When I install Fuchsia for Flutter development on VS Code, I have to set up Dart pkgs. I don't have any idea about it. I'm lost. Exactly, implementing this https://fuchsia.googlesource.com/fuchsia/+/master/docs/development/languages/dart/mods.md Any tutorials?
There is no need to install Fuchsia at all given that you are trying to build Flutter apps. While Fuchsia uses Flutter in some areas, the opposite is not true. There is no need for or reliance on Fuchsia if you would like to build flutter apps.
Open up Flutter.dev and click the blue "Get Started" button in the top right. Then follow the steps and you should be on your way.
Good luck.
