[add-to-app] error : Namespace not specified. Please specify a namespace in the module's build.gradle #126403
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
Create a new android app and add a new flutter module to it using steps in option 2 : https://docs.flutter.dev/add-to-app/android/project-setup
run 'flutter pub get' in module to build .android folder
sync project in android studio
Expected results
build is successful
Actual results
app fails to build.
Android studio is looking for 'namespace' setting in .android/build.gradle. adding a value manually makes the app build but this is a generated .android folder so any further runs of 'flutter pub get' to update dependencies remove any edits.
Error happens with 3.7.12-stable and 3.10.0-1.5.pre-beta
error output:
* What went wrong:
A problem occurred configuring root project 'Android'.
> A problem occurred configuring project ':flutter'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
> Namespace not specified. Please specify a namespace in the module's build.gradle file like so:
android {
namespace 'com.example.namespace'
}
If the package attribute is specified in the source AndroidManifest.xml, it can be migrated automatically to the namespace value in the build.gradle file using the AGP Upgrade Assistant; please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.
