The original creator of Flutter actually left Google rather recently and is in the process of building a Dart server project as his next thing. It’s not even at alpha stage yet however it’s VERY new https://github.com/shorebirdtech
I noticed you worked on Flutter at Google for roughly 1 year and then left. What was your motivation? Was there a problem in the Flutter organisation?
For me personally, working at Google wasn't my first choice as I ended up there when the startup I worked at before was acquired. I just felt done with the whole Silicon Valley thing and ended up moving back to Sweden. If I'd pick one big company to work for, it would probably be Google.
