Yes, yet another React Virtual List... Why?
Just because, all of the other dynamic lists just didn't perform the way I needed, I bit the bullet and wrote a new one that uses a fancy algorithm for dynamic height items that doesn't need to measure intermediate items and provides some handy helper functions and events.
This component:
- Provides dynamic item heights
- Only measures what it draws, estimates the rest and keeps everything smooth by adjusting scroll position when sizes are discovered later
- Does not need to measure intermediate items when large scrolling, massively improving performance
- Does not need an accurate estimated item height
- Allows items to change size at any time
- Allows natural browser layout of the components on screen within their standard container, no individual item positioning
- Works in environments that don't constantly fire scroll events (e.g. iOS)
Example of the dynamic list embedded in a Material UI modal, shown with optional scroll indicating holder component, supplied but not required.
This component uses a O(Ln2) algorithm to work out the position of items and caches all of this for maximum performance even when scrolling huge distances.
Provides events that enable any number of items.
