Layout Inspector: Debug Your UI Hierarchy
Layout Inspector is an X-ray for your app's UI, rendering a live 3D model of your component tree. Use it to debug visual glitches or find performance bottlenecks from deep layouts. The footgun is forgetting it has live updates to catch bugs during animations.
Think of Layout Inspector as an X-ray for your app's UI. It renders a live, interactive 3D model of your view hierarchy, showing exactly how components are nested, sized, and positioned. It's essential for debugging why a view is hidden or misaligned and for diagnosing performance issues from overly complex layouts. A common mistake is only checking the final static layout; its real power is using live updates to see how the UI changes dynamically.
