building for web fails with an error

[KevinCCucumber]

I just implemented OpenID into my app and now I get this error when launching on the web:

Launching lib\main.dart on Chrome in debug mode...

                                  ^^^^^^^^^^^
Failed to compile application.
Exited (sigterm)

I tried rebuilding with only "openid_client_browser" imported in my files, but it still failed wich means that the package is unusable for web deployment
