Flutterflow has some really awesome features.

In the app builder space, it's definitely one of the better tools out there.

You can build web, mobile, and even desktop apps for Windows, iOS and Linux (although those are still being tested).

The interface is complex, but just about as complex as something like Webflow or Bubble. It's a high-functionality, high learning curve tool.

I remember playing with it for a while a few years back, but my main issue with it was their database system. They make you use Firebase, which is more developer friendly than no-coder friendly.

Other no-code tools will use a google sheets style form factor for their backend database. It's easy for even non-tech people to get.

Flutterflow doesn't do that, but that's really my only qualm.

I'll likely stick with Bubble for now, because they recently released a native app builder, and I'm already familiar with their system - but Flutterflow is a real competitor at the top of the line.
