Namespace not specified. Specify a namespace in the module's build

 Problem:   I face this problem when I update my flutter project , 

ERROR : 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: C:\Users\aktarul ahsan\AppData\Local\Pub\Cache\hosted\pub.dev\flutter_sslcommerz-2.3.6\android\build.gradle. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

Solved:   find the location which path are show. just add a namespace . 

Solution: 

android {
    compileSdkVersion 34

    if (project.android.hasProperty("namespace")) {
        namespace = "name of package"  // change your package name like com.aait.testforplugin
    }
