KSmoothListView class
A ListView that provides buttery-smooth scrolling on desktop platforms while maintaining native scroll behavior on mobile.
This widget wraps Flutter's standard ListView and adds:
- Continuous frame-by-frame scroll updates (no lag/freeze)
- Platform-tuned momentum physics
- Immediate response to scroll input
On mobile platforms, it behaves exactly like a standard ListView with zero performance overhead.
Example:
SmoothListView.builder(
itemCount: 100,
itemBuilder: (context, index) => ListTile(
title: Text('Item $index'),
),
)
