Namespace not specified. Specify a namespace in the module build file

Question

I have worked on a flutter project in 2023. I was facing errors with gradle settings. I managed to migrate the gradle settings following the official Flutter documentation(https://docs.flutter.dev/release/breaking-changes/flutter-gradle-plugin-apply). Now, I am facing another error, highlighted in the attached screenshot. I have specified the namespace as per official documentation(https://developer.android.com/build/configure-app-module#groovy). Is there a way around to fix it?enter image description here

Apparently this is a known issue, this issue occurred in older versions of flutter due to outdated or deprecated packages.

Possible resolution:

add the script to android/build.gradle or android/build.gradle.kts:

subprojects {
   afterEvaluate { project ->
       if (project.hasProperty('android')) {
           project.android {
               if (namespace == null) {
                   namespace project.group
               }
           }
       }
   }
}

If these changes do not solve your problem, read this problem here carefully, I think it will solve your problem.
