Debugging Common Issues with Virtualized Lists

// Ensure list is re-rendered correctly on window resize
window.addEventListener('resize', () => listRef.current.recomputeRowHeights());

This code snippet adds an event listener for window resize events. When the window is resized, it triggers a recomputation of row heights in the virtualized list. This is useful to prevent incorrect item positioning due to changes in the viewport size.

listRef.current.scrollToItem(index, 'start');

This line demonstrates how to scroll to a specific item in the list. It can be used as a debugging tool to ensure that items are correctly positioned within the list without flickering or incorrect offsets.
