…View (facebook#38475) Summary: Pull Request resolved: facebook#38475 We added `scrollEventThrottle` for android in D35735978, but the experiment was never executed and the flag got removed in D39449184. Since the same feature is on iOS and the implementation here is the same to iOS (https://fburl.com/code/htcuhq4w), it should be safe to support.

Summary: This is specific to the scenario, and device, and time-based sampling as implemented on Android may inherently create stutters because we may not proess events at a consistent cadence (and we may never process the last events). facebook#38475 made this code no longer no-op on Android, which caused scroll regressions documented in facebook#38470 We are already coalescing scroll events on both Android and iOS, which will ensure we are not flooded with events. Though after this change, it is possible some heavy scenarios will see more time dedicated to FlatList work after this.

We are already coalescing scroll events on both Android and iOS, which will ensure we are not flooded with events. VirtualizedList also already inserts an artificial 50ms delay to new renders by default when high priority work is not happening (see `updateCellsBatchingPeriod`). This limits the heavy work done by VirtualizedList (no new renders or expensive math on scroll events), while letting the list still have the most recent events. We can eventually remove this once VirtualizedList is able to use OffScreen universally.
