namespace missed

[MohammedFlutter]

please add in build.gradle file
android {
namespace 'xyz.justsoft.video_thumbnail'
}

FYI, I think is related to the version of the com.android.application plugin, and affects a lot of third party packages. I didn't encounter this issue on some existing older flutter projects that use an older version of this plugin. I'm using the below and it compiles just fine.

plugins {
    id "com.android.application" version "7.3.0" apply false
    // ...
}

Had the same problem

* What went wrong:
A problem occurred configuring project ':video_thumbnail'.
> 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.

This fork provides a solution :)
