The frontend_server package is used by both the flutter command line tool and the frontend_server_client package (used by webdev and package:test).
Changes to the command line API or behavior should be tested against the follwing test suites (in addition to normal HHH testing):
Otherwise these changes will need to be carefully coordinated with the flutter tooling and frontend_server_client teams.
This API stability does not cover any of the source code APIs.
- The frontend_server kernel compilation and expression evaluation for kernel should be considered “stable”.
- Specific flags like the --flutter-widget-cache may be added for experimentation and should not be considered stable.
