Changelog Description
Handle file system exceptions when symlinking across Windows file system drives with user-friendly message.
Impacted Users
Flutter developers on windows machines with their Flutter SDK installed on one drive and their app on another
Impact Description
If you try to run/build a Flutter app on one windows drive while your Flutter SDK is installed on another, the tool will crash while trying to symlink native directories the latter to the former with a cryptic error message (see #66224).
Workaround
Whether we CP this or not, the workaround is the same: move your flutter project to the same drive as your Flutter SDK.
This CP will instruct the user about the workaround, however.
Risk
low
Test Coverage
yes
Validation Steps
On a Windows machine, create and build a flutter project on a different drive than that your Flutter SDK is installed in.
