There’s a weird error saying that The argument type ‘Color?’ can’t be assigned to the parameter type ‘Color’ when I try to assign the color, what is going on here?

    You can use Theme.of(context) to get the color(and other property).

     color: color?? Theme.of(context).scaffoldBackgroundColor.withOpacity(.2)

    And try not to use ! without null check.

    color datatype is Color?
    please change the double datatype to Color?

    final double color; 
to this 
final Color? color;

    you can not assign double value to the color as you have defined color property of double data type.Change the data type of color to the Color like this:

    final Color color;

    if you wan to use hex color code you can do it like this

    Color(0xffb74093)

    in this the b74093 is the hex code of the color.
