⚡ PerformanceListView

Stop reinventing the wheel. PerformanceListView is a production-ready, drop-in replacement for Flutter's standard ListView/GridView. It eliminates boilerplate by handling Pagination, Pull-to-Refresh, Error States, and Memory-Optimized Caching right out of the box.

🚀 Why PerformanceListView?

Standard Flutter lists become complex quickly when you add infinite scrolling and remote images. PerformanceListView solves:

• Jank-Free Scrolling: Uses RepaintBoundary to isolate item paints.
• Memory Bloat: PerformanceImage automatically resizes images to their display size in memory.
• Boilerplate: No more manual ScrollController listeners for pagination.
• Robust UX: Built-in "Retry" buttons for errors and "Empty" states for no data.

✨ Key Features

• Auto-Pagination: Simple onEndReached callback.
• Grid Support: Easy switch to PerformanceListView.grid.
• Sliver Ready: Exported as SliverPerformanceListView for complex CustomScrollView layouts.
• Smart Caching: Built-in wrapper for CachedNetworkImage with optimized memory usage.
• Refreshable: Seamless integration with RefreshIndicator.
