## What it is
A Flutter package providing a BeforeAfter widget that displays the difference between two images via a draggable slider. It is 100% Dart, supports horizontal/vertical slider directions, and offers extensive customization of the track, thumb, and callbacks.

## Use cases
- show before and after photo comparison in a flutter app
- add an image comparison slider widget to flutter
- compare edited vs original images with a draggable slider
- display image diff with vertical or horizontal swipe
- build a photo retouching before/after preview in dart
- customize slider thumb and track for image comparison

## When to choose
- you are building a Flutter app and need a polished before/after image comparison widget
- you want a pure-Dart solution with customizable slider direction, thumb, and track styling
- you need cross-platform support including mobile, desktop, and web

## When to avoid
- you need image diffing or pixel-level comparison analysis rather than a visual slider
- your project is not Flutter/Dart based
- you need a package under active development with frequent updates
