这里有什么问题。我想是因为我将对象存储在列表中,所以我如何解决它的错误是“_InternalLinkedHashMap
class HomeModel
{
bool status;
HomeDataModel data;
HomeModel.fromJson(Map<String, dynamic> json) {
status = json['status'];
data = HomeDataModel.fromJson(json['data']);
}
}
class HomeDataModel
{
List<BanarModel> banners;
HomeDataModel.fromJson(Map<String, dynamic> json) {
json['banners'].forEach((element) {
banners.add(element);
});
}
}
class BanarModel
{
var id;
String token;
String image;
BanarModel.fromJson(Map<String, dynamic> json) {
id = json['id'];
token = json['token'];
image = json['image'];
}
}
HomeModel homeModel;
void getHomeData(){
emit(ShopLoadingHomeDataStat());
DioHelper.getData(url: Home,token:token ,).then((value){
homeModel=HomeModel.fromJson(value.data);
print(homeModel.data.banners[0].image);
emit(ShopSuccessHomeDataStat());
}).catchError((onError){
print(onError.toString());
emit(ShopErorrHomeDataStat(error: onError));
});

我打开应用时直接调用
BlocProvider(create: (Context)=>ShopCubit()..getHomeData())
答案 0 :(得分:1)
像下面这样更新您的 <!DOCTYPE html>
