Trying this with VS Code instead as I couldn't get it to work with Android Studios.
I am on windows 10 using Visual Studio Code version 1.85.1
I downloaded the code. Unzipped it into a directory.
Open VS Code and clicked Open Directory. Clicked on the directory I unzipped to.
Ran "Flutter pub get" and got the following screen shot.
Then I ran flutter packages pub run build_runner build --delete-conflicting-outputs
and got:
PS C:\Users\Chris\Downloads\rate_the_block> flutter packages pub run build_runner build --delete-conflicting-outputs
Deprecated. Use dart run
instead.
Could not find package "build_runner". Did you forget to add a dependency?

I am at a loss as where to go from here. I have googled this for days with Android Studio and VSC.
