Processing Large Files – Java, Go and 'Hitting the Wall'
For flutter it might be different if Android gets expanded with flutter.
I used GWT a few years ago and still have a GWT app in production (which I hope never has to change until decommission).
Its not a coincidence that the mentioned GWT app should get replaced with a complete rewrite and we are at the point where we lay out the options to do that. GWT is marked clearly as "dead" for new developments within the clients infrastructure. Angular an reactjs are the recommended frameworks, even node.js and plain JS is a "allowed" option.
I do not have preferences for any plain JS or not typesafe languages personaly; but with the history of GWT, Dart or Angular.dart is a hard sell in this situation. Taking the Dart way is similar as we took GWT a few years ago, but even more a lockin into something the rest of us isn't doing (that does not mean the best is what others do, but you know what I mean eh?) because Dart is a new language and framework, from where one couldn't get away easy. The same applies to GWT; that code gets not compiled without gwt tools after you opted into GWT.
I hope Dart is making its way to (perhaps) replace Java in Android or make it into an alternative to the default.
For Dart as a Language for the web I don't know yet what happens(who knows). 2x productivity improvements for an App as mentioned in the summit talks is really great, and I think google doesn't advertise that if not true. Even more impressive is, that google choosed Dart to rebuild one of the most business critical WebApps; a thing you won't do if the technology is not rock solid.
So next for us is to recommend and prove whats the way to go for this old GWT app (that runs every day flawlessly) but is a hurt to maintain...
