README

Excerpt

Tracing Recompositions at Runtime — `@TraceRecomposition`, logcat, and the live heatmap

Layout Inspector counts recompositions and surfaces Argument Change Reasons, but it works only in debug, where Live Literals and the interpreted Compose runtime inflate counts. @TraceRecomposition from skydoves/compose-stability-analyzer instruments a composable at compile time and emits per-recomposition diffs (which state changed, what value transition) to logcat under the Recomposition tag. The instrumentation works in any build the developer enables it for — including release-with-debug-symbols — and feeds the IntelliJ / Android Studio plugin's live recomposition heatmap.
