RectGetter is a Flutter package that simplifies the process of obtaining a child widget's rectangle dimensions and position after rendering. It provides a convenient way to access precise layout information such as offset, size, and bounds within a widget tree. Ideal for gesture detection, animations, or UI alignment tasks requiring accurate spatial data. The package works across all major platforms including Android, iOS, Web, macOS, Windows, and Linux, ensuring consistent behavior regardless of target environment.
