Steps to reproduce

create a OverlayPortal.targetsRootOverlay widget with a Tooltip inside

Expected results

Tooltip should display on hover

Actual results

No tooltip assertion failed renderer.parent != null

_buildTooltipOverlay fails on
box.localToGlobal because
getTransformTo assetion
assert(renderer.parent != null) fails

Workaround
Add Overlay in the Tooltip hierarchy
Or use OverlayPortal instead of OverlayPortal.targetsRootOverlay

Code sample

       OverlayPortal.targetsRootOverlay(
        controller: OverlayPortalController(),
        overlayChildBuilder: (_) => Tooltip(message: 'Some msg', child: anyChild),
        child: anyChildAgain,
        )
