Fix: Correct lane assignments when lane count changes dynamically (#1095)
Fixed a critical bug where changing the number of lanes dynamically would cause layout breakage with incorrect lane assignments. When the lane count changed (e.g., from 3 to 2 columns in a responsive masonry layout), some virtual items would retain their old lane numbers, causing out-of-bounds errors and broken layouts.
Root Cause: After clearing measurements cache on lane change, the virtualizer was incorrectly restoring data from
initialMeasurementsCache, which contained stale lane assignments from the previous lane count.Fix: Skip
initialMeasurementsCacherestoration during lane transitions by checking thelanesSettlingflag. This ensures all measurements are recalculated with correct lane assignments for the new lane count.Before:
After:
This fix is essential for responsive masonry layouts where column count changes based on viewport width. No performance impact as it only affects the lane change transition path.
