I had no idea that development on something like Flutter has already been underway.
In a nutshell it's a way for developers to create one app that fits all. Create an iOS app... and it will also work on Android... and also work on Mac OS... and also work on Windows 10... and also work on Linux.
If this isn't a pipe dream but very real and possible... WOW. The way I see it --
The biggest shortcoming of Linux is the lack of apps. This is a silly example but imagine if every iOS and Android weather app also worked in Linux? Spotify or Apple Music or Netflix were all 'native' to Linux? Flutter would (eventually) fix the app gap and suddenly --
-- Windows users will have a choice between a bloated not so secure platform (Windows 10) and a lean much faster OS that is more secure and less spyware-y. But with plenty of apps. Oh, and speaking of that --
-- the entire point of Chrome OS is to offer such a lean Linux like system -- but -- it's at the cost of privacy. Big Broogle. But a Linux OS full of these new apps can simply be installed over a Chrome book and you get your privacy back.
With apps like this a third phone OS may emerge, which is private (like Apple) but priced like Android. So called 'privacy' is one of the last decent reasons to consider iPhone. Flutter would make that sort of irrelevant.
