The Windows Dart Editor uses "" characters to describe paths, whereas the Mac Editor uses unix-style "/" separators.

This creates useless noise in source control on teams that use both Windows AND Mac.

It would be awesome if you guys could make it so that the paths in pubspec.lock were NOT platform-dependent.

Are you using path dependencies? That this might be a duplicate of issue #950 which was marked as won't fix.
