Summary

On Android, custom-view markers moved by Reanimated disappeared, and then flickered, whenever their zIndex changed their draw order.

Fabric moves a reordered child by removing it from the map view and inserting it again. The removal took the Google marker off the map:

• Disappearing: the insert did nothing. A custom-view marker is only added after its first layout, and an already laid-out view gets no new layout. So the marker never came back.
• Flicker: after re-adding it, every reorder still deleted the Google marker and created a new one with a new icon bitmap.

The example's Reanimated fleet shows both, because each truck's zIndex follows its latitude. Path motion doesn't change zIndex, so it was not affected.

Fixes:

• LuggMapView waits one loop before it removes a child's map object. If Fabric inserts the same view again first, the removal is cancelled, and the marker, its icon and its position are not touched. This also covers polylines, polygons, circles and the other overlays. Children that are really removed are still removed on the next loop.
• syncMarkerView adds a marker back when a custom view that has already been laid out is inserted again in a later batch. Custom views still wait for their first layout.

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Test Plan

Android emulator (Pixel 10 Pro XL), Release build of the bare example: Motion: Reanimated, Fleet (10) and Fleet (50).

• Before: within about 10 s, every fleet truck disappears. Logging showed removeMarkerView calls for markers that were still mounted, with no add after them.
• With the first fix: the trucks stay, but they flicker on every reorder.
• With both fixes: all trucks stay and don't flicker. Logging showed that each Google marker was created once at startup and never again during 40 s of motion with 50 trucks.
