[Flutter] Android getting error: Namespace not specified

I decided to use latest version of Gradle and after updating AndroidManifest.xml and build.gradle I get this error and I couldn't solve it

Error:

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.
