flutter frontend Draggable Widget

Описание: In Flutter, the Draggable widget allows you to make a child widget draggable within its parent widget. It provides an intuitive way to implement drag-and-drop functionality in your Flutter application's frontend.

Here's an example of how you can use the Draggable widget in your Flutter frontend:
In the example above, we create a Draggable widget with three properties:

child: This is the widget that is draggable. In this case, it's a blue square with the text "Drag me!".
feedback: This is the widget that is displayed as the draggable item is being dragged. It's a semi-transparent blue square with the text "Dragging...".
childWhenDragging: This is the widget that replaces the original child while it's being dragged. It's a slightly transparent blue square.
You can customize the appearance and behavior of the draggable widget according to your requirements by providing different widgets for these properties.

Note that the Draggable widget doesn't handle the dropping behavior. If you want to handle the dropping logic, you would typically use it in combination with a DragTarget widget.

I hope this helps you implement a draggable widget in your Flutter frontend!
