I mean my opinion is bit harsh don’t it personally, it’s a point of view of productivity wise, flutter can be better performant.
Flutter is a failure, there is no reason to learn it.

It’s literally a matter of community size.
why learn dart if you just use js and react-native… it’s just better maintained.
