flutter - type 'some model' 不是 type 'same model' 的子类型，但它是
问题描述
当我从服务器获取数据并将其更改为名为 SetupIdeaModel 的模型时，我收到此错误。
type 'SetupIdeaModel' is not a subtype of type 'SetupIdeaModel' where
SetupIdeaModel is from package:onion/models/idea.dart
package:onion/models/Idea.dart:1
SetupIdeaModel is from package:onion/models/Idea.dart
package:onion/models/Idea.dart:1
我说 SetubIdeaModel 不是“SetupIdeaModel”类型的子类型，但它是同一个文件和同一个模型。为什么我会收到此错误。
我用这种方法获取数据。
Future getRequestDetails(String token, String requestId) async {
Response response = await APIRequest().get(
myUrl: "$baseUrl/innovator/idea/request/$requestId",
token: token,
);
try {
List data = [
User().fromMap(response.data['data']['userId']),
SetupIdeaModel().fromJson(response.data['data']['ideaId']),
RequestModel().formJson(response.data['data']),
];
return data;
} catch (e, st) {
print("Error $e");
print("Stacktrace $st");
return "Something went wrong!";
}
}
APIRequest() 是我为请求创建的全局方法。Ans 我也在使用 Dio 包来满足我的要求。
SetupIdeaModel
class SetupIdeaModel {
String id;
String userId;
String typeIdea = "Implemented Idea";
String category; //Or Industry
String experienceYear;
String experienceMonth;
String ideaHeadline;
String ideaText;
Map timeline = {
"timelineType": "date",
"details": null,
};
fromJson(json) {
return SetupIdeaModel(
typeIdea: json['ideaType'],
category: json['industry'],
ideaHeadline: json['headline'],
ideaText: json['idea'],
);
}
SetupIdeaModel({
this.uploadVideo,
this.location,
this.estimatedPeople,
this.whitePaper,
this.id,
this.userId,
this.typeIdea,
this.category,
this.experienceYear,
this.experienceMonth,
this.ideaHeadline,
this.ideaText,
this.timeline,
});
List documents = [];
Map uploadVideo;
String location;
String estimatedPeople;
Map whitePaper;
bool needServiceProvider = false;
bool needInvestor = true;
Map toSendMap() {
return {
"ideaType": typeIdea,
"industry": category,
"industryExperienceInMonth":
"${int.parse(experienceYear) * 12 + int.parse(experienceMonth)}",
"headline": ideaHeadline,
"idea": ideaText,
"timeline": timeline,
"uploadDocuments": documents,
"uploadVideo": uploadVideo,
"targetAudience": "$location",
"uploadPaper": whitePaper,
"estimatedPeople": estimatedPeople,
"needServiceProvider": "$needServiceProvider",
"needInvestor": "$needInvestor",
};
}
}
将模型与 is FutureBuilder 一起使用
FutureBuilder(
future: getData,
builder: (context, snapshot) {
if (snapshot.hasData) {
User _user = snapshot.data[0];
SetupIdeaModel _idea = snapshot.data[1];
RequestModel _request = snapshot.data[2];

解决方案
Flutter 不会将这两条路径识别为相同的，因为它们的大小写不同。修复您的导入，以便它们引用相同的文件。
