A question popped into my mind recently: how deep does the view hierarchy of Composables have to be to notice any performance hit?

Depends entirely on what you're doing in your composables. A tree of depth(1) is a problem if your composable function is calculating a precise value of

pi

inside its self. We've also seen very deep trees that had no problems. So, the answer is, it entirely depends.

Thanks Jim, that's very encouraging!

You should always calculate PI on the UI thread 😏
