vm-service crashes if path to flutter starts with two slashes (/) #7279
Description
Flutter was working just fine a few weeks ago, however it appears to be broken on my system. I cleaned my existing install and re-cloned and installed flutter, but it seems to fail with the following problem:
Akshays-MacBook-Pro-2:~ akshaydashrath$ flutter doctor
Downloading Dart SDK 1.21.0...

vm-service: Error: Unhandled exception:

I've recently updated MacOS to 10.12.2 apart from that I can't identify any other changes I've made that could affect the system.
