* Demonstrates the ability to generate metadata when inspecting the
last accepted and delta components.
* Attach the metadata to the component right before compiling with DDC.
* Use the metadata to avoid deoptimizations in the initial compile
when they are only required to support a hot reload.
* Deletion of all type rules for classes that extend Object in the
initial compile. In the future this should be reduced further to
only the classes that had a hierarchy change in a hot reload.
* Type checks on the return value of getters used to represent
fields.

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).
API Stability
Changes to the command line API or behavior should be tested against the following test suites (in addition to normal HHH testing):
- flutter_tools: https://github.com/flutter/flutter/tree/master/packages/flutter_tools
- frontend_server_client: https://github.com/dart-lang/webdev/tree/master/frontend_server_client
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.
Stable subset
- The frontend_server kernel compilation and expression evaluation for kernel should be considered "stable".
- The frontend_server JavaScript compilation is semi-stable, but clients should anticipate coordinated breaking changes in the future.
- The frontend_server JavaScript expression evaluation is experimental and is expected to change significantly from Dec 2020 through the end of 2021.
- Specific flags may be added for experimentation and should not be considered stable.
