Overview
Explo is a developer tool for Flutter that visualizes the widget render tree in 3D using an exploded view. It helps developers understand complex UI hierarchies by displaying widgets in a spatial, interactive layout, making it easier to debug and analyze nested structures. The tool runs within the Flutter app during development and provides a dynamic way to explore how widgets are positioned and related. Ideal for identifying layout issues or understanding large widget trees.
