I tried everything people wrote on this problem and nothing worked. I have two apps, one was designed originally for web and one for mobile. I compared their codes in the web related parts - it's the same. the web one works, the mobile doesn't. I went through all the discussion here about it and couldn't find the problem.
the only clue that I have is that when I run the app on web, it doesn't even start to run my main.dart file. Or maybe it is, I put a breakpoint my main function and it never reaches it. it stops on a file named web_entrypoint.dart. The file has a "Future main()" function that starts and then throws the error.
Thank you!
