Expose drop offset in DragTarget for onWillAccept #131378
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Use case
User drags a Draggable from one widget to another widget, and needs to know where within the latter widget's DragTarget the drop will occur before deciding if it's going to be accepted or not. The former widget may not still be mounted at this point.
Proposal
As a continuation of #55184, we should also expose drag details for onWillAccept in DragTarget.
