Travis Flutter Integration Tests (Android Integration Tests not working | Code Coverage is not separated for this Mono Repo Setup)

travis_flutter_integration_tests.yml

# This is part of a custom mono repo setup I have.
# The folder structure is basically divided into an `app` and a `packages` folders.
# Codecov logging to codecov.io should be improved. Right now, it overwrites the previous one.
# Everything works except for the last stage, the Android Integration Tests.
# Working to make the Android tests work seems like a nightmare because of different
# versions incompatibility, something Apple does much better.

Stick to everything but the iOS and Android Integration Tests if you want to be more practical. Unless integration tests are crucial to your app of course...
