Anna Gringauze f13285482d Fix expression evaluation failure after hot restart 
The lifetime of program compilers in JavaScriptBundler is too short,
moving the program compiler cache to FrontendCompiler instead
so the ProgramCompilers created during main compilation could be reused
for expression evaluation until the next compilation.

README.md

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 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.

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 like the --flutter-widget-cache may be added for experimentation and should not be considered stable.
