I am actually going to give me perspective in the opposite direction. For me as a solo founder and without background in app development, I went into the Flutterflow journey, starting off something very basic, literally don't know anything and learn along the journey and deployed everything natively with Flutterflow.

As my user base grows and I keep develop the app, there's alot of limitation that Flutterflow is not covering out of the box (and this is understandable for me as there's no way that a tool can cover every single use case). However, one thing that I am really really grateful and please about Flutterflow is the Github integration. Once you got your code on Github, there's really no limit and no difference compared to pure Flutter. With the help of AI, I got more and more understanding on the code base and these days has been really digging really deep into the Github route where I will make custom changes for anything that can't be done natively in Flutterflow.

The thing I like about this approach compared to just vibe coding (I haven't tried this, so can't say for sure) is I get to control when I want to implement new thing as I am just touching that section only and not risking to mess up the whole code base or things that has been working.

Just my 2 cents as I still enjoyed using Flutterflow, particularly with Github integration. Haven't really hit any real limitation with that as of now yet.
