I'm trying to convert a network image into a file and the first part of that is to convert it into a Uint8List. Here is how I'm doing this with 1 of my asset images...

      final ByteData bytes = await rootBundle.load('assests/logo');

      final Uint8List list = bytes.buffer.asUint8List();



      final tempDir = await getTemporaryDirectory();

      final file = await new File('${tempDir.path}/image.jpg').create();

      file.writeAsBytesSync(list);

How can I do this with Image.network(imageUrl.com/image)

  void initState() {

    super.initState();

    var sunImage = new NetworkImage(

        "https://resources.ninghao.org/images/childhood-in-a-picture.jpg");

    sunImage.obtainKey(new ImageConfiguration()).then((val) {

      var load = sunImage.load(val);

      load.addListener((listener, err) async {

        setState(() => image = listener);

      });

    });

  }

Then you can use image.toByteData().buffer.asUInt8List()
