Steps to reproduce

When passing --no-hot flag to disable new hot-reload on web, the flag doesn't seem to be working. With the flag and hot-reload disabled, doing a hot-reload should actually do a hot restart like it used to before. But instead, it does hot reload regardless it seems.

Steps:

  • Run flutter run -d web-server --no-hot.
  • In the console, Press r (Shift+r) for hot restart and it works fine.
  • In the console, press r and it should also do hot restart but rather does hot reload.

Expected results

When --no-hot flag is passed, hot reload and hot restart both should be the same like it used to before hot-reload support on web.

Actual results

When --no-hot flag is passed, it still does a hot-reload.
