Artifact Proxy

This is a tool for proxying Flutter artifacts from a derived Flutter engine revision back to the base Flutter engine revision. This is useful for when you need to modify some of the Flutter artifacts but not all of them.

This is a development tool which map requests to Google Storage (either Shorebird's bucket or the official Flutter buckets).

Usage

Uses config.yaml to configure the engine revisions and artifact overrides.

# Run locally with hot-reload enabled.
DEV=true dart --enable-vm-service run bin/server.dart

And then in a separate terminal:

FLUTTER_STORAGE_BASE_URL=http://localhost:8080 flutter precache -a

You should use a separate checkout of Flutter when running this, so you don't poison the cache of your main Flutter checkout.
