How can I use widget parameters as variables?-CodePudding

I cant use the parameter variable.

class HomePage extends StatefulWidget {
  const HomePage({
    Key? key,
    required this.userState,
    required this.currentPageForRoute,
  }) : super(key: key);
  final bool userState;
  final int currentPageForRoute;


  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
int currentPage = widget.currentPageForRoute;

//And then, i going to change currentPage often and use it.

}

I want use widget.currentPageForRoute as currentPage variable, but i cant. (If I can use it, I will change it often.) The error massage: Undefined name 'widget'.

CodePudding user response：

You can use initState method or late

late int currentPage = widget.currentPageForRoute;
