ImagePainter.network("https://sample_image.png",
                  key: _imageKey, controller: imageController, scalable: true),
///To change color, strokewidth or paint mode: 
setState((){
    imageController.color = Colors.red;
    imageController.mode = PaintMode.Arrow;
    imageController.strokeWidth = 10.0;
})
///Export the image:
Uint8List image = await _imageKey.currentState.exportImage();
///Now you use [Uint8List] image to convert it to file.
File imgFile = new File('myFilePath/sample.png');
    imgFile.writeAsBytesSync(image);
