[troller2017]

Hello is there, i am facing errors just after importing the package on new project. I am hoping to use this but is this project even active? thank you.

A problem occurred configuring project ':flutter_sequencer'.
> 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.

I manged to solve up to the build but something went wrong with cmake()
[CXX1429] error when building with cmake using pub.dev\flutter_sequencer-0.4.4\android\CMakeLists.txt: --
