🚀 Why Use annotated_slider?

Flutter’s built-in slider is functional, but lacks customization for real-world UX needs like:

✅ Marking meaningful thresholds (e.g., "Low", "Optimal", "High")
✅ Positioning labeled markers on the track
✅ Custom drawing of marker shapes (circles, icons, etc.)
✅ Full control over theme, tick marks, overlay, and more

• 🎨 Full theming support via AnnotatedSliderTheme.
