Flutter: Building with plugins requires symlink support

 Building with plugins requires symlink support.
Please enable Developer Mode in your system settings. 

Run  Start ms-settings: developers  to open settings.

 

Installation of some plugins required a special allowance. This requires permission for windows which is available in For Developer. It is much like Install from unknown source type permission.

How to allow permission:
Search Developer Settings in the start menu and open it. Under developer, mode click on Install apps from any source, including loose files. Run pub-get again and you are good to go.

 

If you feel uncomfortable turning on Developer Mode to allow sideloaded apps and you aren't targeting Windows OS, you can avoid doing flutter pub add package_name. Instead, clear out the old package with dart pub remove package_name manually edit your pubspec.yaml with the dependency, and do a flutter pub get.
