It really works wonderful on Flutter Android, however the enter is stuttering or sluggish on iOS

I’m a Korean who’s making an app utilizing Flutter. This app is in Korean, and I wrote the code to mechanically replicate the search outcomes on to Listview.builder in line with the real-time API enter values when looking out (principally in Korean) throughout app improvement.
I checked with debugging mode to see if it labored effectively on the precise system, it labored very effectively on Android as I wished, however on iOS, I had an issue the place the worth did not seem within the checklist view despite the fact that I had enter.
Is that this an issue brought on by the totally different iOS processing strategies of Korean Alphabet? Additionally, while you take a real-time search phrase with Question, Hangeul seems effectively.
