Answer 1

Your CarouselModel's image variable data type is String. But reading a map can provide null data for unknown keys(the keys arent include on map).

You can provide default value on null case or do a null check then add into list.

Providing default empty string on null case.

=> CarouselModel(item['image']??"")).toList()

If item is nullable do item?['image']??""
