How can I view the details of an item in a detailed screen - Flutter

Question

I am new to flutter this error is giving me a serious nightmare. I have a card list of items called Anchors. These items are coming from the shared preference file which belongs

Answer 1

The problem seems to be here

detailsPage(value : anchors[i]['Oid'])

You're passing Oid as parameter that is an Int. But look that the constructor for detailsPage

List value;
detailsPage({Key key, @required this.value}) : super(key: key);

The parameter value is a List. It's hard for me to know what you're trying to do... but you will need to fix this type mismatch.

EDIT

It seems that value parameter should be of type Map

class detailsPage extends StatefulWidget {
    Map value;
    
    detailsPage({Key key, @required this.value}) : super(key: key);

    @override
    _detailsPageState createState() => _detailsPageState(value);
}

class _detailsPageState extends State {
    Map value;
    
    _detailsPageState(this.value);

    @override
    Widget build(BuildContext context) {
        return Scaffold(
            appBar: AppBar(
                title: Text("Anchors Details Page"),
                iconTheme: IconThemeData(color: Colors.white),
                backgroundColor: Colors.green,
            ),            
            body: Container(
                child: ListView(
                children: [
                    Text(value['Name']),
                    Text(value['Oid'].toString()),
                    ListView.builder(
                        shrinkWrap: true,
                        itemCount: value['DistributionCentres'].length,
                        //context:context, //it saying the name parameter context is not defined
                        physics: NeverScrollableScrollPhysics(),
                        itemBuilder: (BuildContext context, int i) {
                        return Text(value['DistributionCentres'][i]['Name']);
                        })
                ],
                ),
            ),
        );
    }
}

And then you should do

detailsPage(value : anchors[i])));
