildConfig fields, but the feature is disabled.

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

BUILD FAILED in 914ms

The following code snippet fixed the issue for us when building locally. In each plugin's android/build.gradle file, you have to add:

android {
    buildFeatures {
        buildConfig = true
    }
}

The same is mentioned as a solution here. But I am not sure if the fix need to be implemented from flutterfire client end or not, hence based on the report, I'll keep it open for team's input and attention.

@darshankawar let me know if this has to be implemented on flutterfire side. If so, I can submit a PR.

This is something plugins need to do, not the clients. Clients can only work around it.

What's the workaround? @wujek-srujek

[wujek-srujek]

You need to globally enable build config, like this in the gradle.properties of your project:

android.defaults.buildfeatures.buildconfig=true

This is just a workaround as it enables it globally, not just for the plugins that need it, and is scheduled for removal in AGP 9. See more in this comment #11266 (comment) by @darshankawar
