final json = {
  "runtimeType": "Container",

   "runtimeType": "Text",
     "data": "Hello World!"
  }
};

FlutterWidget.json(
 json: json,
);

URL

final url = 'localhost:8080/widget.json';

FlutterWidget.network(
  request: NetworkHttpRequest(url: url),
);

final asset = 'assets/widget.json';

FlutterWidget.asset(
  assetPath: asset,
