How do I get a shared value in Fastlane?

Question

I use the changelog_from_git_commits Fastlane action to gather a changelog from the commit logs. The output ends up in a FL_CHANGELOG variable:

Actions.lane_context[SharedValues::FL_CHANGELOG] = changelog

Now I would like to post the changelog along with my Slack notification:

slack(payload: { 'Changelog' => WHAT_DO_I_WRITE_HERE? })

What do I write there? ENV["FL_CHANGELOG"] didn’t work.

Answer 1

This worked:

payload: { 'Changelog' => Actions.lane_context[SharedValues::FL_CHANGELOG] })
