Summary
- Provides a decision tree to diagnose jank on UI thread, Raster (GPU) thread, or both, with specific fixes for each
- Includes integration test templates using traceAction and TimelineSummary to establish performance baselines and measure frame budgets
- Covers UI optimization (localizing state, const constructors, StringBuffer usage) and Raster optimization (replacing Opacity widgets, avoiding expensive clipping)
- Addresses layout inefficiencies, framework breaking changes with LayoutBuilder/OverlayEntry, and web-specific profiling via Chrome DevTools
- Enforces constraints: profile in --profile mode only, avoid operator overrides on Widgets, and use lazy builders for long lists
