React for web will still be around, but I agree Flutter is a much better than RN in many ways (too many to list here). RN is quite an abysmal technology but it has two advantages: 1) it’s familiar (all though flutter is easy to pick up) and 2) it doesn’t shove material UI down your throat. Such a shame that Flutter didn’t make a less visually opinionated framework. In the first 5 minutes you’re wondering how to go about having your own look, theme material UI, theme your own stuff at the same time etc it’s much more off putting than starting with a blank slate
