Flutter：是否可以将鼠标 cursor 更改为“可拖动”小部件的“反馈”小部件？

Question

While dragged widget is dragging I would like to change the cursor to more appropriate SystemMouseCursor.grabbing but unfortunately it is not possible to do this by simple Flutter facilities. Maybe someone already had such experience?

Answer 1

After some brain storming I found the enough simple solution. All what need to be done is wrap the childWhenDragging widget with MouseRegion :

Draggable(
  feedback: <dragging widget>,
  childWhenDragging: Container(
    color: Theme.of(context).colorScheme.secondary.withOpacity(0.1),
    child: MouseRegion(
      cursor: SystemMouseCursors.grabbing,
      child: <draggable child>,
    ), 
  ),
)
