Can we integrate the exported flutter code into a pre-existing react project? If so, how do we pass data to it (JWT Token etc)?

As the title says, I want to understand if I can implement apps I make in FlutterFlow into one of my React app to implement a feature.

I'm not a developer, but I'd like to understand how would a dev go about doing it as we'd like to experiment on :

1. creating apps made by the product team in flutterflow,
2. having it exported, and
3. implemented in a page in our app etc.

How would we pass data, something like JWT tokens, etc?
