Issue Link:

What is the link to the issue this cherry-pick is addressing?

#179008

Changelog Description:

Explain this cherry pick in one line that is accessible to most Flutter developers. See best practices for examples

flutter pub get could be spawned multiple times on MacOS when pubspec.yamls outside of the project were modified after a flutter pub get in the root project.

Impact Description:

What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)

The widget previewer's file watcher can detect pubspec.yaml changes within plugin packages that are reachable via a symlink. This can cause numerous flutter pub get requests to be issued that aren't necessary and can possibly cause a user's machine to hang.
