Data Type of Color.?? to create a model class in Flutter

Question

Hi I've a question to create a json response to model class in flutter.

My response from API is like this :

{

    "status": 200,
    "message": "data fetch successfull",
    "data": [{
            "view_type": 1,
            "heading_title": "Trending Now",
            "trend_list": [{
                "title": "",
                "subtitle": "",
                "price": 1500,
                "display_image": "",
                "size": [6, 7, 8, 9, 10],
                "rating": 4,
                "isFavourite": false,
                "container_color": ["0xFF559BE2", "0xFF2F53CB"],
                "image_shoe": [{
                    "shoe_image": "",
                    "color": "0xFF559BE2",
                    "container_color": ["0xFF559BE2", "0xFF559BE2"]
                }, {
                    "shoe_image": "",
                    "color": "0xFF559BE2",
                    "container_color": ["0xFF559BE2", "0xFF559BE2"]
                }, {
                    "shoe_image": "",
                    "color": "0xFF559BE2",
                    "container_color": ["0xFF559BE2", "0xFF559BE2"]
                }, {
                    "shoe_image": "",
                    "color": "0xFF559BE2",
                    "container_color": ["0xFF559BE2", "0xFF559BE2"]
                }, {
                    "shoe_image": "",
                    "color": "0xFF559BE2",
                    "container_color": ["0xFF559BE2", "0xFF559BE2"]
                }]
            }]
        }
    ]
}

So My Problem is in Container Box Decoration gradient Color accept Color not in String.

So what will be Data type should I add in Model class.?
