如何添加可拖动的 "textfield" 以在 flutter 中的图像上添加文本？

Question

我正在用 flutter 创建一个 Meme 生成器应用程序..我只需要知道有没有一种方法可以让用户自己在图像上添加文本并将该文本拖动到图像区域的任何位置...这样图片就会看起来很有趣。我尝试了拖动框小部件，但不知道如何将它用于文本字段。这样我也可以将我的文本移动到图像上的任何位置。I need something like this

    class TextOverImage extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
        Size size = MediaQuery.of(context).size;
        return Scaffold(
        appBar: AppBar(
            centerTitle: true,
            title: Text('Text Over Image Image Example'),
        ),
        body: Center(
            child: Container(
            height: 300,
            width: 300,
            child: Stack(
                children: <Widget>[
                Container(
                    decoration: BoxDecoration(
                        borderRadius: BorderRadius.circular(5),
                        color: Colors.blue,
                        image: DecorationImage(
                            image: new NetworkImage(
                                "https://thumbs.dreamstime.com/b/funny-face-baby-27701492.jpg"),
                            fit: BoxFit.fill)),
                ),
                HomePage()
                ],
            ),
            ),
        ),
        );
    }
    }

    class HomePage extends StatefulWidget {
    @override
    _HomePageState createState() => _HomePageState();
    }

    class _HomePageState extends State<HomePage> {
    Offset offset = Offset.zero;

    @override
    Widget build(BuildContext context) {
        return Container(
        child: Positioned(
            left: offset.dx,
            top: offset.dy,
            child: GestureDetector(
                onPanUpdate: (details) {
                setState(() {
                    offset = Offset(
                        offset.dx + details.delta.dx, offset.dy + details.delta.dy);
                });
                },
                child: SizedBox(
                width: 300,
                height: 300,
                child: Padding(
                    padding: const EdgeInsets.all(8.0),
                    child: Center(
                    child: Text("You Think You Are Funny But You Are Not",
                        textAlign: TextAlign.center,
                        style: TextStyle(
                            fontWeight: FontWeight.bold,
                            fontSize: 28.0,
                            color: Colors.red)),
                    ),
                ),
                )),
        ),
        );
    }
    }
