Setting the namespace via a source AndroidManifest.xml's package attribute is deprecated.

Steps to Reproduce

Make sure you're on the master channel.

flutter create example --platforms android
flutter build apk --config-only
cd android
./gradlew :app:assembleDebug

Expected results:

A fresh, flutter created project should not have any Gradle warnings. This warning will become an error in future AGP versions.

Actual results:

I see a deprecation warning.

$ ./gradlew :app:assembleDebug
> Task :app:processDebugMainManifest
package="com.example.example_gradle" found in source AndroidManifest.xml: /Users/bartek/dev/bartekpacia/example_gradle/android/app/src/main/AndroidManifest.xml.
Setting the namespace via a source AndroidManifest.xml's package attribute is deprecated.
Please instead set the namespace (or testNamespace) in the module's build.gradle file, as described here: https://developer.android.com/studio/build/configure-app-module#set-namespace
This migration can be done automatically using the AGP Upgrade Assistant, please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.

> Task :app:stripDebugDebugSymbols
Unable to strip the following libraries, packaging them as they are: libflutter.so.

I think there are 2 action items:

easy: change the template files to define namespace in build.gradle, and not in AndroidManifest. See Fix Gradle warning in a freshly flutter createed Android project #122290 for an example.
harder: write a migration so all existing projects get this change. We can also tell developers to use AGP Upgrade Assistant in Android Studio.

Thanks for the report. I am able to replicate this behavior on latest master. On stable flutter build apk --config-only option is not supported.

I'll try to submit a PR for this soon. Can this be somehow assigned to me?
