 This is a convenience wrapper around [`<VirtualizedList>`](virtualizedlist.md), and thus inherits its props (as well as those of [`<ScrollView>`](scrollview.md) that aren't explicitly listed here, along with the following caveats:
 
 - Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
