Recently i started to notice warning in my workflow when using Flutter Build step

Error (non fatal) says

Collecting cache
Failed to collect flutter cache, error: package resolution file (/Users/vagrant/git/.packages) not found, error: stat /Users/vagrant/git/.packages: no such file or directory

From what i was able to understand how this step works [ i'm very bad with go, sorry :( ] its failes at this line https://github.com/bitrise-steplib/bitrise-step-flutter-build/blob/master/cache.go#L215.

It's trying to find .packages directory but it does not exists (not even on my local machine.

https://dart.dev/tools/pub/cmd/pub-get#package-resolution says that .dart_tool/ is the place to look for package_config.json

and
https://dart.dev/tools/pub/cmd/pub-get#the-system-package-cache that .pub-cache is at root dir unless env var(PUB_CACHE) is set (https://dart.dev/tools/pub/environment-variables).

.dart_tools/

Again step does not fail but it would be nice to speed up build time a bit with cache. If this is just warning sorry for bothering.

I don't think it's just a warning. The push-cache step isn't recognizing any cache related to Flutter packages.

Hi @damian-molinski and @abdulhaq-e ,
we merged a PR to fix this issue and released a new version (0.16.0) with the changes.
Could you please check if the issue still exists?

Looks good to me 👍
