Example

class ExampleDragTarget extends StatefulWidget {
  const ExampleDragTarget({Key? key}) : super(key: key);

  @override
  _ExampleDragTargetState createState() => _ExampleDragTargetState();
}

class _ExampleDragTargetState extends State<ExampleDragTarget> {
  final List<Uri> _list = [];

  bool _dragging = false;

  @override
  Widget build(BuildContext context) {
    return DropTarget(
      onDragDone: (urls) {
        setState(() {
          for (final uri in urls) {
            debugPrint("uri: ${uri.toFilePath()} "
                "${File(uri.toFilePath()).existsSync()}");
          }
          _list.addAll(urls);
        });
      },
      onDragEntered: () {
        setState(() {
          _dragging = true;
        });
      },
      onDragExited: () {
        setState(() {
          _dragging = false;
        });
      },
      child: Container(
        height: 200,
        width: 200,
        color: _dragging ? Colors.blue.withOpacity(0.4) : Colors.black26,
        child: _list.isEmpty
            ? const Center(child: Text("Drop here"))
            : Text(_list.join("\n")),
