I love Flutter. It made all this so much easier.
Right off the bat, I notice stuttering animations everywhere: Scrolling, swiping back, etc... This is on an iPhone 13.
In one section, the keyboard opened on top of a text-field so I couldn't see what I was typing.
The components are _just_ different enough that I feel something is wrong, but for the most part, I can't tell what it is.
Then there's a bunch of minor stuff. Switches become slightly larger when they change. You cant swipe down modals. You can't drag & release over options in the sheet. I feel like I'm missing buttons more often.
Overall, I get a vague cheap feel. Not so bad that I would outright dismiss the app as a customer, but I would definitely look for alternatives.
This isn't a critique of the app. I think all of these issues are flutter-related.
Regardless I'm sure what you have is a great app here so hope you don't feel like I'm targeting you or your app directly here, and at the end of the day if flutter allows you to make your customers happy more power to you and hope it works out the best for you.
