CodePudding user response：

Colors.white is a type of MaterialColor not Color.

Change your variable declaration to MaterialColor backColor = Colors.white, or even better, just write final backColor = Colors.white.

There's a key difference between a materialColor and Color..

change your variable to: Color backColor = const Color(0xFFFFFFFF);
