Some values return null when exporting

[Michael Gallego]

Hello, I really like this package and was wondering if I am exporting correctly, because I keep getting null values on some properties. Am I supposed to add a parser before I export or is exporting using DynamicWidgetJsonExportor the best way? And also some properties are not being caught, such as decoration, which I need to provide a background in the container.

Widget:

Container(
                height: 200,
                margin: EdgeInsets.symmetric(horizontal: 15.0),
                decoration: BoxDecoration(
                  borderRadius: BorderRadius.all(Radius.circular(20.0)),
                  image: DecorationImage(
                    image: AssetImage('assets/weather/clear-day/bg.jpg'),
                    colorFilter: ColorFilter.mode(
                        Colors.black.withOpacity(0.75), BlendMode.dstATop),
                    fit: BoxFit.cover,
                  ),
                ),
                child: Stack(
                  children: [
                    Align(
                      alignment: Alignment.topLeft,
                      child: IconButton(
                        onPressed: () => debugPrint('testing'),
                        icon: Icon(Icons.ac_unit),
                      ),
                    ),
                    Align(
                      alignment: Alignment.topRight,
                      child: IconButton(
                        onPressed: () => debugPrint('testing2'),
                        icon: Icon(Icons.access_alarm),
                      ),
                    ),
                  ],
                ),)

exported Json from widget above:

{
    "type": "Container",
    "alignment": null,
    "padding": null,
    "color": null,
    "margin": "15.0,0.0,15.0,0.0",
    "constraints": {
        "minWidth": 0.0,
        "maxWidth": 9999999999.0,
        "minHeight": 200.0,
        "maxHeight": 200.0
    },
    "child": {
        "type": "Stack",
        "alignment": "topStart",
        "textDirection": "ltr",
        "fit": "loose",
        "clipBehavior": "hardEdge",
        "children": [
            {
                "type": "Align",
                "alignment": "topLeft",
                "widthFactor": null,
                "heightFactor": null,
                "child": null
            },
            {
                "type": "Align",
                "alignment": "topRight",
                "widthFactor": null,
                "heightFactor": null,
                "child": null
            }
        ]
    }
}

As you can see, decoration is not being exported, and also my iconbuttons in the stack are all null. Any reason for this?

decoration property is not exported, and "null" is the default value for alignment
