从字符串到对象列表的颤振Http响应体

Question

嗨，我目前正在尝试从API中获取一些数据，以便稍后将其转换为对象类。

我收到的json回答不是一个列表，直接是一个字符串。

}

我想把这个结果转换成一个LightHours，在这里每个人都是一个课小时。

我的主要想法是得到一个List<LightHours> = {Hours,...}

此外，我还尝试执行以下操作：LightPrice lightPrice = LightPrice.fromJson(jsonDecode(response.body));，但它只将每个字段作为null。

但是使用json到Dart转换器，它不允许我。

如何将该响应转换为两个对象类？

Answer 1

//your json string
String jsonString = json.encode(data);

//convert json string to list
List<String> newData = List<String>.from(json.decode(jsonString));

这将有助于转换

Answer 2

像这样的事情也许会奏效：

List<LightPrice> list = (jsonDecode(response.body) as Map<String,
    Map<String, dynamic>>).values.map<LightPrice>((value) =>
    LightPrice.fromJson(value)).toList();
