Performance in Flutter and React Native

Hello All, I am working on a freelance project and I want to know which one is good in performance between flutter and react native. Yesterday I search on google and according to this source, The use of JavaScript Bridge to enable communication between native components affects the overall application performance. This is so because we write the code in JS but it is trans-piled to the native code of the mobile platform, which takes time. but not an idea about flutter. Can anyone know about flutter performance? which one is good between them?
