i'm seeing a lot of complaints on iOS flutter apps of how the UI looks(microstutters/not frame perfect). it's only the usual small vocal minority but boy do they kill your app's reception on the programmer heavy social media
Can you link a specific issue that wasn't immediately a result of a problem with the user code, perhaps too much work on the main thread?
I have found the perf to be just fantastic on android. Especially compared to react native, which is a native offering.
I think Flutter means native in the sense that it runs at native speed, perhaps even faster in some carefully selected apps
As for a look and feel thing, Flutter widgets feel alright to me..
