I believe compositing_test needs to be fixed since it is missing elevation required parameter(marked required in #18933):

      return builder.pushPhysicalShape(path: Path(), color: const Color.fromARGB(0, 0, 0, 0), oldLayer: oldLayer as PhysicalShapeEngineLayer);

https://github.com/flutter/engine/blob/master/lib/ui/compositing.dart#L560

  PhysicalShapeEngineLayer? pushPhysicalShape({
    required Path path,
    required double elevation,
    required Color color,
    Color? shadowColor,
    Clip clipBehavior = Clip.none,
    PhysicalShapeEngineLayer? oldLayer,
  }) {

I imagine some change in rolled dart sdk analyzer implemented this check now, that is why it only got flagged now.

Landing this PR (the bot redness appears to be a flaky test). Dart rolls have been backed up by 2 days and wanted to get it back before the branch cut next week.
