Flutter build appbundle --release

[VasMaxence]

Hello,

When I tried to run flutter build appbundle --release I got this error :

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.

• What went wrong:
  A problem occurred configuring project ':device_calendar'.

Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

 If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

Do you have an idea how I can fix ?

PS: I used latest version of package and android :

ext.kotlin_version = '1.9.21'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath 'com.android.tools.build:gradle:8.1.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.4.0'
}

Already Fixed in the development build, you can wait a new release or if you want to fix you need to fined the build.gradle of this packed in your local computer and add this new line:

namespace 'com.builttoroam.devicecalendar'

inside of android
