I get stack overflow error in my flutter application

  1. I tried to pass data by using provider between different widget but I got error stack over flow and the code seems nice?.

     '''

 Expanded(
             child: ListView.builder(
               itemCount: items.itemsProvide.length,
               itemBuilder: (ctx, i) => CartItemsDw(
                   items.itemsProvide.values.toList()[i].id,
                   items.itemsProvide.values.toList()[i].title,
                   items.itemsProvide.values.toList()[i].price,
                   items.itemsProvide.values.toList()[i].quatity),
             ),
           )

'''

  2. I try to pass my data to another widget which are below there and when try to access the data for this widget the error appear

    '''

     import 'package:flutter/material.dart';
 class CartItemsDw extends StatelessWidget {
   final String id;
   final String title;
   final double price;
   final int quantity;
   CartItemsDw( this.id,this.title,this.price, this.quantity);
   Widget build(BuildContext context) {
     return Card(
       margin: EdgeInsets.symmetric(horizontal: 10,vertical: 4),
       child: Padding(padding: EdgeInsets.all(8),
       child: ListTile(leading: CircleAvatar(child: Text('\$$price'),),
       title: Text(title),
       subtitle: Text('total \$${(price*quantity)}'),
       trailing: Text('\$$quantity x'),
       ),  
      ),
     );
   }
 }

Keep in mind, Listview.builder is auto expandable and scrollable. Just remove Expanded wrapping from outside the list.

 ListView.builder(
               itemCount: items.itemsProvide.length,
               itemBuilder: (ctx, i) => CartItemsDw(
                   items.itemsProvide.values.toList()[i].id,
                   items.itemsProvide.values.toList()[i].title,
                   items.itemsProvide.values.toList()[i].price,
                   items.itemsProvide.values.toList()[i].quatity),
             );
