Missing namespace Property Causes Build Failure with AGP 8.0+

[AliSamavi]

Hi,

I'm using the flutter_vpn package in my Flutter project, and I encountered a build issue when using Android Gradle Plugin (AGP) 8.0 or higher. Here's the error I received:

FAILURE: Build failed with an exception.

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

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.

The issue occurs because the namespace property is missing in the flutter_vpn package's build.gradle file. Starting with AGP 8.0, this property is mandatory.

To resolve the issue, I added the following line to the android block in build.gradle:

android { namespace = "io.xdea.flutter_vpn" // Other configurations }

It would be great if you could update the package to include this fix, so other users don’t encounter the same problem. Let me know if you need further information.

Best regards.
