I was caching a bunch of data in App State to speed up searching and loading in my app — everything was working fine until suddenly, things started acting weird. After some digging and debugging, I finally figured it out:
FlutterFlow App State has a 999 key/value limit.
Yup, turns out if you try to store more than 999 items in App State, things just stop working as expected. I was storing a lot of structured data for quick access, and unknowingly hit that ceiling.
Kind of a strange limitation, but now it makes sense why the app was breaking silently. So if you’re using App State like a mini cache or local store, make sure you’re not crossing that limit — or better yet, consider alternatives like local storage or querying data more efficiently.
Hope this helps someone avoid the same rabbit hole I went down! 😅
