[Flutter Web] Non-default entrypoint breaks run command #38797
Description
I've missed exact moment, when after upgrading flutter web is completely broken again
After running flutter run -d chrome I see only "Build application for the web..." in terminal and following error in JS console:
Failed to load resource: the server responded with a status of 404 (Not Found)
require.js:143 Uncaught Error: Script error for "main_web_entrypoint.dart.bootstrap"
