Draggable element with tracking x and y position in flutter. To use a Draggable like this,
1. You’ll need to be able to set the element’s position, something like Positioned and its left,top.
2. Then you’ll need to get the ending coordinates of the drag, using dragDetails from onDragEnd: (dragDetails) { }
Here’s a simple sample to start you off:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | Positioned( left: _x, top: _y, child: Draggable( child: FlutterLogo(size: _logoSize), feedback: FlutterLogo(size: _logoSize), childWhenDragging: Container(), onDragEnd: (dragDetails) { setState(() { _x = dragDetails.offset.dx; // if applicable, don't forget offsets like app/status bar _y = dragDetails.offset.dy - appBarHeight - statusBarHeight; }); }, ), ) |
