嗨，我想知道如何在创建列表的其他类上访问列表的项目。尤其是我想在Restaurant Screen类上访问restaurantList的项目。
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:projectfooddelivery/Src/models/restaurant.dart';
List<Restaurant> restaurantList=[
Restaurant(image:"kfcloja.jpg",distance: "2 miles away",location:"Shoprite do magoanine",restaurantName: "KFC"),
Restaurant(image:"dominos.jpg",distance: "0.9 miles away",location:"Downtown",restaurantName: "Dominos"),
Restaurant(image:"kfclogo.png",distance: "2 miles away",location:"Shoprite do magoanine",restaurantName: "KFC"),
];//I would like to access the items on the list
class RestaurantWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Container(
height: 350,
child: ListView.builder(
scrollDirection: Axis.vertical,
itemCount: restaurantList.length,
itemBuilder: (_, index) {
return Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
decoration: BoxDecoration(
border: Border.all(
width: 1.0,
color: Colors.grey[100]
),
borderRadius: BorderRadius.circular(20)
),
child: Row(
children: <Widget>[
Container(
width: 150,
child: ClipRRect(
borderRadius: BorderRadius.circular(20),
child: Image.asset("images/${restaurantList[index].image}",fit:BoxFit.cover ,)
)
),
Padding(
padding: const EdgeInsets.all(3.0),
child: Container(
padding: EdgeInsets.all(2),
height: 70,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text("${restaurantList[index].restaurantName}",style: TextStyle(fontWeight: FontWeight.bold),),
Row(
children: <Widget>[
Icon(Icons.star,size: 15,color:Colors.yellowAccent,),
Icon(Icons.star,size: 15,color:Colors.yellowAccent),
Icon(Icons.star,size: 15,color:Colors.yellowAccent),
Icon(Icons.star,size: 15,color:Colors.yellowAccent),
Icon(Icons.star_half,size: 15,color:Colors.yellowAccent),
],
),
Text("${restaurantList[index].location}"),
Text("${restaurantList[index].distance}"),
],
),
),
),
],
),
),
);
},
),
);
}
}
