我想列出一些不同的烤肉店。我創建了一個包含我需要的所有屬性的串列，但顫動無法識別或顯示屬性“名稱”或 Listview 構建器中的任何其他屬性，并且
我不明白為什么我感謝每一個有用的命令。
錯誤：
沒有為“List Doener”型別定義吸氣劑“影像”。
并且這個 Doenerscrollliste 類位于 body 容器中。
class DoenerScrollListe extends StatefulWidget {
const DoenerScrollListe({Key? key}) : super(key: key);
@override
State<DoenerScrollListe> createState() => _DoenerScrollListeState();
}
class _DoenerScrollListeState extends State<DoenerScrollListe> {
late PageController _pageController;
int initialPage = 1;
@override
void initState() {
super.initState();
_pageController = PageController();
}
@override
void dispose() {
super.dispose();
_pageController.dispose();
}
@override
Widget build(BuildContext context) {
return ListView.builder(
itemCount: Doener_all.length,
scrollDirection: Axis.vertical,
addAutomaticKeepAlives: false,
shrinkWrap: true,
itemBuilder: (context, index) => Container(
height: 120,
width: double.infinity,
margin: const EdgeInsets.all(10),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20),
color: Colors.orange[400],
image: DecorationImage(image: AssetImage(Doener_all.image))),
),
);
}
}
和我的模型檔案
import 'package:flutter/material.dart';
class Doener {
final String name;
final String image;
final String ratingImage;
final String price;
final String describtion;
Doener({
required this.name,
required this.image,
required this.ratingImage,
required this.price,
required this.describtion,
});
}
// ignore: non_constant_identifier_names
List<Doener> Doener_all = [
Doener(
name: "Rüyam",
image: "assets/images/Ryam.jpg",
ratingImage: "dsd",
price: "4,10",
describtion: "Sehr guter D?ner Top Preis Leistung"),
Doener(
name: "Pamfeliya",
image: "assets/images/Pamfilya.jpg",
ratingImage: "asdaa",
price: "4,10",
describtion: "Bestes Fleisch",
),
Doener(
name: "K'Ups",
image: "assets/images/KUps.jpg",
ratingImage: "sdsd",
price: "4,10",
describtion: "Guter D?ner"),
];
uj5u.com熱心網友回復：
在這種情況下，您希望獲取特定影像，請替換
AssetImage(Doener_all.image)
和
AssetImage(Doener_all[index].image))
更多關于List.
