The Flutter Gold dashboard does not currently support notifications.
This is a sticking point in the case where:

• Pull request 1 lands, changing pre-existing golden file A
• Triage is not completed to approve the change
• The change ignore expires
• Pull request 2 picks up change to golden file A from master
• Pre-submit checks for PR 2 fail since there is no approved match for updated golden file A

This is not an often occurring case, as golden files are not changed often (they are visual constants!), and triage breakdown is also uncommon with considerate ignore practice.

To address this case, I would like to implement a notification system, likely through flutter/cocoon, that will ping PRs or directly email ignore owners before they expire, closing the potential gap for triage breakdown. This notification would encourage the owner to either

• triage images (if change has landed)
• extend ignore (if change has not landed)
• delete ignore (if triage has been completed, or if the change is not actually ready to land)
