CodePudding user response：
If you are in control of the API I'd highly suggest restructuring the response in such a way that you don't have any dynamic keys. It's much more conventional and also easier to work with. For your example you could change this part
{
"AbuDhabi": [
{
"id": 33,
"value": "Al Ain",
"selected": false
},
{
"id": 34,
"value": "Abu Dhabi",
"selected": false
}
]
}
to
{
"name" : "AbuDhabi",
"cities" : [
{
"id": 33,
"value": "Al Ain",
"selected": false
},
{
"id": 34,
"value": "Abu Dhabi",
"selected": false
}
]
}
And then maybe rename the outer "cities" to "emirates"

Use this JsontoDart to convert json response to Model.
CodePudding user response：
You can use the following website to convert your JSON to POJO class -
https://javiercbk.github.io/json_to_dart/
Your Response class will be like this -
class Response{
String? code;
String? message;
Data? data;
Response({this.code, this.message, this.data});
Response.fromJson(Map<String, dynamic> json) {
code = json['code'];
message = json['message'];
data = json['data'] != null ? new Data.fromJson(json['data']) : null;
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['code'] = this.code;
data['message'] = this.message;
if (this.data != null) {
data['data'] = this.data!.toJson();
}
return data;
}
}

String? mobile2;
