Overview
Responsive Sizer is a Flutter package that simplifies creating responsive layouts across different screen sizes and orientations. It provides helper widgets and extension methods to easily scale fonts, sizes, and spacing based on the device's screen dimensions. By using logical units like `vs` (vertical size) and `hs` (horizontal size), developers can ensure consistent UI appearance on various devices. The package integrates seamlessly into existing Flutter projects and supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux.
