Can't run flutter run -d chrome test/foo_test.dart #49838
Description
From DevTools, I run this:
$ flutter run -d chrome test/flutter/table_test.dart
Launching test/flutter/table_test.dart on Chrome in debug mode...
Configuring `build_web_compilers:entrypoint` in target `devtools_app:devtools_app` but this is not a known Builder
Building application for the web... 15.0s
Attempting to connect to browser instance...
And nothing happens. Chrome starts and the logs show this error
main.dart.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)
I suspect that the tool needs to adjust the index.html file opened in Chrome to run the test script.
