Answer 1

You'll get this error if you try run a command from outside the root of your flutter project folder. Simply type pwd in your project terminal, and the command will output the full path of your working directory. In VSCode, you can quickly access the project root folder terminal by right clicking the folder then "open in integrated terminal".

Answer 2

You will get this error if you type 'flutter pub get <>' instead of 'flutter pub add <>' in the terminal
