I cannot figure it out why it is not working? When i used this in another list it works but this time does not.
Future<UserResponse> login() async {
Map<String, String> headers = {};
headers["Content-Type"] =
"application/json; charset=UTF-8";
final response = await http.get(Uri.parse('http://myserverip/api/Most/Login?username=demo&pass=123456'),
headers: headers);
debugPrint('response\n'+response.body.toString());
final jsonItems = json.decode(response.body).cast<Map<String,dynamic>>();
debugPrint('json\n'+jsonItems.toString());
UserResponse resp = jsonItems.object<UserResponse>((json){
debugPrint('asdasd\n'+UserResponse.fromJson(json).toString());
return UserResponse.fromJson(json);
});
debugPrint('aftercast\n'+resp.locationName.toString());
return resp;
}
This is my output which is json but i cannot match it with my class:
[
{
"id": 1,
"userName": "demo",
"userPassword": "123456",
"isOnline": false,
"isActive": true,
"superVisor": false,
"createdDate": "2022-01-28T16:23:40.07",
"updatedDate": "2022-01-28T16:23:40.07",
"locationName": "Doğanlar",
"address": "Izmir",
"dbhostName": "myserverip",
"dbcatalogName": "Place1",
"dbuserId": "sa",
"dbpassword": "Most123456",
"locationCreateDate": "2022-01-28T15:54:53.887",
"companyName": "Company1",
"authName": "FullAccess",
"unitName": "Production",
"screenName": "Production",
"unitId": 1,
"screenId": 1,
"locationId": 1,
"companyId": 1,
"authId": 5
}
]
This is my UserResponse Class. I think there is no problem from here.
class UserResponse {
int? id;
String? userName;
String? userPassword;
bool? isOnline;
bool? isActive;
bool? superVisor;
String? createdDate;
String? updatedDate;
String? locationName;
String? address;
String? dbhostName;
String? dbcatalogName;
String? dbuserId;
String? dbpassword;
String? locationCreateDate;
String? companyName;
String? authName;
String? unitName;
String? screenName;
int? unitId;
int? screenId;
int? locationId;
int? companyId;
int? authId;
UserResponse({this.id,
this.userName,
this.userPassword,
this.isOnline,
this.isActive,
this.superVisor,
this.createdDate,
this.updatedDate,
this.locationName,
this.address,
this.dbhostName,
this.dbcatalogName,
this.dbuserId,
this.dbpassword,
this.locationCreateDate,
this.companyName,
this.authName,
this.unitName,
this.screenName,
this.unitId,
this.screenId,
this.locationId,
this.companyId,
this.authId});
factory UserResponse.fromJson(Map<String, dynamic> json) {
return UserResponse(
id : json['id'],
userName : json['userName'],
userPassword : json['userPassword'],
isOnline : json['isOnline'],
isActive : json['isActive'],
superVisor : json['superVisor'],
createdDate : json['createdDate'],
updatedDate : json['updatedDate'],
locationName : json['locationName'],
address : json['address'],
dbhostName : json['dbhostName'],
dbcatalogName : json['dbcatalogName'],
dbuserId : json['dbuserId'],
dbpassword : json['dbpassword'],
locationCreateDate : json['locationCreateDate'],
companyName : json['companyName'],
authName : json['authName'],
unitName : json['unitName'],
screenName : json['screenName'],
unitId : json['unitId'],
screenId : json['screenId'],
locationId : json['locationId'],
companyId : json['companyId'],
authId : json['authId'],
);
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['id'] = this.id;
data['userName'] = this.userName;
data['userPassword'] = this.userPassword;
data['isOnline'] = this.isOnline;
data['isActive'] = this.isActive;
data['superVisor'] = this.superVisor;

data['address'] = this.address;
data['dbhostName'] = this.dbhostName;
data['dbcatalogName'] = this.dbcatalogName;
data['dbuserId'] = this.dbuserId;
data['dbpassword'] = this.dbpassword;
data['locationCreateDate'] = this.locationCreateDate;
data['companyName'] = this.companyName;
data['authName'] = this.authName;
data['unitName'] = this.unitName;
data['screenName'] = this.screenName;
data['unitId'] = this.unitId;
data['screenId'] = this.screenId;
data['locationId'] = this.locationId;
data['companyId'] = this.companyId;
data['authId'] = this.authId;
return data;
}
}
Where is the problem of the future? I guess there is an implementation problem for example in casting. Could you help me?
Change your Future method to this.
Future<List<UserResponse>> login() async {
Map<String, String> headers = {};
headers["Content-Type"] = "application/json; charset=UTF-8";
final response = await http.get(
Uri.parse('http://myserverip/api/Most/Login?username=demo&pass=123456'),
headers: headers);
debugPrint('response\n' + response.body.toString());
var jsonItems = json.decode(response.body);
debugPrint('json\n' + jsonItems.toString());
List<UserResponse> resp =
(jsonItems as List).map((e) => UserResponse.fromJson(e)).toList();
// debugPrint('aftercast\n' + resp[0]!.locationName!.toString());
return resp;
}
you can access the response like this.
@override
Widget build(BuildContext context) {
return FutureBuilder(
future: login(),
builder: (context, AsyncSnapshot<List<UserResponse>> snapshot) {
if (snapshot.hasError) {
return const Center(
child: Text('Error'),
);
} else if (snapshot.hasData) {
debugPrint(snapshot.data.toString());
return Center(
child: Text(snapshot.data![0].locationName!),
);
} else {
return const CircularProgressIndicator();
}
},
);
}
