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

class _ShowMeasurementsPageState extends State<ShowMeasurementsPage> {
  final String? name, nohap;
  _ShowMeasurementsPageState({this.name, this.nohap});

can anyone help me?

CodePudding user response：

You'll need to pass the arguments to the StatefulWidget, then you can access them in the build method by using widget.name, or widget.nohap.

For example:

class ShowMeasurementsPage extends StatefulWidget {
  static String tag = 'show-measurements-page';
  final String? name;
  final String? nohap;

  const ShowMeasurementsPage({
    Key? key,
    this.name,
    this.nohap,
  }): super(key: key);

  @override
  State<ShowMeasurementsPage> createState() => 
    _ShowMeasurementsPageState();
}

class _ShowMeasurementsPageState extends State<ShowMeasurementsPage> {
  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        if (widget.name != null)
          Text(widget.name!),
        if (widget.nohap != null)
          Text(widget.nohap!),
      ],
    );
  }
}
