SAP Marketing Cloud dynamic customer profile的作用（sap consumer industry cloud）

The marketing expert plans an email campaign to launch a new product. An account executive calls the marketing expert and asks to include a specific customer in the campaign. The marketing expert is interested in a 360° view of this customer, and looks for a contact person.

By accessing the corporate account details, the marketing expert can analyze the company of the customer. The contact profile allows the marketing expert to analyze the interest of a single person, and to find the right contact person.

Using the Profile Dashboard, the marketing expert can analyze interest and trends of all contacts.

In Sentiment Engagement, the marketing expert can analyze and process data that has been harvested from internal or external channels.

With Customer Journey Insight, marketing experts can explore the sequence of interactions performed by customers over time, using various channels, such as social media and phone. Interactions such as clicked ads and opened emails can be analyzed.

Using the Analytics and Reports Gallery, marketing experts can run analytics stories, and reports based on predefined CDS views. For more information, see section Analytics.

'WhereIterable>' 不是类型 'List>' 的子类型

如何解决''WhereIterable<Map<dynamic, dynamic>>'' 不是类型 ''List<Map<dynamic, dynamic>>'' 的子类型

有人请帮忙...我快被这个气疯了！

如果我有：

void main() {
  List<Map> people = [];
  people.add({''name'': ''Patrick'',''age'': 56});
  people.add({''name'': ''Jeannette'',''age'': 55});
  print(people.where((person) => person[''name''] == ''Patrick''));
}

正如预期的那样，输出是： （{姓名：帕特里克，年龄：56}）

但是如果我把 where 放在一个类中，就像这样：

class People {
  List<Map> people = [];
  void add(Map data) {
    people.add(data);
  }
  List<Map> get filtered {
    return people.where((m) => m[''name''] == ''Patrick'');
  }
}
void main() {
  People people = People();
  people.add({''name'': ''Patrick'',''age'': 55});
  print(people.filtered);
}

我得到： 未处理的异常： 类型 ''WhereIterable

Firebase/Flutter：编译器读取 map 作为 map 无法解决：/

如何解决Firebase/Flutter：编译器读取 map<String, dynamic> 作为 map<dynamic, dynamic> 无法解决：/

我正在使用 Firebase 创建身份验证服务，并且我有 usermodel 来处理用户数据，我有一个带有函数的类：

class usermodel extends ChangeNotifier {
  late String uid;
  late String username;
  late String email;
  late String password;
  late String type;
  usermodel.empty();
  usermodel(
      String uid,String username,String email,String password,String type) {
    this.uid = uid;
    this.username = username;
    this.email = email;
    this.password = password;
    this.type = type;
     }
  Map<String,dynamic> toMap(usermodel user) {
    var data = Map<String,dynamic>();
    data["uid"] = user.uid;
    data["nickname"] = user.username;
    data["email"] = user.email;
    data["password"] = user.password;
    data["type"] = user.type;
    return data;
  }
}

还有一个我有验证功能的类：

class AuthenticationService {
  final FirebaseAuth _firebaseAuth;
  usermodel usermodel = usermodel.empty();
  final userRef = FirebaseFirestore.instance.collection(''users'');
  AuthenticationService(this._firebaseAuth);
  Stream<User?> get authStateChanges => _firebaseAuth.authStateChanges();
  Future<void> addUserToDB(
      {required String uid,required String username,required String email,required String password,required String type}) async {
    usermodel = usermodel(uid,username,email,password,type);
    var firebaseUser = FirebaseAuth.instance.currentUser;
    await userRef.doc(uid).set(usermodel.toMap(usermodel));
  }
}

我有一个错误：

无法将参数类型“Map”分配给参数类型“Map”。

任何想法如何解决它？

我暂时没有使用 usermodel，但我真的很想修复它。

解决方法

Flutter FCM CastMap

如何解决Flutter FCM CastMap<dynamic, dynamic, String, dynamic>

发送通知时，我有如下嵌套数据：

    message = {
                "notification": {
                    "title": "app notification","body": "new message!"
                },"data": {
                    "info":{
                        "id": message_id,"message": message,"img": img
                }
               }
              }

我这样做的原因是有时 img 为空，我也想发送该信息。如果我将它放在 info 之外，null 值会被丢弃。

当我检查通知数据的 runtimeType 时，我得到 CastMap<dynamic,dynamic,String,dynamic>，我什至不知道那是什么类型的数据。我正在尝试通过执行 Map<String,dynamic> 将其转换为 Map<String,dynamic>.from(event)，但它一直告诉我

Unhandled Exception: type ''String'' is not a subtype of type ''Map<dynamic,dynamic>

CastMap<dynamic,dynamic> 究竟是什么，我如何从中提取 event[''data''][''info'']？

解决方法

json.decode(event[''data''][''info''])

Flutter Unhandled Exception: type '(dynamic) => dynamic' 不是类型 '(dynamic) => bool' of 'test' 的子类型

如何解决Flutter Unhandled Exception: type ''(dynamic) => dynamic'' 不是类型 ''(dynamic) => bool'' of ''test'' 的子类型

我正在从类似这样的 api 获取数据

control + c

我需要做的是在同样有效的数组中添加项目。但我需要做的是我需要添加那些具有 { "Categories": [{ "ID": 1064,"Name": "Pizza","Subcategories": [{ "ID": 87,"CategoryID": 1064,"CategoryName": "Pizza","Items": [{ "ID": 1195,"Name": "Fajita Pizza (S)" "IsFeatured": true },{ "ID": 1196,"Name": "Fajita Pizza (M)" "IsFeatured": true },{ "ID": 1197,"Name": "Fajita Pizza (L)","IsFeatured": false,} ] },{ "ID": 87,"Name": "Fajita Pizza (S)" },"Name": "Fajita Pizza (M)" },"Name": "Fajita Pizza (L)" } ] } ] },{ "ID": 1064,"Subcategories": [{ "ID": 87,"Items": [{ "ID": 1195,"Name": "Fajita Pizza (S)" "IsFeatured": true,},{ "ID": 1196,"Name": "Fajita Pizza (M)" },{ "ID": 1197,"Name": "Fajita Pizza (L)" } ] }] },{ "ID": 1084,"Name": "beverages","Description": null,"Image": null,"StatusID": 1,"LocationID": 2112,"Subcategories": [] } ],"description": "Success","status": 1 }

我在我的另一篇文章中得到了答案

"IsFeatured": true

它在这个答案中显示了这个错误

  data.forEach((category) {
    if (category[''Subcategories''] != null) {
      category[''Subcategories'']
          .where((subcategory) => subcategory.isFeatured)
          .forEach((subcategory) {
        featured[''Featured''].addAll(subcategory[''Items'']);
      });
    }
  });
  print(featured);

添加我的整个函数代码

 Unhandled Exception: type ''(dynamic) => dynamic'' is not a subtype of type ''(dynamic) => bool'' of ''test''

解决方法

main(List<String> args) {
  List data = api[''Categories''];
  var featured = [];

  data.forEach((category) {
    if (category[''Subcategories''] != null) {
      category[''Subcategories''].forEach((subcategory) {
        subcategory[''Items''].forEach((item) {
          if (item[''IsFeatured''] ?? false) {
            featured.add(item);
          }
        });
      });
    }
  });

  print(featured);
}

const api = {
    "Categories": [{
            "ID": 1064,"Name": "Pizza","Subcategories": [{
                    "ID": 87,"CategoryID": 1064,"CategoryName": "Pizza","Items": [{

                            "ID": 1197,"Name": "Fajita Pizza (L)","IsFeatured": false,}
                    ]
                },{
                    "ID": 87,"Name": "Fajita Pizza (S)"
                        },"Name": "Fajita Pizza (M)"

                        }
                    ]
                }
            ]
        },{

                        "ID": 1196,"Name": "Fajita Pizza (M)"
                    },{
                        "ID": 1197,"Name": "Fajita Pizza (L)"
                    }
                ]
            }]
        },{

        }
    ],"description": "Success","status": 1
};

[{ID: 1195,Name: Fajita Pizza (S),IsFeatured: true},{ID: 1196,Name: Fajita Pizza (M),{ID: 1195,IsFeatured: true}]
