RelativeScale is a Flutter package that provides a custom sizing system to ensure consistent physical dimensions across devices. By scaling widget sizes relative to screen density and size, it helps maintain visual consistency regardless of device type or resolution. Designed for responsive UI development, it simplifies creating layouts that appear uniform on Android, iOS, Web, macOS, Windows, and Linux. The package uses a base scale factor derived from the device's screen characteristics, enabling developers to define sizes in a way that translates to real-world measurements. It’s ideal for apps where precise visual alignment and proportional design are critical.
