CodePudding user response：

You can pass the course name as an argument while navigating to you next screen.

Navigator.push(
    context,
    PageTransition(
        type: PageTransitionType.rightToLeft,
        child: XDSections(),
    ),
    arguments: {'courseName': "PASS_YOUR_VALUE_HERE"}
);

On your next screen you can get that value by following:

var arguments = ModalRoute.of(context).settings.arguments;

CodePudding user response：

You can use (arguments) parameter in Navigator.push() in order to pass data from one page to another. Example:

              Navigator.push(
                  context,
                  MaterialPageRoute(
                    builder: (context) => XDSections(),
                    settings: RouteSettings(
                      arguments: "Passed Data",
                    ),
                  ),
                );

and for receiving it on XDSections Build Widget:

final args = ModalRoute.of(context)!.settings.arguments as String;
