Summary: X-link: react/yoga#1961 Follow-up to D104666335 (Yoga Java→Kotlin migration of `YogaNodeJNIBase`). The original migration kept several `!!` (not-null assertion) operators. Per reviewer feedback, replace them with safer Kotlin idioms: - `addChildAt`: replace the `if (children == null) { children = ArrayList(4) } children!!.add(...)` pattern with a single `val list = children ?: ArrayList<YogaNodeJNIBase>(4).also { children = it }` so the local `val` is statically non-null and lazy-initializes the backing field in one expression. - `swapChildAt`: capture `children` into a local `val` via `checkNotNull(children) { "YogaNode does not have children" }` instead of `children!!.removeAt(...)` / `children!!.add(...)`. Surfaces a clearer `IllegalStateException` instead of a bare `KotlinNullPointerException`. - `cloneWithChildren`: collapse `if (clonedYogaNode.children != null) { clonedYogaNode.children = ArrayList(clonedYogaNode.children!!) }` into `clonedYogaNode.children?.let { clonedYogaNode.children = ArrayList(it) }`. - `measure`: fold the existing `if (!isMeasureDefined) throw RuntimeException(...)` guard into `val mf = checkNotNull(measureFunction) { "Measure function isn't defined!" }`. Same behavior, no double-read of the mutable property. - `baseline`: convert the expression body using `baselineFunction!!.baseline(...)` to a block body that uses `checkNotNull(baselineFunction) { "Baseline function isn't defined!" }`. Yields a clearer error than a bare NPE if `baseline()` is ever invoked when no `YogaBaselineFunction` was set. Both mirrored copies (`xplat/yoga/...` and `xplat/js/react-native-github/...`) are kept in sync. Changelog: [Internal] - Differential Revision: D105300348
