    PanelDragTargetsState.build is calling RenderBox.globalToLocal during its build, which is not legit. The positions of objects haven't been determined yet at the time build is called.

    Okay. The assert should say as much rather than directing me to file an issue.

    ie. "You are attempting to access the size and/or position of a RenderBox during the build phase. You can't do that." full stop

    By it saying it's a bug in the framework it makes me put the onus on you to fix rather than me.
