- Updated AAR releaser test to use ShorebirdProcess.defaultFlutterStorageBaseUrl. - Changed macOS releaser test to reference a new troubleshooting URL. - Enhanced shorebird_yaml_test with deserialization for AOT patch metadata. - Modified network_checker_test to check self-hosted URLs from ShorebirdEnv. - Added tests for artifact paths in shorebird_artifacts_test. - Updated shorebird_cli_command_runner_test to reflect new repository URL. - Improved shorebird_env_test with additional tests for shorebirdRoot and engine revision fallback. - Adjusted shorebird_flutter_test to use environment variables for Flutter Git URL. - Updated shorebird_process_test to utilize default Flutter storage URL. - Enhanced shorebird_validator_test to link to the default hosted URL. - Updated shorebird_web_console_test to use the configured hosted URL. - Refactored code_push_client to use default hosted URL for API requests. - Updated README and generation scripts for the code_push_protocol package to reflect new OpenAPI spec source. - Modified shared.sh to allow configurable Flutter repository and storage URLs.

This server proxies requests for Flutter artifacts to the correct location,
|
|
depending on the engine revision. Most artifacts are served from the configured
|
|
Flutter artifact origin, but a few artifacts are served from the configured
|
|
open Shorebird artifact mirror to add support for code push.
|
|
</p>
|
|
<p>
|
|
See the workspace README and docs/CI.md for open artifact mirror details.
