Overview
The circular package is a Flutter library designed to create and manage circular sliders for intuitive value selection within a defined range. It enables developers to display and pick data in a visually engaging circular format, ideal for settings like volume controls, angle selectors, or percentage inputs. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, ensuring consistent behavior across devices. With customizable appearance and smooth interactions, it simplifies the integration of circular input mechanisms into Flutter applications.
