No signature when building Chatty application

[BrianMwas]

I have run all the necessary commands to get started and even shifted it to the new embedding system but it still does not run. It gives off this error
What went wrong:
A problem occurred evaluating project ':app'.

No signature of method: build_9ciku1zpbujrrz24comy0tc8b.android() is applicable for argument types: (build_9ciku1zpbujrrz24comy0tc8b$_run_closure2) values: [build_9ciku1zpbujrrz24comy0tc8b$_run_closure2@6ed2056c]

Hi @BrianMwas
as you can see in the Readme the project is not actively maintained. They were developed using older versions of our packages and Flutter.
