Doc/setup: How can i pull this down and run it

Since .android is in the .gitignore file, the include_flutter.groovy is not in github and this project will not run.

What is the best way to solve this? I'm trying to use submodules or perhaps even checkin a .aar file... Thanks!

Start by reviewing the .gitignore entry for .android and the missing include_flutter.groovy file. Check the documented or reproducible setup for pulling the project and integrating Flutter, including the submodule and .aar alternatives mentioned in the report. Done means a fresh checkout can run successfully.
