The UIDebugger is a replacement for the Layout inspector. It streams the full hierarchy of the running app to flipper desktop in near real time. We display a 2D visualization with all of your view and component bounds overlayed on top. You can focus on a particular view or component from the context menu. Additionally, you can pause incoming updates to focus on a particular frame.
You can inspect what views the hierarchy is made up of as well as what properties each view has; this is useful when debugging issues with your product.
We currently support Native android and Litho components, it integrates with these frameworks to present components in the hierarchy just as if they were native views, exposing all the layout properties, props, and state of the components.
