## What it is
A Flutter library for adapting screen and font sizes so UI layouts render reasonably across different device screen sizes. It provides utilities to scale dimensions based on a design draft size and query screen information.

## Use cases
- make my flutter app ui adapt to different screen sizes
- scale fonts and widgets based on design draft size
- responsive layout for phones and tablets in flutter
- convert design mockup dimensions to flutter units
- get screen width height and density in flutter
- support multiple device sizes without layout breaking

## When to choose
- you build Flutter apps that must look consistent across phones, tablets, and different resolutions
- your designs are based on a fixed-size mockup and you want proportional scaling
- you need simple screen information queries alongside size adaptation

## When to avoid
- you use native Android/iOS development rather than Flutter
- you prefer fully responsive constraint-based layouts over proportional scaling
- you need web or desktop-first adaptive layouts with complex breakpoints
