I think the biggest benefit of Flutter, speaking as a developer, is that the design choices have been abstracted away. It feels like SquareSpace or Lego for mobile app design. I compose the component hierarchy and then the app looks, for the most part, like I want it. In contrast to React Native, where there are a lot more fiddly bits and CSS that I'm not interested in. On the other hand, stepping outside the bounds of the framework becomes much more difficult, so it's a double edged sword. But I'm a simple type, I like Bootstrap just fine - Flutter does things well enough for the most part.
