Move Launcher to Flutter? #214
Description
The current launcher compilation process is pppaaaaainful. It involves a bunch of extra libraries on top of Go, and it's not pleasant.
We have a Google tool for desktop applications: https://flutter.dev/multi-platform/desktop - so this seems like a good fit.
That being said, it does seem like you need a Windows machine for a windows build, a Linux machine for a Linux build, etc which may be a complicating factor given our reliance on Cloud Build.
Assuming we can resolve #187 - that could resolve this issue.
