I am on the Flutter dev 1.6.0 version with windows 10 on VSCode Stable branch.

After updating to this version of flutter today, I was finding that the Dart Code extension was lagging and "crashing" after working for about 30-40 minutes worth of time. The extension wasn't crashing the editor but it would basically stop working to a point where I would have to go into my task manager and kill the dart instances. speaking of which, there seemed to be 2-3 open at once at all times while the analyzer was running and often times they would be taking up 100% of my memory (64 gigs on this machine) when these crashes happened. It was really annoying and isn't something that I've ever specifically encountered.

After killing the Dart instances, I would have to restart the analyzer (and sometimes the editor) which would buy me another 30-40 minutes worth of time.

This all happened during one of my live streams though you can't really see whats happening since I kept changing windows when I had to restart the editor. In the entire 2 hour and 30 minute session, I had to restart the editor 3-4 times.

Edit: Running the code in the Emulator and using DevTools didn't seem to change anything or tax the machine anymore then the normal analyzer.
