Make errors

[Big-Mande]

I was able to use the make get command but running the make command give me these errors: tool/lib/src/book.dart:118:56: Error: The method 'listSync' isn't defined for the class 'Glob'.

similar situation, I downgraded the dart to 2.19 so make-get works but then make doesn't work. Were you able to fix it? Edit: figured out that on dart 2.19.6-1 the make get and make clox seems to work.

How did you do that exactly? I'm not from ecosystem and can't seem to figure this out.

Okay, I just followed the errors and updated them by hand (thought there must be a command for this) this is updated one, but not sure if it breaks anything -

installing dart v2.19.6 works for me

Installing dart v2.19.6 also worked for me in the following way: brew reinstall dart@2.19 (I had already installed 3.5 so had to uninstall that as modifying the links didn't work for me) then echo 'export PATH="/opt/homebrew/opt/dart@2.19/bin:$PATH"' >> /Users/Jeremy/.zshrc per the recommendation of brew itself source ~/.zshrc and I was good to go
