  decoration: BoxDecoration(
          image: DecorationImage(
            image: AssetImage(card._imgPath)
          ),}`

Answer 1

You can solve this issue by changing your code like this

dynamic card = BusinessCard;

to

dynamic card = BusinessCard();

In fact you are trying to get imagePath in BusinessCard which is a type not a value. You need to create an instance of this class before accessing instance variables (by calling default constructor with ExampleClass()or by calling static constructor like ExampleClass.fromTest(test)).

Answer 2

It looks like you didn't give any parameter to your BusinessCard constructor when declaring the variable card. Also you named your getter _imgPath. In Flutter if you put an _ in front of something it means that it is private so you don't have access to it outside from its class.
