summary
A tiny React Native layout bug actually reveals Yoga’s assumptions: text measured with a full-screen constraint because the icon size hasn’t propagated up the tree, so adding flexShrink default 0 across RN avoids costly remeasures. Debugging uses breakpoints inside Yoga’s C++ calculateLayout and an Expo sample app; native text measurement (UIKit/Android) is the expensive part — text measuring ≈50–60% of Yoga time. Yoga 3.0 and the useWebDefaults flag change defaults toward web behavior; the fix works and explains why flex:1 was needed.
