You can experiment with different UX approaches much easier.
I am playing with different ways to define a tag for a DONE in Masters of done for some days. And it’s get better (mini steps). Doing this in code would be more frustrating, doing this in Invision would not feel naturally.
And… I got the gradient buttons working and I also got the slight shadow below the input fields working. Google helps. But FlutterFlow can really improve their docs (I know, this takes time).
