关于我的问题here
我想解析一个JSON数组而不在JSON数组中包含键,并将其放入Model类中。
这是我要解析的JSON数组。
[
{
"pk": 100,
"user": 5,
"name": "Flutter",
"details": "Fluttery",
"images": [
89,
88,
87,
86
],
"priority": 5
},
{
"pk": 99,
"user": 5,
"name": "",
"details": "h",
"images": [],
"priority": 5
},
{
"pk": 98,
"user": 5,
"name": "Flutter",
"details": "Fluttery",
"images": [
85
],
"priority": 5
},
]
我已经成功解析了主数组,但是无法解析包含整数数组的images
键。我想将其放入Model类。请帮忙。
谢谢!

您可以这样操作:
final jsonList = json.decode(response.body) as List;
final userList = jsonList.map((map) => User.fromJson(map)).toList();
用户类别
class User {
final int pk;
final String name;
final List<int> images;
User._({this.pk, this.name, this.images});
factory User.fromJson(Map<String, dynamic> json) {
return new User._(
pk: json['pk'],
name: json['name'],
images: (json['images'] as List).map((map) => int.parse("$map")).toList());
}
}
打印数据
for (var i = 0; i < userList.length; i++) {
print(userList[i].name);
final imageList = userList[i].images;
for (var j = 0 ; j < imageList.length; j++){
print("image: ${imageList[j]}");
}
}

能否请您参考使用dart:convert 部分here手动序列化JSON。如果您仍然遇到问题,请发布错误/困难。
