"""Write an open Shorebird artifact proxy manifest.
|
|
|
|
The artifact proxy expects this file at:
|
|
|
|
/shorebird/<shorebird-engine-revision>/artifacts_manifest.yaml
|
|
|
|
It maps a custom Shorebird engine revision back to the upstream Flutter engine
|
|
revision for unchanged artifacts, and lists the artifact paths that should be
|
|
served from the open Shorebird mirror.
